Caves Under Budapest: Pál-völgyi, Szemlő-hegyi and the Crawl-Through Caving Tour
On this page
Pál-völgyi Cave and the caves joined to it make up Hungary’s longest cave system, about 32 kilometers of known passages under a villa district in Budapest’s District II. Two show caves there, Pál-völgyi and Szemlő-hegyi, are lit and paved, so you walk through in ordinary clothes plus a sweater: they stay at 11 to 12°C all year.
If you are fit and doing one cave, pick Pál-völgyi, with its 400-plus steps and 7 meter ladder; small children, prams and wheelchairs go to Szemlő-hegyi. For real crawling in overalls, book the Mátyás-hegy adventure tour ahead. Plan around the calendar: Pál-völgyi closes on Mondays and Szemlő-hegyi on Tuesdays.

Why a capital city has caves at all
The Buda hills are limestone, and the same hot water that feeds the city’s thermal baths once rose through that rock and dissolved it from below. The result is a cave system under a residential district: villas on top, kilometers of passages underneath. Pál-völgyi alone, joined to the Mátyás-hegy and other caves, now runs to about 32 kilometers of known passages, the longest in Hungary.
Two short stretches are lit, paved and open to anyone with a ticket. Everything else is either closed to visitors or reachable only in overalls with a guide.
Pál-völgyi Cave: the one with the ladder
What it is. A 500 meter developed route through the most dramatic accessible part of the system, discovered in a quarry in 1904 and open to visitors, with breaks, since 1919. The tour lasts about an hour. Expect tall, narrow fissure passages, big height differences and round hollows dissolved by thermal water, plus dripstones, calcite crystals and fossil shell imprints in the rock.
Why it is worth it. It feels like a proper cave rather than a cellar with lighting. The trade-off is physical: more than 400 steps and a 7 meter ladder with handrails, the so-called hen ladder. If stairs are your weak point, this is the one to skip.
The rules. No entry under age 5 or under 115 cm, no dogs, maximum 35 people per tour. If a tour is full, you get a ticket for the next one.
Language. For visitors who do not speak Hungarian, the national park offers a free audio guide app in English, German, French, Spanish, Russian, Ukrainian, Italian and Polish; download it before you go, because you will want it underground. Private groups can arrange an English-speaking guide in advance, for a 16,000 HUF fee on top of the tickets. The bat-watch tour is in Hungarian only.
The facts. Szépvölgyi út 162, 1025 Budapest. Open every day except Monday; tours leave at a quarter past every hour, first 10:15, last 16:15. Buy your ticket at the visitor center across the road at least 10 minutes before the tour; the center also holds a small interactive exhibition on caves and bats. Closed 24, 25, 26 and 31 December and 1 January. Cash, card and SZÉP card are accepted.
Szemlő-hegyi Cave: the gentle one
What it is. A shorter, flatter cave less than a kilometer away as the crow flies, found during a building job in a villa district and now sitting under a small park. The basic tour takes about 40 minutes. Its walls are covered in knobbly mineral crusts, and some formations have names, such as the Sunken Ship and the Polar Bear, which star in the children’s story told in the visitor center.
Why it is worth it. It is the cave for families and for anyone who cannot do 400 steps: the route is accessible with a pram or a wheelchair. There is a stair lift at the entrance and the cave route uses 15 degree ramps, so the park advises bringing a companion if you use a wheelchair. Above ground there is a playground, a geology trail and an exhibition where children can try rope technique and squeeze through a replica of the Needle’s Eye. The weakness: after Pál-völgyi it can feel short, so if you only do one cave and you are fit, do the other one.
The facts. Pusztaszeri út 35, 1025 Budapest. Open every day except Tuesday; tours leave on the hour, first 10:00, last 16:00. Closed 24, 25, 26 and 31 December and 1 January. No dogs. The same free audio guide app covers this cave.

Prices are in HUF, which is what you pay at the ticket desk. Converted at 1 USD = 323 HUF, the ECB rate on 16 October 2026. Rates move, so treat the converted figures as indicative.
Concessions cover children, students, pensioners, teachers, and up to two adults accompanying two or more children. Discounts do not stack. The combined ticket is the obvious buy if you want both: it saves 1,900 HUF and you do not have to use the second half on the same day.

The Mátyás-hegy adventure tour: overalls on
What it is. A guided trip into the undeveloped Mátyás-hegy section of the Pál-völgyi system, run from the same Szépvölgyi út address. There is no path and no lighting. Several times you move on all fours or slide through on your belly. No experience is needed, only a sporty attitude, and the overalls, helmet and headlamp are provided.
Why it is worth it. You see the cave system in its natural state, inside the city limits and reached by city bus. The trade-off is obvious and real: it is tight, it is dark, and it is not for anyone who panics in small spaces.
Who can go. From school age, shown with a student card. The extreme tour is 14 and over and runs in Hungarian only.
| Tour | Length | Full price | Concession |
|---|---|---|---|
| Adventure Caving Tour in English | 2.5 to 3 hours | 24,000 HUF (about $74) | discounted price 16,000 HUF (about $50) |
| Caving team building in English | see the booking page | 24,000 HUF (about $74) | |
| Basic adventure tour, in Hungarian only | see the booking page | 14,700 HUF (about $46) | 9,000 HUF (about $28), students 6 to 14 |
| Extreme tour, in Hungarian only, age 14+ | 3 hours | 19,900 HUF (about $62) | |
| Caving team building in Hungarian | 3.5 hours | 19,900 HUF (about $62) |
Prices are in HUF, as the national park and the operator list them. Converted at 1 USD = 323 HUF, the ECB rate on 16 October 2026. Rates move, so treat the converted figures as indicative.
Tours run all year, by advance booking only, through barlangaszat.hu, the operator named by the national park. The 14,700 HUF tour is for people who can follow the guide’s instructions in Hungarian; everyone else books the English tour. Check the start times there before you plan the rest of the day around it.

Which one to pick
- Small children, a pram, bad knees or a wheelchair: Szemlő-hegyi. The guide to Budapest with kids has the rest of a family day around it.
- One cave, reasonably fit adults: Pál-völgyi. It is the more impressive cave, and the ladder is part of the fun.
- Both in one morning: the two caves are under a kilometer apart as the crow flies. Take the 10:00 Szemlő-hegyi tour, which ends around 10:40, and aim for the 12:15 Pál-völgyi tour without rushing. Buy the combined ticket at the first cave. Bus 29 runs from the Szemlő-hegyi-barlang stop down to Kolosy tér, where you change to bus 65.
- You want a story you will still tell in ten years: the Mátyás-hegy adventure tour, booked ahead.
- Monday: Szemlő-hegyi only. Tuesday: Pál-völgyi only.
Two seasonal notes. In a heat wave both caves are the coolest places in the city, which is why they get their own section in the Budapest heat wave survival guide. In rain they are equally good, since the weather stops at the entrance; the rainy day guide has the indoor plans for the rest of the day.
Christmas and New Year 2026/27, day by day. Both caves are closed on Thursday 24, Friday 25 and Saturday 26 December. On Sunday 27 December both are open, on Monday 28 December only Szemlő-hegyi, on Tuesday 29 December only Pál-völgyi, and on Wednesday 30 December both again. They close again on Thursday 31 December and Friday 1 January, and the normal week resumes on Saturday 2 January. The national park lists no separate winter timetable, so on every open day the tours leave at the usual times.
Man-made caves and bunkers
The caves under Castle Hill are a different thing: natural cavities that people widened, walled and reused for centuries. If you are already up there, they are the easier add-on, and further out, Csepel has its wartime bunkers.
- Hospital in the Rock is a wartime hospital and Cold War nuclear bunker built into the caves under Buda Castle, visited on a guided tour. It is history, not geology, and it is the more moving of the two.
- The Buda Castle Labyrinth is a self-guided walk through cellars and passages under the Castle District, short, theatrical and suitable for an hour between other sights.
- The Csepel bunker tour goes further from the center, into World War II air raid shelters under the Csepel Works, for when the underground history bug has properly bitten.
None of them is a cave in the sense Pál-völgyi is. If you want limestone shaped by hot water rather than by masons, you have to go to District II.
Good to know
Which cave in Budapest is the best to visit?
Pál-völgyi, if you can manage stairs. It is the longest cave system in Hungary, and its one-hour tour climbs more than 400 steps and a 7 meter ladder through tall, narrow fissures. Szemlő-hegyi is the gentler choice: about 40 minutes, accessible with a pram or a wheelchair, and full of knobbly mineral formations. If you want to crawl rather than walk, the Mátyás-hegy adventure tour is a different category altogether.
Are the Budapest caves open on Mondays?
Szemlő-hegyi is, Pál-völgyi is not. Pál-völgyi closes on Mondays (it does open on Monday public holidays, apart from the Christmas and New Year days), and Szemlő-hegyi closes on Tuesdays instead. From Wednesday to Sunday both are open. Both close on 24, 25, 26 and 31 December and on 1 January.
How much does the caving tour in Budapest cost?
The English-language Adventure Caving Tour in the Mátyás-hegy section of the Pál-völgyi cave system takes 2.5 to 3 hours and costs 24,000 HUF per person, or 16,000 HUF at the discounted price, with overalls, helmet and headlamp provided. The 14,700 HUF tour (9,000 HUF for students aged 6 to 14) is in Hungarian only, for people who can follow the Hungarian guide's instructions, and the 19,900 HUF extreme tour also runs only in Hungarian. Caving team building in English is 24,000 HUF per person. Tours run all year by advance booking only.
Can children visit the caves in Budapest?
Yes. Szemlő-hegyi takes any age, and under-3s need only a 200 HUF registration ticket. Pál-völgyi does not admit children under 5 or under 115 cm, because of its steps and ladder. The Mátyás-hegy adventure tour starts at school age, proven with a student card, and the extreme tour, run in Hungarian only, at 14.
What should I wear in the Budapest caves?
Normal street clothes and comfortable walking shoes are fine in both show caves, plus a warm layer: Pál-völgyi is 11°C and Szemlő-hegyi 12°C all year. On the adventure tour you get overalls, a helmet and a headlamp.
How do you get to Pál-völgyi Cave?
Take bus 65 from Kolosy tér in Óbuda to the Pál-völgyi cseppkőbarlang stop. The ticket office is in the visitor center across the road from the cave, at Szépvölgyi út 162, and tickets must be bought at least 10 minutes before the tour. For Szemlő-hegyi, bus 29 from Szentlélek tér or Árpád híd stops above the cave, and the entrance is 100 meters downhill at Pusztaszeri út 35.
Are the Budapest caves open at Christmas and New Year?
Not on the holidays themselves: Pál-völgyi and Szemlő-hegyi are both closed on 24, 25, 26 and 31 December 2026 and on 1 January 2027. In between, the usual closing days apply: on Sunday 27 December both are open, on Monday 28 December only Szemlő-hegyi, on Tuesday 29 December only Pál-völgyi, and on Wednesday 30 December both, with the normal hourly tours.
