Unique experience to see the "other" side of Budapest. Guide was very accommodating of our group, including one member with claustrophobia. There are often several routes to advance to the next space, so the more adventurous can go one way and others have a different option. It is very warm in the cave compared to outside during the winter, so a Tshirt is fine as thick coveralls are provided. At one point we sat in a large room in the cave and turned off all our headlamps and kept silent for a while - very cool experience with no light or sound. Highly recommended for families.
