Climb and crawl through Budapest’s longest cave system on a caving experience in the Danube-Ipoly National Park. Discover the source of Budapest’s hot springs, and marvel at the limestone rock formations left behind by geological activity. Prepare yourself for something active! We will visit a natural labyrinth system where we will often have to clamber up steep walls and creep through narrow passages. You will see a very unique place if you are ready to make efforts off the beaten track!
