There are three publicly accessible caves belonging to the largest cave system in Hungary. They are all situated in Budapest's 2nd district, called Rózsadomb, which is located in the north-western part of the city (on the Buda side). They can be reached by public bus line no. 65.
The "main" one is called Szemlö-hegyi-barlang ("Freckle hill cave"). It can even be visited by wheelchair users.
Address: Pusztaszeri út 35 / every day besides Tuesdays, tours every full hour
A second one is called Pál-völgyi-barlang ("Paul valley cave"). It requires quite some physical conditions, as there are steep ladders to be managed.
Szépvölgyi út 162 / every day besides Mondays, with tours starting at quarter past.
And then there is the Matyas cave, which can only be conquered by experienced cave climbers.
The labyrinth of caves and tunnels which stretch for over 10 kilometres beneath Castle Hill are said to have been joined together by the Turks during the middle ages for military purposes. In the 17th century, parts of the catacombs were used to store wine. More recently, the immediate area under ?ri utca served as an air-raid shelter during World War II. Today, about 1.5 kilometres are open to the general public, with an area of the labyrinth set aside for a waxwork exhibition on early Hungarian history.
Unfortunately, there's no way of visiting the caves unless you pay to see the exhibition (which we found disappointing and pricey). One plus point however, is the Labyrinth caf? which has live music performances during the summer from blues and jazz artists. Guided tours of the caves - which start every 10-20 minutes - are given in four languages including English
Explore the caves in Budapest! It's unusual to see the caves in megapolis.
The Palvolgy Cave is located on Buda side. From the metro station Moskva Ter take a tram 4 or 6 to the end stop of the tram 17 (before the Margit bridge), take a tram 17 to the end station of the bus #85 (I don't remember exactly) and then take a bus to the Palvolgy cave. Or you can take a tram 4 or 6 from the metro station Nyugaty to the end stop of 17th tram (after Margit bridge) and then take a bus.
It's about +10C inside - don't forget a warm sweater!
This hardcore cave tour was one of the highlights of our trip. If you are out of shape, afraid of VERY small spaces, really overweight, than you might not like it. The tour guide suits up the group in overalls and helmets, then leads you on a wild trip through caverns and the tiny passages that connect them together. I squeezed through holes that I never thought possible! Usually there are alternate routes, but one slightly over weight person had to literally pulled through a very tight passage. The guide is very funny and professional and it is amazing seeing these caves how real cavers see them - on thier hands and knees half the time!
