This natural wonder is actually a lava tube that is 1,000 feet long, with an ice depth ranging between 8 and 30 feet in height.

Take a tour with the proprietor and learn all about the fascinating geology of the area. Explore the trails but be sure to dress warmly, even during the summer months. Constant below-freezing temperatures make a pleasant contrast to the often scorching summer heat. The ice in the “ice caves” is caused by air currents flowing through the tubes, which causes subterranean water to freeze.

These caves are one of the natural wonders of the world. Trained guides explain the geologic, volcanic, and historical background in these large lava ice caves. A museum contains Indian artifacts, gems, and minerals of local and world interest.
