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.
I've had the opportunity to experience several caverns throughout the US. Carlsbad in NM for instance. If you are going to Black Chasm and are expecting a cavern of epic proportions you will be disappointed. If, however you want to experience a cool little cavern here in CA then Black Chasm is for you. It's a little tight in places and the hike down is pretty much straight down. The formations definitely make up for it though..
