This walk is a relaxed way to visit two caves - the Szemlő-hegyi and the Pál-völgyi caves - with English guiding, avoiding the crowds and noisy school-groups. In addition we will enter into sections which are closed from other tourists. The 2-2,5 hours long tour covers an 1000 meters long underground walk, exploring unique rock formations as the underground flower garden of Budapest, stunning stalactite and stalagmite formations, fossiles and glittering calcite crystals. We will climb more than 400 stairs and a 7 meters long ladder. Join us if you are a natural history lover, if you travel with your adventure-seeker kids, or if you’re just looking for something different from museums and sightseeing.
