If you have a craving for caving, then this tour company will fill that hole in your life. They have been providing this tour since 1994. Spend 3 to 3 1/2 hours traipsing through the second-longest cave of Hungary, the Pál-völgyi-Mátyás-hegyi cave system. Most of it is situated under Budapest. Following a professional caving guide, you will explore the natural untouched cave system. The guides explain the formation of the Budai Mountains, the cave formations, and fossils along the way. All the necessary equipment is provided with the tour: protective clothing, helmet, and headlamp. A changing room is available at the cave entrance. Crawling, scrambling, and hunkering down will be done many times during the tour, but no previous experience in caving is needed. Minimum age is 6 years, but no upper age limit. It is not recommended for those who are claustrophobic or unable to squeeze through tight places. Three English tours a week or a special tour for a minimum of five people are offered.
