Mallorca has five show caves, and five separate companies run them – one ticket never covers two. The Coves del Drac at Porto Cristo are what most people fly in for: a 1,200-metre route 25 metres down to Lake Martel, where a string quartet has played from lit rowing boats since 1935, and where entry is by fixed time slot rather than whenever you turn up. The Coves dels Hams are a kilometre away and put on something quite different; Coves d'Artà sit high above the sea near Canyamel and give you the island's only proper guided tour in English; Campanet in the north is the quiet one; and Gènova, ten minutes from the middle of Palma, is the one that fits around a cruise call or a city break. Which of the five suits you is decided less by the stalactites than by where you are staying, how you feel about crowds, and how many steps the people you are with can manage.

The five show caves of Mallorca, compared
Coves del Drac (Cuevas del Drach, the Dragon Caves)
The famous one, at Porto Cristo: a 1,200 m route 25 metres down, ending at Lake Martel with a live classical concert played from lit rowing boats. Also the crowded one.
Lake Martel, 117 by 30 m and 4 to 12 m deep, which the operator calls one of the biggest underground lakes in the world. Since 1935 a quartet – cello, harpsichord and two violins – has played four classical pieces from the boats, followed by a lighting sequence called Dawn on the Lake. Afterwards you cross the lake by boat or over the bridge, at no extra charge either way. No guide, no commentary; photography is banned for the ten minutes of the concert.
Adults €18.50 (about $21.20) online, €19.50 (about $22.35) at the desk; ages 3–12 €11.50 / €12.50; under 3s free (09/2026)
Coves dels Hams (Cuevas dels Hams)
Drach's neighbour, 1 km west of Porto Cristo, and a different proposition: three parts – a round collapsed chamber turned into a garden, a Blue Cave with a film, and the classic cave with twelve galleries and a music show on the lake called Mar de Venecia.
The name comes from hook-shaped, twisted formations: hams is Catalan for fish hooks. Found in 1905 by Pedro Caldentey and opened to visitors in 1910 – according to Spanish Wikipedia the first show cave in Spain, and electrically lit from early on. The Blue Cave has shown a documentary on the island's history since 2015. A steady 20 °C.
Adults €18.50 (about $21.20) online, €19.50 (about $22.35) at the desk; ages 3–12 €12.50 / €13.50; under 3s free, maximum two per adult; combined with Dinosaurland €26 (about $29.80) (09/2026)
Coves d'Artà (Cuevas de Artà)
A cathedral of a cave high above the sea near Canyamel, entered through a monumental rock portal, with ceilings from 15 to 45 m and the formation known as the Queen of Columns.
The one cave on the island with a real guided tour, given in Spanish, English, French and German. The route runs through the vestibule, the Hall of Columns, the Queen of Columns, Hell with its light-and-sound sequence, Purgatory, the Theatre, the Hall of Flags and Glory: over 700 m of path, about 6,000 m², 17–22 °C and very humid. The exit opens straight onto the Mediterranean. In 1229 the last Moorish fighters are said to have hidden here from the army of Jaume I, and the visitors' book begun in 1869 carries the names of Jules Verne and Victor Hugo.
Adults €17 (about $19.48); ages 7–12 €10 (about $11.46); under 7s free; Balearic residents €13 / €8 (09/2026)
Coves de Campanet
The quietest show cave on the island, on the southern slope of the Puig de Sant Miquel in the north, known for unusually fine, thin formations.
Found in June 1945 when Bartomeu Palou followed a draught coming out of a hole in the rock, and opened on 10 November 1948. About 3,200 m² of chambers some 50 m below the surface, with names like Sala Romántica, Sala del Lago and Castillo Encantado. Building work turned up fossils of Myotragus balearicus, the extinct Balearic goat-antelope. The terrace looks out over the valley of Sant Miquel.
Adults €17 (about $19.48); ages 4–12 €9 (about $10.31); audio guide optional (09/2026)
Cuevas de Génova (Coves de Gènova)
A small cave in Palma's Gènova district, stumbled on during digging work in 1906, reaching 36 m down.
The only show cave within reach of the city: about 10 minutes from the centre, a bus stop 50 m from the door, free parking. You go round on your own with a multilingual audio-guide app on your own phone. Coloured lighting picks out formations that look like cauliflower and popcorn; there are some high steps and tight corners.
Adults, ages 12 and over, €12 (about $13.75); children up to 12 €7 (about $8.02); audio-guide app included (09/2026)
Tickets and prices
Drach sells online about 30 days ahead, each ticket carrying a fixed entry time, and is €1 cheaper than the desk. The ticket on your phone is all you need: you walk straight to the cave entrance, 200 m from the free car park, and the operator asks you to be there 15 minutes early. Hams also sells online with a chosen time. Artà, Campanet and Gènova are normally bought on the spot, though online booking exists for all three.

When everything is sold out
Only Drach genuinely sells out. In high season the middle of the day goes first, because that is when the coach tours are scheduled. Miss the time on your ticket and you lose it – Drach does not refund and does not rebook. If a slot you want has gone, the 10:00 or the 17:00 usually has not.
Tickets and day trips to the Mallorca caves
Booking direct is cheaper than anything here: Drach is €18.50 (about $21.20) on the operator's own site, Hams the same, Artà and Campanet €17 (about $19.48). What a reseller sells is the journey, and on this island that is worth something – Artà and Campanet are hard to reach without a car, and a day trip from Palma or Alcúdia saves the hire car and the parking. Read the description before you book. Check which cave the offer actually enters, because "Mallorca caves" covers five separate businesses. Check whether admission is included or whether you are paying for a coach seat and buying the ticket yourself at the door. And check the time: Drach runs on fixed slots, so an excursion that arrives at 13:00 has nowhere to put you.

Opening hours and best time
Every cave keeps its own hours – details under each one below. Drach admits visitors at fixed times only: 16 March to 31 October at 10:00, 11:00, 12:00, 14:00, 15:00, 16:00 and 17:00; 1 November to 15 March at 10:30, 12:00, 14:00 and 15:30. Note the gap over lunch and that there is nothing after 17:00. Closed 25 December and 1 January. Hams is generally open 10:00 to 17:00, with a time slot chosen when you buy; a few winter dates are blocked in the operator's calendar. Artà: May to October 10:00–18:00, November to April 10:00–17:00, a group setting off roughly every 30 minutes, closed 25 December and 1 January. Campanet: daily from 10:00, closed 25 December and 1 January. Gènova: 9:30–17:30 daily according to the ticket portal.
When it is quietest
At Drach, take the first admission at 10:00 or the last at 17:00; between 11:00 and 15:00 the coaches arrive. Rainy days are the busiest days of the year, because the whole island drives to the caves at once – the caves themselves run normally in rain. The low season from November to mid-March has only four admissions a day, but far smaller groups. Artà, Campanet and Gènova are relaxed at any hour; at Artà the late afternoon is worth aiming for, because you walk out of the cave mouth into the light over the bay.
Who it suits
With children
Drach: the lights, the boats and the concert land well with children, but an hour in a dense crowd and ten minutes of enforced silence in the dark are a lot for a toddler. Hams: usually the easier of the two in Porto Cristo – a garden with birds inside a collapsed chamber, films, and the Dinosaurland combined ticket. Gènova: short at 30 minutes and close to Palma, good for half a morning. Artà and Campanet: fine from the age at which a child handles stairs confidently.
Minimum age
None. Under-3s go free at Drach and Hams, under-7s at Artà, under-4s at Campanet. Drach's rules require anyone under twelve to be accompanied by an adult.
Wheelchair
None of the five is wheelchair-accessible inside. Drach's own rules page states that prams and wheelchairs cannot be used in the caves because of the steps; the grounds, bar and shop are accessible. Hams: no wheelchair access. Gènova: the ticket portal says it is unsuitable for visitors with reduced mobility. Treat all five as a stairs-only day.
Pushchair
Not possible at Drach or Hams, and in practice not at the other three either. Bring a carrier rather than a pushchair.
Dogs
Drach: not allowed, guide dogs excepted. Gènova: no pets. Nothing documented for the other three.
Claustrophobia
The chambers are mostly large and high – Artà's ceilings run from 15 to 45 m. What feels tight is the crowd rather than the rock: at Drach several hundred people move through together on one admission. Gènova has some high steps and a few narrow corners.
What to wear
At 17–22 °C all year the caves are mild – cooler than outside in August, warmer in January. You will not need a coat. You will need flat shoes with grip: the paths are wet and there are a great many steps, 217 up and 148 down at Hams alone. Humidity is high, and highest at Artà.
Photography
Drach: photographs and home-format video are allowed without flash, but taking pictures or filming during the concert is forbidden and the staff enforce it. Tripods, selfie sticks and similar are banned, and professional equipment needs permission in advance. Food, drink, smoking and vaping are all prohibited inside. Hams: no flash, no tripods, no selfie sticks.
Getting there
By public transport
There is no train to any of the five. For Porto Cristo, the TIB intercity bus 401 runs from Palma and, according to the operator, stops at the door of the Cuevas dels Hams, about 90 minutes end to end; from the Hams stop the Drach entrance is a walk of 1–2 km along the road. Gènova is the easy one: a city bus from central Palma, the stop 50 m from the entrance, roughly every 12 minutes per the operator. Artà and Campanet are awkward without a car.
By car
Drach: free car park, 200 m to the entrance, picnic tables and wi-fi. Hams: free car park on the Ma-4020 at km 11. Campanet: Palma–Sa Pobla motorway, the Ma-13, exit 37. Gènova: free car park, about 10 minutes from the centre of Palma. A hire car picked up at the airport is the normal way to do this, and it is what makes combining two caves in a day possible at all.
From the nearest city
From Palma airport (PMI) to Porto Cristo is about 62 km by road, roughly 50 minutes to an hour by car; from the city itself allow an hour. From Alcúdia and the northern resorts, Porto Cristo is about 53 km and 50 minutes, while the Coves de Campanet are only about 18 km and 17 minutes away – if you are based in the north, Campanet is the sensible cave and Drach is a day out. Artà lies further round the north-east coast at Canyamel in the municipality of Capdepera, best from Cala Rajada, Cala Millor or Canyamel. Gènova is a district of western Palma. Drach and Hams are 1–2 km from each other.
Tips for your visit
- Book Drach online. It is €1 cheaper, it guarantees your admission, and it saves the queue at the desk – but book only once the date is certain, because there is no cancellation and no refund if you arrive after your time.
- Once inside Drach, stay near the front of the group. Whoever reaches the lake first sits at the front for the concert and does not spend long waiting for a boat afterwards. The crossing is optional; the bridge is quicker.
- Photographs are fine in the caves without flash, and forbidden for the ten minutes of the concert. Leave the tripod and the selfie stick in the car – both are banned at Drach and at Hams.
- Avoid Drach on a wet day, or take the 10:00 slot. Rain sends the whole island underground. Campanet and Artà stay calm even then.
- Doing Drach and Hams on the same day is possible, 1–2 km apart, but two shows back to back is a lot. One of them plus the harbour and beach at Porto Cristo is the better afternoon.
- Wear flat shoes with grip. Every one of the five has damp paths and a lot of steps – Hams alone has 217 going up.
- With a baby, bring a carrier, not a pushchair, and remember that Drach asks for complete silence in the dark during the concert.
- If you want the cave explained in English, go to Artà: it is the only one of the five with a live guide who works in English, and groups leave about every half hour.
- Coach packages with a transfer and a pearl-factory stop cost several times the admission. A hire car, or the TIB 401 bus to Porto Cristo, gets you there cheaper and at the time you chose.
What the internet gets wrong
Three errors in one entry. The operator's own English page reads "One of the biggest underground lakes in the world, 117 metres long, 30 metres wide and between 4 and 12 metres deep" – one of, not the, and 117 metres, not 170. Europe's largest is the Lac Souterrain de Saint-Léonard in the Swiss Valais, 300 m long and about 6,000 m² of water against Lake Martel's roughly 3,500 m². And the 2026 prices are €18.50 online and €19.50 at the desk for ages 13 and over, €11.50 and €12.50 for ages 3 to 12; the desk surcharge is €1, not 50 cents.
The operator gives 117 by 30 m and 4 to 12 m deep, so the lake here has grown by 60 metres in length and 10 in width and lost its deep end. The world's largest underground lake is not in Mallorca at all: Guinness lists Dragon's Breath Cave in Namibia, whose lake covers almost 2 hectares – Lake Martel covers about a third of one. The 2026 adult price is €18.50 online or €19.50 at the desk, and ages 3 to 12 pay €11.50 or €12.50.
There is no guided tour at Drach in any language. The operator's FAQ is explicit that the visit is not guided – you walk a marked 1,200 m route with your admission group, and geology is barely mentioned. The visit runs about 60 minutes including the ten-minute concert, not 90. And Drach's own rules page states that prams and wheelchairs cannot be used in the caves because of the steps, which is the opposite of all fitness levels. The cave that does give you a live guide in English is Artà, on the other side of the island.
Prices at Drach have moved twice since those figures were written and now stand at €18.50 online, €19.50 at the desk, €11.50 or €12.50 for ages 3 to 12. The free age band is under 3, not under 2, so a two-year-old now needs a ticket. And the cave is closed on 25 December and on 1 January only – not for the week in between, which is a busy one.
True in November, expensive advice in August. Drach admits visitors at seven fixed times a day in summer and four in winter, with nothing between 12:00 and 14:00 and nothing after 17:00, and the middle of the day is when the coach tours are booked. Buy at the desk on an August morning and the realistic outcome is the 16:00 or 17:00 slot, or tomorrow. The grain of truth is that a Drach ticket is unforgiving: fixed time, no cancellation, no refund, no entry if you are late – so book the day, not the holiday.
The crossing is not rationed, not extra and not a tour feature. The operator's own page says that once the concert ends you can cross Lake Martel by boat or on foot over the bridge at no additional cost, and there is only one kind of admission ticket, which already contains the walk, the concert and the boat. What the €50 buys is the coach and the pearl-factory stop.
Two different companies, 1–2 km apart, and a ticket for one is worthless at the other. Only Drach has Lake Martel and the live quartet that has played from rowing boats since 1935. Hams has its own lake, the Mar de Venecia, with a light-and-music show, plus a garden inside a collapsed chamber and a film in the Blue Cave; the route is about 500 m with 217 steps up and 148 down. Both charge €18.50 online. Hams is not a budget copy of Drach – it opened to visitors in 1910, five years after it was found, and Spanish Wikipedia calls it the first show cave in Spain.
The chronology rules it out. Journey to the Centre of the Earth was published in 1864, and the Artà visitors' book that carries Verne's name only begins in 1869 – the novel came first, so the cave cannot have inspired it, and even the sites that repeat the story concede that it has never been confirmed Verne set foot on Mallorca. The operator's own visit page gives the Queen of Columns as 17 m, not the 22 m that German Wikipedia and the listings pass around. Admission in 2026 is €17 for adults, €10 for ages 7 to 12, free under 7.

Frequent questions
How much are tickets to the Caves of Drach in 2026?
Adults from 13 years pay €18.50 (about $21.20) online and €19.50 (about $22.35) at the ticket desk; children aged 3 to 12 pay €11.50 or €12.50, and under-3s go free. That single price already covers the walk, the concert on Lake Martel and the boat crossing. Prices are as of September 2026.
Do you need to book Drach Caves tickets in advance?
It is not compulsory, but in summer it is close to it. Entry is by fixed time slot and the midday slots are often gone before the day. Online you can book a time about 30 days ahead and save €1. The catch: there is no cancellation, and if you arrive after your time the ticket is void.
How long does a visit to the Caves of Drach take?
About an hour underground, including the roughly ten-minute concert, plus the 15 minutes the operator asks you to be there beforehand and any wait for a boat afterwards. From Palma, with the drive each way, treat it as half a day.
Is the boat ride on Lake Martel included in the ticket?
Yes, and it is optional. When the concert ends you either queue briefly for one of the small boats or walk over the bridge; both are covered by the ordinary ticket and neither costs anything extra. There is only one kind of admission ticket at Drach.
Can you take photos in the Caves of Drach?
Yes, without flash, and no during the concert – photographing or filming those ten minutes is forbidden and the staff enforce it. Tripods and selfie sticks are banned throughout, as they are at Hams, and professional gear needs permission in advance. Food, drink, smoking and vaping are not allowed inside either.
Can you swim in the underground lake?
No. Lake Martel is there to be crossed by boat or walked past on the bridge, and nothing in any of the five caves is a swimming attraction. Drach's rules require you to stay on the marked path, and leaving it is explicitly forbidden. The sea is a short drive away; the cave is not a cenote.
Is Lake Martel the largest underground lake in the world?
No. The operator only ever claims it is one of the biggest, and at 117 by 30 metres it is about a third of a hectare. The Guinness record holder is the lake in Dragon's Breath Cave in Namibia at almost 2 hectares, and Europe's largest is the Lac Souterrain de Saint-Léonard in Switzerland, 300 metres long. Lake Martel is still the most beautiful one you can sit beside and listen to a quartet.
Drach or Hams – which cave should I choose in Porto Cristo?
Drach is bigger, 1,200 m of route, with the lake and the live concert on boats, but also the biggest groups and no commentary at all. Hams is smaller and more produced – the garden, the films, the Mar de Venecia music show – usually less crowded, and its Dinosaurland combined ticket suits families. Both charge €18.50 online, so the choice is about the experience, not the money.
Which cave is closest to Palma?
The Cuevas de Génova, in the Palma district of the same name: about 10 minutes from the centre with a bus stop 50 m from the entrance. The visit takes about 30 minutes and costs €12 (about $13.75) including the audio-guide app. Every other show cave on the island is 45 to 75 minutes away by car.
How do you get from Palma airport to the caves without a car?
There is no direct link. Porto Cristo is about 62 km from the airport, roughly 50 minutes to an hour by car, and public transport means going into Palma first and taking the TIB 401 intercity bus, which stops at the Cuevas dels Hams after about 90 minutes. Gènova is reachable by Palma city bus. For Artà and Campanet you realistically need a hire car or a coach excursion.
How many steps are there, and can you visit with a wheelchair or a pushchair?
No. All five are stairs-only inside: Drach's rules page says prams and wheelchairs cannot be used because of the steps, Hams counts 217 steps up and 148 down, and the Gènova ticket portal calls the cave unsuitable for visitors with reduced mobility. At Drach the grounds, the bar and the shop are accessible even if the cave is not. With a baby, bring a carrier.
How cold is it inside – do you need a jacket?
No. All five sit between about 17 and 22 °C all year, cooler than the August street and warmer than a January one, with high humidity, worst at Artà. What matters far more than a jacket is flat shoes with grip for wet stone and a great many steps.
Which Mallorca cave is the least crowded?
Campanet in the north and Artà in the north-east. Neither takes coach parties on the hour: Artà sends off a manageable group roughly every 30 minutes, and Campanet you walk yourself with an audio guide. Both are the right answer on a rainy day, when the whole island heads for Drach.
Are the caves worth visiting if it rains?
Yes, and that is exactly the problem – rainy days are the busiest days of the year at Drach because everyone has the same idea. The caves themselves run normally in rain. If the forecast is wet, take the 10:00 admission or go to Campanet or Artà instead.
