There is no single underground Berlin to buy a ticket for. There are wartime air-raid shelters built into U-Bahn stations, a Cold War nuclear shelter under a working platform, the only original Berlin Wall escape tunnel you can still look into, three floors of a bombed flak tower, the cellars of Tempelhof airport and a Prussian fortress in the far west of the city. Almost all of it is guided-tour-only and booked in advance; the one big exception is the Berlin Story Bunker at Anhalter Bahnhof, which you walk into any day of the year without an appointment. This page sorts them by what English-speaking visitors actually get in, with checked 2026 prices in euros and US dollars – and with the one honest answer to the most-searched question of all: you cannot go inside Hitler's bunker, because it is not there any more.

Seventeen places under Berlin, compared
Berliner Unterwelten: Dark Worlds (formerly Tour 1)
The classic and the right first visit: genuine air-raid shelter rooms on several levels inside Gesundbrunnen U-Bahn station, behind an unremarkable green door. The subject is the bombing of Berlin and civilian air-raid protection, told through finds dug out of government-quarter bunkers, pneumatic post tubes, brewery cellars, sewers and the building of the U8.
For first-timers, history readers and teenagers of about 14 and up. The most frequent tour in the programme and the best served in English – 89 English departures across 26 days in the 30-day booking window checked on 20 September 2026, roughly two thirds as many as the German version. The shelter survived 1945 because blowing it up would have wrecked the U-Bahn tunnel above it; the association rediscovered it in 1998.
€18 (about $20.63), reduced €13, about 90 minutes, online only
Berliner Unterwelten: From Flak Towers to Mountains of Debris (the Humboldthain flak tower)
A walk through the inside of the flak tower ruin in Volkspark Humboldthain: three of the seven storeys of the largest bunker complex in Berlin, crossed on unsupported walkways over open drops. The tower, roughly 70 by 70 metres and about 40 metres tall, went up between 1940 and 1942; its north face survived demolition only because the railway line beside it had to be spared. By 1950 some 1.4 million cubic metres of rubble had been heaped over the site.
Adults only – strictly 18 and over. May to October only; the tour does not run from November to April. About 10 °C even in high summer, high humidity, helmets compulsory and provided, shoes inspected at the door. English departures existed on 17 days of the 30-day window. The viewing platform on top of the tower, by contrast, is free and open at any hour.
€18 (about $20.63), reduced €13, about 90 minutes, online only
Berliner Unterwelten: Subways, Bunkers, Cold War (formerly Tour 3)
The east–west conflict underground, told inside the Blochplatz complex at Gesundbrunnen: a U-Bahn structure converted to a shelter during the war and patched back into service as a civil-defence bunker in 1981–83. Themes are the fear of the bomb, the airlift, the Wall, the Rudow spy tunnel, escapes through the sewers and the ghost stations, with a model atomic bomb and a walk-through sewer pipe.
For anyone more drawn to the Cold War than to the Second World War. Minors only with a parent or guardian. Note the change: the Pankstraße nuclear bunker used to be part of this tour and has been a separate one since May 2026. English departures on 18 days of the 30-day window.
€18 (about $20.63), reduced €13, about 90 minutes, online only
Berliner Unterwelten: Nuclear Bunker Pankstraße (new since May 2026)
A multi-purpose shelter built into Pankstraße U-Bahn station in the 1970s and listed as a monument since 2010: more than 3,000 people were meant to hold out here for two weeks, with their own waterworks, reinforced concrete doors, filtered ventilation and emergency power. The tour runs the line from Cold War civil defence to the arguments Germany is having about shelters now.
The newest tour in the programme, and the one that answers the question of whether Berlin still has shelters at all. The dormitories of four-tier bunks are the bleakest room on any of the standard tours. Meeting point is Badstraße 50, in front of St Paul's church – not Brunnenstraße. English departures on 14 days of the 30-day window, and also sold in French, Spanish, Dutch and Danish.
€18 (about $20.63), reduced €13, about 90 minutes, online only
Berliner Unterwelten: Under the Berlin Wall (escape tunnels, Bernauer Straße)
The story of the tunnels dug under the Berlin Wall, told beside the street where most of the digging happened. The centrepiece is a view into the only surviving original escape tunnel, from 1970/71, nine metres down, reached through a 30-metre visitor tunnel the association built itself. The association counts more than 75 known escape tunnels, 19 of which worked; up to 450 people got out through them.
The best-served tour in English alongside Dark Worlds – 90 English departures across 26 days in the window checked. Pairs naturally with the free Berlin Wall Memorial next door on Bernauer Straße. Recommended from about age 16. There are occasional dated departures with eyewitnesses: former escape helpers and people who fled.
€18 (about $20.63), reduced €13, about 90 minutes, online only
Berliner Unterwelten: The Fichtebunker Kreuzberg
A high-rise bunker built inside a 19th-century gasholder: six floors, 600 rooms, designed for 6,000 people, fitted out in 1941/42 with passenger lifts, ventilation and heating – air-raid protection as propaganda. After the war it served as refugee accommodation, a juvenile prison, an old people's home and a homeless shelter, before becoming a strategic food store for West Berlin.
Architecture and social history rather than military hardware, and the post-war chapters are as strong as the wartime ones. Far fewer stairs than the Gesundbrunnen tours, though still not step-free. Cold – bring a jacket. English departures on only four days of the 30-day window, so this one needs planning.
€18 (about $20.63), reduced €13, about 90 minutes, online only
Berliner Unterwelten: The AEG Tunnel
Germany's first underground railway tunnel: 295 metres long, in service from 31 May 1897, linking two AEG factory sites in Wedding with electric trains. It made munitions in the First World War and sheltered factory workers in the Second, then stood flooded for years until the association began restoring it in 2016. Used as a location in the television series Babylon Berlin.
The only tour in the programme with no war at its centre – this is industrial and transport history. Age 14 and over. About 10 °C all year. Important for English-speaking visitors: this tour is sold in German only, and there were no English dates at all in the booking window checked. Departures are rare even in German, so book on release day.
€18 (about $20.63), no reduced rate, about 90 minutes, online only
Berliner Unterwelten: Tunnel and Bunker Dresdener Straße
A U-Bahn tunnel about 450 metres long, with the shell of a station, built under Kreuzberg and Mitte before the First World War and in the 1920s and never used. Parts were converted into a shelter under the Nazis: everyone sheltering here survived the great raid of 3 February 1945. From 1961 the border ran straight through the structure, and East Germany installed barriers underground.
For people who have already done a standard tour. Groups are capped at 20, which is why it sells out first – there were English departures on only four days of the 30-day window. Age 14 and over. The harder version, Dresdener Straße Special, is 18-plus and takes you in waders with a torch into the flooded, unlit section; it had exactly one English date, on 8 October 2026, with a cap of 16 people.
€18 (about $20.63), no reduced rate, about 90 minutes, online only
Berliner Unterwelten: Operating Theatre Bunker Teichstraße
The surviving surgical bunker of the former Humboldt Hospital in Reinickendorf, built so that emergency operations could continue during air raids. It later served as a civil-protection store.
Medical history, and the only structurally step-free tour the association runs. Age 14 and over. German only: there were no English departures in the booking window checked, and there is no English page for it on the association's site.
€18 (about $20.63), no reduced rate, about 70 minutes, online only
Berliner Unterwelten: Humboldthain Spezial and Humboldthain Extrem
Multi-hour expeditions into the sealed parts of the flak tower ruin, with a helmet, your own powerful torch and ankle-high boots with a grip sole. Spezial lasts about 2.5 hours and goes in through two shafts 60 cm across. Extrem lasts about 3 hours.
18 and over, fit enough for mountain walking, and – this matters for visitors from abroad – German language skills are a condition of entry for insurance reasons, so Humboldthain Spezial cannot be booked in English. No participation over two metres tall on Spezial, and none with a recognised disability. Closed November to April. Extrem is not on sale at all at present while the structure is made safe (as of 09/2026).
Spezial €55 (about $63.03), Extrem €65 (about $74.49), online only
Berlin Story Bunker (Anhalter Bahnhof)
A privately run museum inside the Reichsbahn high-rise air-raid bunker of 1942 by Anhalter Bahnhof. The main part is the documentation "Hitler – how could it happen": more than 3,000 square metres on three floors, 38 themed sections from the rise of the Nazi party to the end in the Führerbunker, with a model of the Führerbunker at 1:25. The same ticket covers "Germany 1945 to today" and the Ukraine Museum in the same building.
For anyone who wants to stand inside a bunker without a booking, a guide or a fixed time – open 10:00 to 19:00, 365 days a year. Very text-heavy: the operator reckons on two to three hours, audio guide in 12 languages, exhibition texts in German and English. No photography (house rules, clause 8). Not suitable for wheelchairs. This is not the Führerbunker, which is 1.5 km away and not accessible, and it is not The Story of Berlin either.
€18 (about $20.63), reduced €12 (about $13.75), card payment only
The Führerbunker site (Gertrud-Kolmar-Straße / In den Ministergärten) – nothing to enter
The command bunker where Hitler spent his last months stood under the garden of the old Reich Chancellery. Soviet engineers demolished what they could in 1947, East Germany took out more in the 1980s, and the remaining voids were filled during the redevelopment of the 1990s. Since 8 June 2006 a single information board with a plan of the complex has stood at the corner of Gertrud-Kolmar-Straße and In den Ministergärten.
What you actually see is a car park between apartment blocks and one sign. That is deliberate: the city, advised by historians, chose not to create a pilgrimage site. It is about five minutes on foot from Potsdamer Platz and next to the Memorial to the Murdered Jews of Europe. Every product sold online as a Führerbunker tour is a street-level walk that stops at this board.
free, open at any hour
Tempelhof Airport: the "Hidden Places" tour
A two-hour walk through the cellars, air-raid rooms and tunnels of the airport building, including the film bunker that burned out at the end of the war and the traces left by the US Air Force and by intelligence work during the Cold War.
The obvious plan B when Berliner Unterwelten is full – and the one large bunker tour in Berlin where you may take photographs for private use, and where children from 6 pay the reduced rate. Runs in English as well as German; the English page lists Saturdays at 10:30 plus extra September dates, the German schedule is far denser. Book online or at the visitor centre (card only), about four weeks ahead; there are no leftover tickets on site for sold-out dates and the minimum group size is 8. Closed shoes and reasonable fitness required; no wheelchairs, walking frames, pushchairs or animals. From late October there is a torchlight tour for families (age 10 and up, 90 minutes).
€17.50 (about $20.05), reduced €12, 25 per cent off with a Berlin WelcomeCard
Spandau Citadel (casemates and bat cellar)
One of the best-preserved Renaissance fortresses in Europe, with bastions, vaults and the medieval Julius Tower. What draws underground visitors are the fortress vaults and the bat cellar in Building 4, an enclosure holding around 200 tropical fruit bats and bats.
For families and for anyone who wants to turn up without a guide and without a booking – by far the cheapest entry on this page. Friday to Wednesday 10:00–17:00, Thursday 13:00–20:00; the bat cellar daily 12:00–17:00. The bat-themed tours run by the Berliner Artenschutz Team (BAT e.V.) happen irregularly, from 4 September in 2026, and need a phone booking.
€4.50 (about $5.16), reduced €2.50, including all museums and the Julius Tower, per Visit Spandau
Fort Hahneberg (Spandau-Staaken)
A Prussian artillery fort built between 1882 and 1888, with long casemates and connecting passages. Later quarried for stone, it lay inside the Berlin Wall death strip from 1961 and grew wild – today it is both a listed monument and a refuge for plants and animals.
Lost-place atmosphere that works with children and carries none of the horror of the war sites. Guided visits only, run by volunteers of ASG Fort Hahneberg: Saturdays at 14:00 and 16:00 until the end of October, maximum 25 people, tickets in advance at fbs.forthahneberg.de. Sturdy shoes required, torch recommended. The association also runs its own bat and nature walks. This is the one site on the page that is genuinely easier by car.
€9.50 (about $10.89), children 6–16 €5, family €25; under-6s free
Prenzlauer Berg water reservoirs (events only)
Two underground reservoirs from Berlin's first public water supply, built between 1852 and 1856 and later extended, under the hill by the water tower. The large reservoir is a set of concentric ring vaults with a reverberation of up to 20 seconds; inside it is 8–10 °C, and no more than 99 visitors are allowed in each reservoir.
There is no regular visiting at all – the vaults open for art and sound events and for occasional guided walks. The long-standing stewardship by Förderband e.V. ended on 31 December 2025 and the Pankow district culture office has taken over. The association unter-berlin e.V. runs walks called "Prenzlauer Berg from below", with dates in 2026 including 5 September and 3 October, booking requested.
varies by event
The Story of Berlin and the Ku'damm nuclear shelter – CLOSED
The multi-purpose shelter built under the Ku'damm-Karree in 1973/74 for 3,592 people, with supplies and diesel for 14 days, was for years the finale of a visit to The Story of Berlin museum.
Status as of September 2026: the museum is closed while the building complex is rebuilt under the new name FÜRST, and both berlin.de and visitBerlin list it as closed with no reopening date. German Wikipedia says the exhibition has been dark since early 2019; announced reopenings, first for 2020 and then for 2026, remain unconfirmed. English listings still sell it with old prices and hours. If you want to see a nuclear shelter, book Nuclear Bunker Pankstraße instead.
no visits possible
Tickets and prices
Berliner Unterwelten releases tickets exactly 30 days before the date, in its own shop at tickets.berliner-unterwelten.de, and nowhere else. The association's English FAQ puts it plainly: "Tickets for English guided tours are available via our Online-Shop. No ticket sales at the meeting point. Tickets are available up to 30 days in advance and excluded from exchange, refund and return." There is no box office at the meeting points, none at the Info and Bookshop, and no authorised resale through other platforms. Money comes back only if the association cancels the tour. Tempelhof opens booking about four weeks ahead, online or at the CHECK-IN visitor centre (card payment only), with no cancellation. Fort Hahneberg sells in advance through fbs.forthahneberg.de. The Berlin Story Bunker needs no booking at all: you turn up and pay at the desk.

When everything is sold out
The English-language dates that go first are the ones with small groups and few departures: Tunnel and Bunker Dresdener Straße (maximum 20 people, eight English slots on four days in the 30-day window checked on 20 September 2026), the Fichtebunker (also eight slots on four days) and Dresdener Straße Special (a single English date in the whole window, 8 October, maximum 16 people). Dark Worlds and Under the Berlin Wall are the opposite case: each had around 90 English slots spread over 26 of the 30 days. That does not mean seats are free – on the day this page was checked, all four English Dark Worlds departures and all six German ones were already marked as booked. At Tempelhof, sold-out dates mean sold out: the operator states expressly that no remaining tickets are sold on site. The joint Tempelhof–Unterwelten special "Bunkermythen debunked" was fully booked for every autumn 2026 date.
Tours of underground Berlin
Berliner Unterwelten sells its own tickets and nobody else's: €18 (about $20.63) in its shop, released exactly 30 days ahead, with no box office at the door. No reseller can get you into those bunkers, so anything advertised as a Berliner Unterwelten ticket is worth reading twice. A reseller earns its keep elsewhere – at the Berlin Story Bunker, where €18 buys you in any day and a booked slot saves the queue, and on the guided walks that cover Third Reich Berlin above ground. Two things to check in the description: whether admission is actually included, and whether a tour sold as a Führerbunker tour goes anywhere underground – every one of them stops at an information board on a car park, which is free.

Opening hours and best time
Berliner Unterwelten has no opening hours in the usual sense: every tour runs on fixed dates in the booking calendar. The Info and Bookshop at Brunnenstraße 105 is open daily 10:00–15:30 but sells no tour tickets at all. Flak tower tours pause from November to April; there are closing days and a special programme around Christmas and New Year. The "Myth of Germania" exhibition opens on Saturdays only, 11:00–17:00, last entry 16:00. Berlin Story Bunker: every day of the year, 10:00–19:00, last admission 17:30. Tempelhof Airport, "Hidden Places": the German-language tour runs Monday, Wednesday, Thursday and Friday at 11:00 and Saturday and Sunday at 11:00 and 11:30, with an extra 14:00 slot from 2 to 28 September 2026; the English page lists the tour on Saturdays at 10:30, with additional afternoon dates on 21, 23 and 28 September 2026. No Tempelhof tours on Tuesdays; the CHECK-IN visitor centre is open Wednesday to Monday 10:00–17:00. Spandau Citadel: Friday to Wednesday 10:00–17:00, Thursday 13:00–20:00, last entry 30 minutes before closing. Fort Hahneberg: guided tours on Saturdays at 14:00 and 16:00 until the end of October. The Story of Berlin on Kurfürstendamm is closed.
When it is quietest
Weather is irrelevant below ground, with one large exception: the flak tower tours in Volkspark Humboldthain pause from November to April, so the inside of that building is a May-to-October proposition. Fort Hahneberg also stops at the end of October. For booking comfort, weekdays outside the German school holidays are calmest; weekend dates and the English departures are the ones to grab the day they appear, 30 days ahead. The Berlin Story Bunker is emptiest right at 10:00, and you want that head start: with the last admission at 17:30 you would have 90 minutes for an exhibition the operator reckons takes two to three hours.
Who it suits
With children
Berliner Unterwelten admits nobody under 7 on any tour. Between 7 and 13 it is the parents' decision, and the association recommends the tours from about age 14. Under the Berlin Wall is recommended from about 16, the Teichstraße operating theatre bunker from about 17. Better options with younger children are the Tempelhof torchlight tour (age 10 and up, accompanied), Fort Hahneberg (under-6s free, bring a torch) and Spandau Citadel with its bat cellar.
Minimum age
Berliner Unterwelten: 7 across the board; 14 for the AEG Tunnel, Tunnel and Bunker Dresdener Straße and the Teichstraße bunker, with minors accompanied by a parent or guardian; 18 for every flak tower tour and for Dresdener Straße Special. ID can be checked at the door. The Berlin Story Bunker publishes no minimum age, but the photographs and film of the war and the Holocaust are graphic and it is not a place for younger children.
Wheelchair
Poor. Berliner Unterwelten states outright that its tours and exhibitions are not accessible, and the only structurally step-free tour in the programme is the Teichstraße operating theatre bunker. Everything else means numerous, sometimes steep stairs and 90 minutes on your feet with nowhere to sit. The Berlin Story Bunker says it is not suitable for wheelchairs. Tempelhof does not allow wheelchairs, walking frames or pushchairs on its tours.
Pushchair
Not possible on any of the guided tours. Berliner Unterwelten also bans bags larger than a handbag or a small rucksack – there are lockers in Gesundbrunnen station.
Dogs
Berliner Unterwelten and Tempelhof do not allow animals (guide dogs excepted). The Berlin Story Bunker allows assistance dogs only.
Claustrophobia
The standard tours run through rooms you can stand up in; what gets to people is usually the subject matter rather than the space – the dormitories of four-tier bunks in the Pankstraße nuclear shelter are the bleakest room in the regular programme. It only gets genuinely tight on Humboldthain Spezial, which enters through two shafts 60 cm across; the association rules it out for anyone claustrophobic, for very heavy visitors and for anyone over two metres tall.
What to wear
Sturdy, fully enclosed shoes are a condition of entry on every Berliner Unterwelten tour – no sandals, flip-flops, ballet flats or heels. Footwear is checked at the flak tower door, and helmets are handed out there. Bring a jacket even in August: the flak tower, the AEG tunnel, the Fichtebunker and the escape-tunnel site sit at 8–14 °C all year, the flak tower at about 10 °C. Tempelhof also requires closed, sturdy shoes and takes you outdoors for part of the route; Fort Hahneberg wants sturdy shoes and suggests a torch. There are no visitor toilets on any Berliner Unterwelten tour.
Photography
Both of the big bunker visits ban it. Berliner Unterwelten: "Photography, filming and sound recordings are generally not permitted", and that extends to smart glasses unless they are switched off and stowed. The Berlin Story Bunker's house rules say the same in their eighth clause. The one major underground tour in Berlin where you may photograph freely for private use is Tempelhof, where tripods are allowed only on the dedicated photo tour.
Getting there
By public transport
From BER airport, the fastest way in is the FEX airport express: about 14 minutes to Südkreuz, 19 to Potsdamer Platz and 23 to Berlin Hauptbahnhof, every 15 to 30 minutes. The S9 and the RE7, RE8 and RB14 regional trains also run into the city. The airport lies in fare zone C, so you need an ABC ticket (€5.00, about $5.73); everything on this page except Fort Hahneberg is inside zones AB. Once you are in town, almost every meeting point is on a U-Bahn platform. Gesundbrunnen (S1, S2, S25, S26, S41, S42, U8, regional trains, bus 247) is the start for Dark Worlds (Brunnenstraße 105), for Subways/Bunkers/Cold War (Badstraße at Böttgerstraße) and for the flak tower on the lower platform of the ruin in Volkspark Humboldthain. Nuclear Bunker Pankstraße: U8 Pankstraße, meeting at Badstraße 50 in front of St Paul's church. The AEG Tunnel: U8 Voltastraße, six minutes on foot. Under the Berlin Wall: U8 Bernauer Straße, Brunnenstraße 141. Dresdener Straße: U8 Heinrich-Heine-Straße or Moritzplatz, about eight minutes. Fichtebunker: U7 Südstern, five minutes. Teichstraße: U8 Paracelsus-Bad. Berlin Story Bunker: Schöneberger Straße 23A by S-Bahn Anhalter Bahnhof. Tempelhof: U6 Platz der Luftbrücke, meeting at the CHECK-IN visitor centre. Spandau Citadel: U7 Zitadelle.
By car
Do not plan on driving. The association advises public transport for every one of its tours: parking around Gesundbrunnen, Wedding, Kreuzberg and Mitte is scarce, and there is none at all at the AEG site or at Pankstraße. Berlin also charges a fee for on-street parking across the whole inner city. The only two sites on this page a hire car genuinely helps with are Fort Hahneberg in Staaken and Spandau Citadel, both far out to the west.
From the nearest city
Everything is inside Berlin, and almost all of it is on one line. The U8 threads the association's sites together in order – Paracelsus-Bad, Pankstraße, Gesundbrunnen, Voltastraße, Bernauer Straße, Heinrich-Heine-Straße, Moritzplatz – so two tours in a day is easy to arrange. Is the Berlin WelcomeCard worth it for this? Only sideways. It buys you nothing on the Berliner Unterwelten tours, which is where most of your money goes; it does cut 25 per cent off Tempelhof and, per the card's own partner page, 25 per cent at the Berlin Story Bunker. Buy it for the transport if you are also using the card elsewhere, and choose ABC if you are arriving at BER.
Tips for your visit
- Set an alarm for the release. Berliner Unterwelten tickets appear exactly 30 days ahead and only in the association's own shop. Turning up at Gesundbrunnen on the day gets you nothing – not at the meeting point, not in the bookshop.
- Check the date three times before you pay. Tickets cannot be exchanged, rebooked or returned, whatever happens to your flight or your health. Refunds exist only when the association cancels.
- Take the shoe rule literally. Sandals, flip-flops, ballet flats and heels are turned away at the door with no refund, and footwear is actively inspected at the flak tower.
- If you only speak English, choose your tour before you fall in love with one. Dark Worlds and Under the Berlin Wall run in English almost daily; the Fichtebunker and Dresdener Straße run in English about one day a week; the AEG tunnel, the Teichstraße operating theatre bunker and Humboldthain Spezial do not run in English at all.
- Use the toilet first and travel light. There are no visitor toilets on any tour, and bags bigger than a small rucksack are refused – there are lockers in Gesundbrunnen station.
- Read the meeting point, not the address of the association. Pankstraße, Bernauer Straße, Voltastraße, Dresdener Straße, Fichtestraße and Teichstraße each have their own starting point, several U-Bahn stops away from Brunnenstraße.
- Everything sold out? Plan B without a booking is the Berlin Story Bunker, open every day. Plan C with a guide is Hidden Places at Tempelhof, which usually has dates left – and it is also the only one of them where you may take photographs.
- Get to the Berlin Story Bunker by 15:00 at the latest. Arriving at the 17:30 last admission leaves 90 minutes for an exhibition the operator reckons takes two to three hours. Card payment only, and no photography inside.
- Two tours in one day works well along the U8, but leave an hour between them and do not stack two wartime tours: they overlap, and three hours standing on concrete is more tiring than it sounds.
What the internet gets wrong
Nothing sold under those headings takes you inside, because there is no inside. Soviet engineers demolished what they could in 1947, East Germany removed more in the 1980s, and the remaining voids were filled with sand and concrete during the redevelopment of the 1990s. Since 8 June 2006 the site has carried one information board at the corner of Gertrud-Kolmar-Straße and In den Ministergärten, and the ground above it is a residential car park. Every "Führerbunker tour" is a street-level walk that stops at that board, and the board itself is free and open at any hour.
Three things wrong on one page. The building is an original Reichsbahn air-raid bunker of 1942 by Anhalter Bahnhof, not a replica of anything; what it holds of the Führerbunker is a model at 1:25 and a reconstructed room. There is no guided tour and no booking – you walk in, 10:00 to 19:00, every day of the year. And the ticket is €18 (about $20.63), reduced €12, card payment only, covering all three exhibitions. Sites that go the other way are just as wrong: berlin-escape.com quotes "around €14.50 exhibition, €19.50 combined with bunker tour" and says "Guided tours of the actual bunker structure run several times daily and must be booked separately" at "approximately 45 minutes", while berlin-tickets-tours.com sells a "Skip-the-Line" ticket to a museum that has no queue system and promises "800 YEARS OF BERLIN'S HISTORY" with "Over 50 multimedia stations" – an exhibition that is not among the three the operator lists.
Every public Berliner Unterwelten tour costs the same €18 (about $20.63). The booking system returns 1800 cents for the standard ticket and 1300 for the reduced one. The reduced €13 exists on the six main tours only – the AEG tunnel, Dresdener Straße and Teichstraße have no concession – and pensioners do not qualify for it anywhere.
Tour M is not Dark Worlds. The association's own ticket shop still labels the escape-tunnel tour "Tour M (English) – Under the Berlin Wall", and it has dropped the old numbers and letters from its marketing anyway. On 20 September 2026 eight tours were on sale in English, not four: Dark Worlds, Under the Berlin Wall, Subways/Bunkers/Cold War, From Flak Towers to Mountains of Debris, Nuclear Bunker Pankstraße, The Fichtebunker Kreuzberg, Tunnel and Bunker Dresdener Straße and Dresdener Straße Special. "Daily" is only true of the first two, which had 89 and 90 English departures spread over 26 of the next 30 days. The Fichtebunker and Dresdener Straße had eight English slots each, on four days. Dresdener Straße Special had one. And three tours have no English at all: the AEG tunnel, the Teichstraße operating theatre bunker and Humboldthain Spezial, the last of which requires German for insurance reasons.
Neither is true, and this is the misconception most likely to cost you an argument at the door. Berliner Unterwelten's English rules read "Photography, filming and sound recordings are generally not permitted", and the ban extends to smart glasses unless they are switched off and stowed. The Berlin Story Bunker's house rules say the same in clause 8. The one large underground tour in Berlin where private photography is allowed is Hidden Places at Tempelhof, where even there tripods are restricted to the dedicated photo tour.
There is no ticket counter anywhere. The association's English FAQ states it directly: tickets are sold in the online shop only, are released up to 30 days in advance, and there are no sales at the meeting point. The Info and Bookshop is open 10:00–15:30 and sells books. The single exception in the whole operation is the Saturday-only "Myth of Germania" exhibition, where €6 is taken at the door in cash, in the exact amount, with no card accepted.
There is nothing ghostly left to visit. The ghost stations were the stations on the three U-Bahn and S-Bahn lines that ran from one part of West Berlin to another through East Berlin between 1961 and 1989, where the trains slowed but never stopped. They went back into normal service as the border opened in 1989 and 1990, and today they are ordinary working stations you ride through for the price of a €4.00 ticket. What a tour can actually show you is the Cold War shelter at Blochplatz on the Subways/Bunkers/Cold War tour; what explains them properly is the free Berlin Wall Foundation exhibition on the mezzanine of Nordbahnhof S-Bahn station, captioned in German and English. The same page also has the Pankstraße bunker as a stop on the Gesundbrunnen tour, which it stopped being in May 2026, and says "Prices vary by tour" when they do not.
April to end of October only (closed Nov–March for bat hibernation)" for the Humboldthain flak tower (berlintourism.org): the association's winter break runs from November to April, so the inside of the tower is open from May to October, not from April. The first English flak tower dates in the 2026 calendar fall in April, which is where the confusion comes from, but the German schedule is the one to plan against. No operator page gives bats as the reason for the break, and the same applies to Fort Hahneberg, which also stops at the end of October without saying why. The tower's outdoor viewing platform, by contrast, really is open all year and free.
History in brief
- Berlin's underground is young. Sand and a high water table ruled out medieval catacombs, so nearly everything you can visit dates from industrialisation onwards: brewery cellars, the water reservoirs of 1852–1856, pneumatic post, sewers and the U-Bahn.
- In 1897 AEG opened a 295-metre works tunnel in Wedding with an electric railway running through it – the association calls it the first underground railway tunnel in Germany.
- During the Second World War, U-Bahn structures such as the one at Gesundbrunnen were built out into air-raid shelters. From September 1940 Hitler ordered flak towers planned, and between autumn 1940 and spring 1942 three pairs went up in Berlin, one of them in Volkspark Humboldthain. The Fichtebunker of 1941/42 and the Reichsbahn bunker by Anhalter Bahnhof of 1942 – today's Berlin Story Bunker – come from the same wave of building.
- After 1945 the Allies blew up most of the bunkers. The north face of the Humboldthain tower stayed standing because the railway line beside it could not be damaged, and by 1950 the ruin had been buried under some 1.4 million cubic metres of rubble. The Gesundbrunnen complex survived for the same kind of practical reason: demolition would have endangered the U-Bahn tunnel.
- The Wall of 1961 divided the underground too: ghost stations, grilles across the sewers, barriers inside the Dresdener Straße tunnel. Between 1961 and 1982, according to Berliner Unterwelten e.V., more than 75 escape tunnels were dug and 19 of them worked.
- The Cold War left West Berlin with multi-purpose shelters such as Pankstraße (1970s, more than 3,000 places) and Ku'damm-Karree (1973/74, 3,592 places). In 1989 West Berlin had 16 public shelters with room for about 24,600 people between them – roughly one per cent of the population.
- Berliner Unterwelten e.V. was founded in 1997 and rediscovered the Gesundbrunnen complex in 1998. It has guided visitors through the flak tower since April 2004, the AEG tunnel since 2016 and the Pankstraße nuclear bunker since May 2026, and received Germany's national monument-preservation prize, the Silberne Halbkugel, in 2006.
- Civil defence became a live political subject again after the Russian attack on Ukraine in 2022, which is the background both to the new Pankstraße tour and to the Ukraine Museum that opened in the Berlin Story Bunker in February 2026.
Frequent questions
Can you visit Hitler's bunker in Berlin?
No. The Führerbunker was demolished in stages from 1947 onwards and the last voids were filled during the redevelopment of the 1990s. The site at Gertrud-Kolmar-Straße and In den Ministergärten, about five minutes' walk from Potsdamer Platz, is a residential car park with one information board installed on 8 June 2006. Nothing is sold that gets you underground there; a ticket advertised as a Führerbunker tour is a walking tour that stops at the board. The closest you get to the rooms themselves is the 1:25 model and the reconstructed study in the Berlin Story Bunker, 1.5 km away.
Is the Berlin Story Bunker the Führerbunker?
No, and they are 1.5 km apart. The Berlin Story Bunker is an original Reichsbahn air-raid bunker of 1942 by Anhalter Bahnhof, built for railway passengers. Inside it is the documentation "Hitler – how could it happen", more than 3,000 square metres across three floors, which ends with a model of the Führerbunker. It is also not The Story of Berlin, a different museum with a different owner on Kurfürstendamm, which has been closed since early 2019 and has no reopening date.
Do Berliner Unterwelten tours run in English, and how often?
Eight tours were on sale in English on 20 September 2026. Dark Worlds and Under the Berlin Wall run almost every day, with around 90 English departures each across the next 30 days. Subways/Bunkers/Cold War had 51, the flak tower 32 and Nuclear Bunker Pankstraße 22. The Fichtebunker and Tunnel and Bunker Dresdener Straße had eight English slots each, spread over four days, and Dresdener Straße Special had a single date. Three tours run in German only: the AEG tunnel, the Teichstraße operating theatre bunker and Humboldthain Spezial, which requires German for insurance reasons. Dark Worlds also runs in French, Spanish, Italian, Dutch and Danish.
How do I get Berliner Unterwelten tickets, and can I buy them on the day?
Online only, at tickets.berliner-unterwelten.de, and nowhere else. Tickets go on sale exactly 30 days before the date. There is no box office at any meeting point and none in the Info and Bookshop, and no other platform is authorised to sell them. Tickets cannot be exchanged, rebooked or refunded; you get your money back only if the association cancels. Older guides telling you to queue at a ticket booth in the morning are describing a system that no longer exists.
How much do Berlin bunker tours cost in 2026?
Every public Berliner Unterwelten tour is €18, about $20.63 at the European Central Bank rate of 18 September 2026. Six of them have a €13 concession for students, trainees, disabled visitors and people on benefits, with proof; the AEG tunnel, Dresdener Straße and Teichstraße have none, and pensioners never qualify. The flak tower specials are €55 and €65. The Berlin Story Bunker is €18, reduced €12, for everything in the building. Hidden Places at Tempelhof is €17.50, reduced €12. Spandau Citadel, at €4.50, is the cheapest underground visit in the city. Prices of €13.50, €15, €16 or €17 on English sites are all out of date.
How long does a Berlin bunker tour take, and how many steps are there?
The standard Berliner Unterwelten tours run 90 minutes; the Teichstraße bunker is about 70 minutes, the flak tower specials 2.5 to 3 hours, Hidden Places at Tempelhof about 2 hours. The association does not publish step counts, but every tour except Teichstraße involves numerous and sometimes steep stairs, and you are standing or walking for the full 90 minutes with nowhere to sit and no toilets. The Berlin Story Bunker is self-paced and the operator reckons two to three hours.
Can you visit a Berlin bunker without a tour?
Yes, but only in a few places. The Berlin Story Bunker is open every day from 10:00 to 19:00 with no booking and no guide, and it is the obvious answer when everything else is sold out. Spandau Citadel lets you into the fortress vaults and the bat cellar on an ordinary ticket. The Saturday-only "Myth of Germania" exhibition at Gesundbrunnen is also self-guided. Everything run by Berliner Unterwelten underground, and everything at Tempelhof and Fort Hahneberg, is guided-tour-only.
Can you take photos on a Berlin bunker tour?
Not on the two you are most likely to book. Berliner Unterwelten bans photography, filming and sound recording on every tour, smart glasses included, and the Berlin Story Bunker bans it in its house rules. Hidden Places at Tempelhof is the exception: photography for private use is allowed there, with tripods restricted to the separate photo tour. Plan to remember the Gesundbrunnen shelter rather than to photograph it.
Is the Berlin WelcomeCard worth it for the bunkers?
Only for the transport and the smaller sites. The card is expressly not valid on Berliner Unterwelten tours – the association says it counts only towards the "Myth of Germania" exhibition – and that is where most of your admission money goes. It does give 25 per cent off the Tempelhof tours and, according to the card's own partner page, 25 per cent off the full-price ticket at the Berlin Story Bunker, applied at the desk. The 48-hour card is €28.50 for zones AB and €34.50 for ABC, and you need ABC if you are arriving at BER.
Are the tours suitable for children?
Berliner Unterwelten takes nobody under 7 on any tour, leaves ages 7 to 13 to the parents' judgement, and recommends the tours from about 14. The AEG tunnel, Dresdener Straße and Teichstraße are 14 and over; all flak tower tours are 18 and over. The Berlin Story Bunker sets no age limit but shows graphic material on the war and the Holocaust. For younger children the better choices are the Tempelhof torchlight tour (age 10 and up, from late October), Fort Hahneberg on a Saturday, and the bat cellar at Spandau Citadel.
Can you visit Berlin's ghost stations?
There are none left to visit. Between 1961 and 1989, three U-Bahn and S-Bahn lines carried West Berlin passengers under East Berlin past stations that were sealed and guarded, and the trains slowed without stopping. Those stations reopened as the border came down in 1989 and 1990 and are ordinary working stations today – you pass through several on a €4.00 ticket. The free exhibition "Border Stations and Ghost Stations in Divided Berlin", on the mezzanine of Nordbahnhof S-Bahn station, tells that story with English captions, and the Subways, Bunkers, Cold War tour covers it underground.
What should I wear, and how cold is it?
Sturdy, fully enclosed shoes are a condition of entry on every Berliner Unterwelten tour, checked at the door for the flak tower, and Tempelhof requires the same. Bring a jacket whatever the month: the flak tower, the AEG tunnel, the Fichtebunker and the escape-tunnel site sit between 8 and 14 °C all year, and the flak tower is around 10 °C in August. Helmets are provided where they are needed. Leave big bags at the hotel or in the lockers at Gesundbrunnen station.
What do I do if everything is sold out?
Walk into the Berlin Story Bunker – no booking, open every day, one ticket for three exhibitions. If you want a guide, try Hidden Places at Tempelhof, which releases about four weeks ahead and usually has more availability, or Fort Hahneberg on a Saturday afternoon. Then keep checking the Berliner Unterwelten shop: dates enter the calendar on a rolling 30-day release, so a day that shows nothing this week may open next week.
How do I get from BER airport to the tours?
The FEX airport express takes about 14 minutes to Südkreuz, 19 to Potsdamer Platz and 23 to Berlin Hauptbahnhof; the S9 and the RE7, RE8 and RB14 regional trains are slower but reach other parts of the city directly. BER is in fare zone C, so you need an ABC ticket at €5.00. From Hauptbahnhof, the S-Bahn ring takes you to Gesundbrunnen in a few minutes, and the U8 links almost all of the association's meeting points in one line. For the Berlin Story Bunker, get out at Anhalter Bahnhof; for Tempelhof, U6 to Platz der Luftbrücke.
