The Shoshone Ice Caves claim to fame is their ability to maintain cold temperatures in the midst of an arid desert and to actually form ice deep in the lava tubes below the desert surface.

They are unique in that in an area that typically reaches temperatures over 100 degrees during the summer, the interior of the caves' temperature ranges between 18 to 33 degrees. If you plan to tour the interior of the caves, come with socks, shoes and a coat.

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. The Caves are open daily during the summer months and are a kid-friendly attraction. On a guided tour, travelers will be taken into a series of lava tubes in which the cold air currents moving through them cause the water below the surface to freeze into ice. The actual tour of the Ice Caves takes around one hour, but is well worth the time. As a bonus, it gives the traveler a reprieve from the intense heat of the desert during the summer.

A museum contains Indian artifacts, gems, and minerals of local and world interest.
