Colossal Cave Mountain Park

In 1923, the first proper tours of Colossal Cave were conducted using ropes and lanterns; today more advanced options are offered. The cave is considered 'dry' or 'dormant' as it is no longer 'growing' crystal formations, due to a lack of water. The preserved stalagmites, stalactites and flowstone are beautiful to see, and the temperature inside the cave is always comfortably warm.
