Black Chasm was named a National Natural Landmark in 1976 by the National Park Service for its outstanding displays of rare helictite formations. The 50-minute guided walking tour descends a series of stairs and walkways that loop around the formation covered caverns walls. Here, flowstones interspersed with stalactites, draperies and helictites compete for space above the stairways. Above ground activities: gemstone mining, nature hike, picnic tables. School program available. Open every day, year round.

The tour was just a walk down into a cave, where the tour guide spent at least 15 minutes explaining how the stalactites grow upwards. Pretty boring, actually. Children under 12 might have a hard time standing still or keeping quiet while the tour is...More

With all the caverns you can explore this one is one of a kind. It is small, local and has Helictite Crystals which are found in only a few other caverns in the United States. They are worth the trip. The tour guides are local...More

Yes, a light jacket is called for and sneakers are a must. Steps can be damp from cave moisture and it is a 'climb' up and down. (although your guide offers ample stops while describing cave wonders)
