About three miles of tunnel run on five levels through the chalk under Dover Castle – cut in 1797–98 as an underground barracks against Napoleon, and extended in the Second World War into a command centre, a hospital and finally a nuclear bunker. From the Casemate level Vice-Admiral Bertram Ramsay ran Operation Dynamo at the end of May 1940, the evacuation of 338,226 men from Dunkirk. Plan around one thing: on 20 September 2026 English Heritage still carried the notice that the Operation Dynamo section is closed for essential maintenance, while its own Dover Castle FAQ page insisted the opposite. What you can actually walk in 2026 is the Underground Hospital, on its own guided tour, and the medieval Spur tunnels, which need no guide at all.

The four levels under the castle, compared
Secret Wartime Tunnels – Operation Dynamo (Casemate level)
The level from which Vice-Admiral Bertram Ramsay directed the Dunkirk evacuation at the end of May 1940: seven casemates of 1797/98, partitioned in the Second World War into signals, planning and briefing rooms. The tour is part led by staff, part staged – original recordings, radio bulletins and light and sound effects in the reconstructed naval headquarters and the coastal artillery operations room.
The point that decides your visit in 2026: this section is closed for essential maintenance and English Heritage gives no reopening date. Independent guiding is banned here in any case.
included in admission
Underground Hospital (Annexe level)
The underground hospital, driven into the chalk in 1941/42 as a dressing station and quarters for the combined headquarters: three east–west galleries with two rows of eight tunnels between them, used as wards and dormitories. Today you walk through the operating theatre, the wards and the corridors, staged with sound and smell.
Open in September 2026 – the part of the wartime tunnels you can actually see right now. Not accessible by wheelchair or mobility scooter; there are steep stairs at the exit, with a lift as the alternative.
included in admission
Medieval tunnels – the Spur tunnels under the northern outworks
The oldest passages on the site. After the sieges of 1216 and 1217, when the breached north gate was blocked up, Henry III's masons drove a tunnel under the outer wall to the new St John's Tower and on beneath the outwork, where it split three ways. In the Napoleonic period the passages were enlarged against a French landing. They now form part of the Dover Castle Under Siege exhibition, with sound and light installations, and come out at the new viewpoint on the northern Spur.
Access only by a narrow spiral stair: 18 steps down, 26 up at the end, with a handrail. The Spur casemates with the siege exhibition and the viewpoint are step-free; if you would rather not go down, a virtual tour of the tunnels runs in the casemates.
included in admission
Dumpy – the Cold War government bunker
Deep Underground Military Position Yellow, cut about 50 metres below the surface in 1942/43 as the combined headquarters of army, navy and air force, with its own operations rooms and a large telephone exchange; part of the preparation for the Normandy landings and for the deception Operation Fortitude South ran from here. In the early 1960s Dumpy became the core of one of twelve Regional Seats of Government for a nuclear war, with a filtration plant, dormitories on the Annexe level and a small broadcasting studio. It was stood down in the early 1980s.
The tour last ran in the winter of 2024/25, with tickets sold on site on the day only, age 18 and over, and not recommended for anyone with asthma, respiratory problems or a fear of confined spaces; in an emergency you have to climb 80 steps unaided, because the lift stops. Whether dates return in 2026/27 is open.

Tickets and tours for Dover Castle
Booking direct with English Heritage is almost always cheaper: online saves 15%, the tunnel tours are included in admission, and arriving by train or bicycle takes 20% off the walk-up price. A reseller earns its keep mainly on day trips from London, where coach, guide and often the White Cliffs come in one price, or if you have no car and want the transfer taken care of. Check every listing for whether admission is genuinely included – and note that the Operation Dynamo section has been closed for maintenance, which few resellers mention.

Opening hours and best time
As published by English Heritage on 20 September 2026: 21 September to 18 October 2026 daily 10:00–17:00. 19 to 25 October daily 10:00–17:00, except Sunday 25 October, which ends at 16:00. 26 October to 1 November daily 10:00–16:00. From 2 November to 20 December 2026 the castle opens on Saturdays and Sundays only, 10:00–16:00, and is shut Monday to Friday. From 21 to 27 December only Sunday 27 December, 10:00–16:00. 28 December 2026 to 3 January 2027 daily 10:00–16:00. 4 January to 14 February 2027 Saturdays and Sundays only, 10:00–16:00; 15 to 21 February (half term) daily 10:00–16:00; from 22 February 2027 Wednesday to Sunday, 10:00–16:00. Last entry is an hour before closing throughout. If you want the castle and the tunnels in one visit you need the early hours – on a 10:00-to-16:00 day it is tight.
When it is quietest
A weekday outside the English school holidays, and ideally at 10:00 when the gates open. The tunnel tours take 30 people at a time and start in quick succession, so arriving early means walking in rather than queuing, and leaves the afternoon for the Great Tower, the Roman lighthouse and the Spur. English Heritage suggests asking staff on arrival when the best moment for the tunnels is that day. From November to mid-February the castle is shut on most weekdays and open only Saturday and Sunday, 10:00–16:00 – too little time for the whole site, but that is also when off-peak pricing makes it cheapest.
Who it suits
With children
The castle as a whole is very good with children: a siege-themed playground, the Great Tower with its holographic figures, and a lot of grass. There is no minimum age for the tunnels, but the tours are dark, loud and deliberately oppressive – often too much for small children. The Dumpy special tour, when it ran, was 18 and over.
Minimum age
None for admission or for the tunnel tours included in it. Age 18 applied only to the Dumpy special tour, which is not currently running.
Wheelchair
The wartime tunnels are not accessible by wheelchair or mobility scooter; English Heritage states that plainly for the Underground Hospital. The Spur tunnels are reached only by a narrow spiral stair – 18 steps down, 26 up, with a handrail. Step-free are the Spur casemates with the siege exhibition, the Georgian barracks display and the Spur viewpoint; a virtual tour of the tunnels runs in the casemates. The only lift on site is inside the Secret Tunnels, and there is none in the medieval part of the castle. The grounds cover 80 acres with some very steep paths, cobbles and gravel; a shuttle bus runs across the site, and wheelchairs and powered scooters can be borrowed if you email ahead.
Pushchair
Pushchairs are fine in the grounds. They will not go into the guided tunnels because of the stairs and gradients, and the spiral stair blocks them in the Spur tunnels.
Dogs
Dogs on short leads in the grounds only, not in the buildings and not in the tunnels. Assistance dogs everywhere. Water bowls stand at the NAAFI restaurant, the ticket office, the tunnel shop and the Great Tower café, and the NAAFI has a dog-friendly area.
Claustrophobia
The wartime tunnels are tight, dark and offer no way past the group. The Dumpy special tour was expressly not recommended for anyone afraid of confined spaces or with chronic asthma or serious respiratory problems. If confined spaces are a problem, stay with the Great Tower and the Spur viewpoint walk.
What to wear
Solid closed shoes with grip: the tunnels have uneven floors, steps and very steep ramps – at the start and the exit of the wartime tunnels the handrail runs only part of the way – and the grass banks turn slippery when wet. On top of the cliff the wind comes straight off the Channel, so bring a windproof layer even in summer.
Photography
Photography is free in the castle grounds; drones are banned and commercial shoots need permission. Visitor accounts agree that photography is not allowed inside the tunnels, though we found no rule page of English Heritage's own saying so (see “unsicher”).
Getting there
By public transport
From London St Pancras International the Southeastern Highspeed runs direct to Dover Priory – fastest 1 hour 3 minutes, typically about 1 hour 7 minutes, with roughly 42 direct trains a day. London Charing Cross also has direct trains, about 20 a day, but they take around 1 hour 52 minutes; from London Victoria it is slower again and usually cheaper. From Dover Priory it is about a mile uphill on foot, or bus 81. Other Stagecoach East Kent routes: 15, 15X, 80, 80A, 81 and 93, with the 15 coming from Canterbury. Keep the ticket – it is worth 20% off at the window.
By car
Free on-site parking for 200 cars, open from castle opening, visitors only. On busy days and event days the overflow is Broadlees (CT16 1HW), five minutes' walk away. There is a free Blue Badge car park by the Great Tower. Sat-nav postcode: CT16 1HU. When the ferry port is jammed, English Heritage suggests approaching by M2/A2 or by A299/A256. Left-hand drive visitors should note the castle road is steep and narrow near the top.
From the nearest city
The castle sits high above the town and the ferry port; from the ferry terminal and the cruise terminal in the Western Docks it is only a few minutes by car, but steeply uphill. London is about 130 km away. Arriving by ferry from Calais or Dunkirk, the castle makes a good first stop in England and is signposted – but there is no left luggage at Dover Castle, so suitcases stay in the car. Flying in, the usual gateways are Heathrow and Gatwick; from either the practical route is into central London and out again from St Pancras, rather than driving across the M25.
Tips for your visit
- If you come by train, bus or bicycle, buy at the window, not online. English Heritage gives 20% off the walk-up price on production of a travel ticket or a bike or helmet, and that beats the 15% online discount: 20% off the standard £31.80 is £25.44 (about $33.95) against £27.03 (about $36.07) online. The discount does not apply to pre-booked tickets, so decide before you click. It runs to 31 March 2027.
- Visiting more than one English Heritage site? The Overseas Visitors Pass, for guests living outside the UK, costs £58 (about $77.40) for one adult and £102 (about $136.11) for two for nine days in 2026/27, and covers over 100 places – Stonehenge, Tintagel, Whitby, Dover. Two Dover tickets alone are about £54. The 16-day versions are £69 and £113, and a family pass is £116 for nine days.
- Check the Dover Castle page the morning you set out. The Operation Dynamo section has been closed for essential maintenance with no reopening date, and the operator's own FAQ page still claims it is open – the notice on the main, prices and things-to-do pages is the one to trust.
- Come early. Each tunnel tour takes 30 people; arriving at 10:00 saves the wait and leaves time for the rest of the castle. English Heritage suggests asking staff on arrival when the best moment for the tunnels is that day.
- Allow three to four hours minimum – that is English Heritage's own floor, and it is a floor. The grounds run to 80 acres with steep paths; the shuttle bus helps but does not spare you the climb into the Great Tower.
- Gift Aid is optional. The +10% you see offered at checkout is a voluntary donation, and the £27.20 adult price quoted on several ticket sites is simply the off-peak fare with that donation already added.
- Travel light. There is no left luggage at Dover Castle, so if you are breaking a ferry or cruise journey, leave the bags in the car.
- Admission buys a great deal more than the tunnels: Henry II's Great Tower, the Roman lighthouse beside the Anglo-Saxon church of St Mary in Castro, the First World War Fire Command Post looking out over the Channel, and a siege-themed playground for children.
- The tea room and the shop at the wartime tunnels sit inside the Napoleonic level itself, and you reach them without a tour. If you skip the guided tunnels, you still see that much.
- Put the camera away underground. Photography is not permitted in the tunnels; everywhere else on site it is fine, and drones are banned throughout.
What the internet gets wrong
The same charity carries a notice on the castle's main page, on the prices and opening times page and on the things-to-do page reading “Unfortunately the Operation Dynamo section of the Secret Wartime Tunnels is currently closed for essential maintenance.” On 20 September 2026 the notice was still up and the FAQ still said the opposite. Follow the notice. The Underground Hospital and the medieval Spur tunnels are open; the Dynamo level is not, and no reopening date has been given.
There is no online booking for the tunnel tours at all. What you book online is a timed entry slot for the castle; the tunnel tours are allocated on site by staff, and English Heritage asks you to check with them when you arrive. The same page puts opening hours at “Daily 10:00–18:00” and adult admission at £22 – in September 2026 the castle closes at 17:00 with last entry at 16:00, and the cheapest adult ticket is £24.65 (about $32.89). A second booking myth circulates alongside it: crazyaboutcastles.com says the advance discount runs “up to 8:45 a.m. on the date of their visit”, when English Heritage closes advance booking at midnight the night before, and the saving is 15%, not the 10% often quoted.
Those are the off-peak prices with the voluntary 10% Gift Aid donation already added, presented as the plain fare. English Heritage's own pricing data gives three seasonal tiers – online £24.65 / £27.03 / £29.32 (about $32.89 / $36.07 / $39.13) and at the gate £29.00 / £31.80 / £34.50 (about $38.70 / $42.43 / $46.04). Every other figure in circulation sits below the 2026 list: £23.60 (crazyaboutcastles.com), £20–£25.50 (handmadekent.co.uk), £22 (castles-palaces.com), £20–£25 (tourismattractions.net) and £20.90–£25.00 (ramblynjazz.com).
Only two of the five levels are wartime work – Annexe, finished as a hospital in 1941/42, and Dumpy, 1942/43. The level the tours run through was cut into the chalk by William Twiss and William Ford in 1797–98 against Napoleon, with the first troops in by 1803, and the Kent Historic Environment Record dates it accordingly. Older still are the Spur tunnels under the northern outworks, dug after the sieges of 1216 and 1217.
English Heritage's facilities page puts the Operation Dynamo tour at 30 people per group “setting off at approximately 15 to 20 minute intervals”, lasting about 50 minutes, and runs the Underground Hospital tour, about 20 minutes, throughout the day from its own separate entrance. Neither is hourly – and at present only the hospital tour is running at all.
Both tunnel tours are included. English Heritage's pricing data carries the line “Admission price includes the Secret Wartime Tunnels tour”, and the facilities page says the Underground Hospital tour “is included in the admission price”. The only part that ever cost extra was the deep Dumpy level, at £10 (about $13.34) on the last special tours in the winter of 2024/25, and those are not in the programme.
And English-language guides turn that into a view across to France: the openings in the cliff face on the Admiralty casemate level look down over Dover harbour, and that is precisely the level closed in 2026. The French coast really is visible on a clear day, but from the open cliff top – the First World War Fire Command Post and the new viewpoint on the northern Spur – across a strait that is only about 33 kilometres wide at its narrowest.
The conversion went ahead. English Heritage and the Kent Historic Environment Record both record that Dumpy was fitted out in the early 1960s as one of twelve Regional Seats of Government, with a filtration plant, dormitories on the Annexe level and a small broadcasting studio, and that it was only stood down in the early 1980s.
History in brief
- After the sieges of 1216 and 1217 in the First Barons' War, when Prince Louis of France forced the north gate but could not hold it, the gate was walled up and replaced by an underground forward defence: a tunnel under the outer wall to St John's Tower and on beneath the outwork, where it divided into three passages.
- In 1797/98 the engineers William Twiss and William Ford drove seven casemates into the chalk – four smaller western ones with an upper storey, three larger eastern ones, plus connecting and access tunnels. Underground barracks were a novelty at the time; because the chalk kept slipping, the rooms were lined in brick by 1810.
- The first troops moved in during 1803. At the height of the Napoleonic Wars more than 2,000 men lived under the castle – and these remain the only underground barracks ever built in Britain.
- From 1818 to 1828 the Coast Blockade used the tunnels against smugglers. After that they stood empty for more than a hundred years.
- In 1939 the empty casemates were recommissioned as the bomb-proof headquarters of the Vice-Admiral, Dover, and as an operations room for coastal and anti-aircraft artillery. From here Vice-Admiral Bertram Ramsay ran Operation Dynamo between 26 May and 4 June 1940: 338,226 men brought home, 224,320 of them British, with 933 ships involved and 236 lost. More than two thirds – 239,465 – were lifted from the harbour mole, 98,761 from the beaches.
- Two new levels followed: Annexe, finished as a small hospital early in 1942, and Dumpy, completed in 1943 as a combined headquarters for all three services with a large telephone exchange. Dumpy played a part in Operation Neptune, the naval side of D-Day, and in Fortitude South, the deception that kept the Germans expecting the main landing near Calais.
- The army left in 1958. In the early 1960s Dover Castle was designated one of twelve Regional Seats of Government, meant to take over administration in a nuclear war. Dumpy was the core, Annexe became dormitories and the western part of Casemate a canteen and mess; the complex was given a filtration plant, communications equipment and a small broadcasting studio. It was stood down in the early 1980s.
- Only then did the tunnels pass to English Heritage and get fitted out for visitors. To this day only the Casemate and Annexe levels are regularly accessible; Bastion counts as lost and the search for a way in continues, while Dumpy and Esplanade are closed.
Frequent questions
Are the Dover Castle tunnels open in 2026?
Partly. The Operation Dynamo section of the Secret Wartime Tunnels has been closed for essential maintenance for some time and was still closed on 20 September 2026. Open are the Underground Hospital, on its own guided tour, and the medieval Spur tunnels, which you walk through without a guide. English Heritage gives no reopening date – and its own FAQ page still claims everything is open, so check the notice on the main castle page before you travel.
How much does Dover Castle cost?
Booked online in advance, adults pay £24.65 to £29.32 depending on the seasonal tier – about $32.89 to $39.13. At the gate it is £29.00 to £34.50. Children aged 5 to 17 pay £12.32 to £14.62 online and under-5s go free. A family ticket for two adults and up to three children is £61.79 to £73.35 online. English Heritage members get in free. Prices as of September 2026.
Are the tunnel tours included in the admission price?
Yes. English Heritage states it in its own ticket data: “Admission price includes the Secret Wartime Tunnels tour”, and the same goes for the Underground Hospital tour. The only thing that has ever cost extra is the special tour into the deep Dumpy level – £10 when it last ran – and that is not currently offered. Any site telling you the tunnels need a separate ticket is wrong.
Do you need to book Dover Castle tickets in advance?
You do not have to, but booking online by midnight the night before saves 15%. The ticket covers a timed entry slot; after that you can stay until closing. One exception is worth knowing: if you arrive by train, bus or bicycle you get 20% off the walk-up price at the window, which beats the online saving – but it does not apply to tickets already booked.
Can you visit the tunnels without a guided tour?
Only the medieval ones. The Spur tunnels under the northern outworks are walk-through, part of the Dover Castle Under Siege exhibition, with no guide and no queue. Both wartime levels are guided-tour-only, capped at 30 people, and English Heritage bans independent guiding there. Since the Dynamo section is closed, the Underground Hospital is the only guided tunnel running in 2026.
How long do you need at Dover Castle?
English Heritage recommends a minimum of three to four hours, and that is tight. The wartime tunnel tour takes about 50 minutes when it runs, the Underground Hospital 20 minutes, and on top of that come the Great Tower, the Roman lighthouse, the siege exhibition with the medieval tunnels and 80 acres of grounds. A full day is realistic.
How do you get to Dover Castle from London?
The Southeastern Highspeed from London St Pancras International reaches Dover Priory in about an hour – 1 hour 3 minutes at best, roughly 42 direct trains a day. London Charing Cross has about 20 direct trains a day taking around 1 hour 52 minutes, and London Victoria is slower again. From Dover Priory it is a mile uphill on foot or bus 81. Keep the ticket: it is worth 20% off at the window.
How many steps are there?
The medieval Spur tunnels have 44: 18 down at the entrance and 26 up at the end, with a handrail. No step count is published for the wartime tunnels, which have steep ramps rather than long staircases, plus a lift; the Underground Hospital exit has steep stairs with the lift as the alternative. The Dumpy special tour warned of 80 steps to climb unaided if the lift failed.
Are the tunnels wheelchair accessible?
No. English Heritage says plainly that the Underground Hospital cannot be done in a wheelchair or mobility scooter, and the Spur tunnels are reached only by a narrow spiral stair. Step-free are the Spur casemates with the siege exhibition, the Georgian barracks display and the Spur viewpoint, and a virtual tour of the tunnels runs in the casemates. A shuttle bus crosses the steep site, and wheelchairs and scooters can be borrowed if you email ahead.
Can you take photos in the tunnels?
Visitor accounts agree that you cannot – the underground pictures in travel write-ups are usually English Heritage's own. Elsewhere on site photography is welcome; drones are banned and commercial shoots need permission. We could not find a rule page of English Heritage's own stating the tunnel ban, so treat it as the practice rather than a published rule.
How deep and how long are the tunnels?
The whole network is about three miles, roughly 4.8 kilometres, across five levels: Annexe, Bastion, Casemate, Dumpy and Esplanade. The level the tours use lies about 15 metres below the cliff top. The deepest, Dumpy, is around 50 metres down and is not part of the ordinary visit; Bastion is recorded as lost, and English Heritage is still looking for the way in.
Can you see France from Dover Castle?
From the open cliff top, on a clear day, yes – the strait is only about 33 kilometres wide at its narrowest, and the First World War Fire Command Post and the new viewpoint on the northern Spur look straight across it. Not from inside the tunnels: the openings in the cliff face on the Admiralty casemate level look down over Dover harbour, and that level is the one closed for maintenance in 2026.
Is Dover Castle worth it with children?
Yes, as long as the tunnels are not the whole point. There is a large siege-themed playground, the Great Tower with holographic figures and objects children may handle, high chairs and lunch boxes in the cafés, and a great deal of grass with a Channel view. The tunnel tours are dark and loudly staged – at 20 minutes the Underground Hospital is the gentler option.
Can you tour the Cold War bunker under Dover Castle?
Not at the moment. English Heritage last ran the Dumpy special tour in the winter of 2024/25, at a £10 surcharge, age 18 and over, with tickets sold on site on the day. The event page for it no longer exists and the Dover Castle events calendar shows no dates. Whether it comes back is open, so do not plan a trip around it.
How many soldiers were rescued in Operation Dynamo?
English Heritage gives 338,226 men, 224,320 of them British, lifted between 26 May and 4 June 1940. 933 ships took part and 236 were lost. Contrary to the popular picture, most did not leave in little ships from the sand: 239,465 boarded from the harbour mole at Dunkirk and 98,761 from the beaches.
Is the English Heritage Overseas Visitors Pass worth it?
For a trip taking in several historic sites, usually yes. For visitors living outside the UK the 2026/27 pass costs £58 for one adult and £102 for two for nine days, £116 for a family, and covers over 100 places including Dover Castle, Stonehenge and Tintagel. Two adult tickets at Dover alone come to about £54. Ordinary annual membership starts at £44 and brings up to six accompanied children in free per adult member.
