Duna-Ipoly National Park · Under the Castle District

The caves under Castle Hill

A guided walk through the limestone caverns and medieval cellars under the Castle District, led by guides from the Duna-Ipoly National Park. Pick it because it is the official way into the cave system, it is cheap, and it works on a hot or rainy day when the hill above doesn't.

Buda Castle Cave Tour

About this experience

Some 3.3 kilometres of passages run under Castle Hill, carved by thermal water and then dug out and joined up over centuries. People used them as wine cellars, a prison, and during the 1944-45 siege as bomb shelters. The Duna-Ipoly National Park manages the cave and runs these tours, mixing geology with the human history. Guests report the guides are funny as well as knowledgeable.

There are two routes. The normal tour covers about 1.5 km in roughly 1.5 hours and meets at the Holy Trinity Column, opposite Matthias Church; it is for ages 12 and up. The short tour covers 0.6 km in about 45 minutes, starts at the cave entrance at Dárda utca 2, and takes children from 5. Check which one you've booked, because the meeting points differ. According to the national park, tickets are sold online only and there is no ticket desk at the entrance.

Practical points: it's 12 C all year, the paths are paved and lit, groups go up to 25, and there is no phone signal underground. Food, prams and video recording are not allowed. This is not the old Labyrinth attraction with its wax figures. It is a guided cave visit, and a good one.

  • Medieval cellars and passages dug by hand
  • The wartime story of the shelters under the hill

Vicky, our tour guide, was excellent and very knowledgeable. What I like most, though, was her sense of humor and the way she always tried to make the tour more fun and enjoyable. Overall it was a wonderful experience and I would definitely do it again

What a fascinating and interesting tour. Hard to believe over 1000 people lived underground. Lazlo (apologies if wrong spelling), was fantastic and very informative.

Tips before you book

  • Bring a warm layer even in August. It's 12 C down there, and you'll stand still for stretches.
  • Wear closed shoes and clothes that can get a little dirty. The walls can be damp.
  • Check your meeting point on the ticket. The long route meets at the Holy Trinity Column, the short one at Dárda utca 2.
  • Buy before you go up. Tickets are online only, and popular slots in summer sell out.
  • Combine it with the WWII siege tour only if you love the subject; they share part of the same cave system.
