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.

We took our three grandchildren here and we all enjoyed the tour. The cavern is large and one goes down on stairs to the bottom. This cavern is a bit smaller than the Mercer Caverns in Calaveras County but equally as enjoyable... There is a area outside where our grandchildren (ages 7,9, 11) could pan for minerals and fools gold(... More

Went on a great tour into the Cavern that is quite amazing. Picture taking is welcome and the tour is approx 1 hr long. Picnic tables are close to the parking lot so bring a lunch or snack to have prior to driving home. Would be nice to have a EV car charger for this attraction.

Really enjoyed seeing this cave. It's a cave I've returned to visit several times. I live in this area and whenever we have visitors from out of town, this is one of the sites we take people. It's rarely crowded and the owners are great. Very helpful in describing all the rock formations. Don't forget to bring a jacket because... More

This is one stop you have to make with the family. Set in a remote area, the scenery surrounding the caverns are beautiful with trails available for hiking as well. The tickets are purchased in the gift shop which has a nice assortment of geological knick knacks for purchase. The tour leaders are young and clearly enjoy giving tours. We... More

The Cavern is accessed down 165 steps, it is small but worth every penny. Accented by blue marble and wonderful formations we enjoyed out tour. The guides are friendly and informative. We even had our picnic lunch outside under the trees. The gift shop was great too. Senior rates if you ask.
