Crystal Lake Cave

The cave is three-quarters of a mile of well-lit passageways. There are intricate formations and an underground lake. This is one of the few caves in the country that contain formations known as athodites - a rare form of cave crystals. Competent & friendly tour guides lead visitors through this wondrous cave on an exciting half hour to 45 minute adventure. Guests are advised to bring a jacket as temperatures are 52 degrees Fahrenheit inside Crystal Lake Cave year around.
