Black Chasm Cavern

Black Chasm Cavern - (866) 762-2837
Located here in Amador County, just outside the quaint village of Volcano, Black Chasm Cavern was designated a National Natural Landmark by the National Park Service in 1976 after being recommended by local members of the National Speleological Society, and as such is considered a "nationally significant natural area.”

Visitors to the cave are enchanted by the beauty of a wide variety of formations including stalactites, stalagmites, flow-stones and the vast arrays of rare helictite crystals, for which Black Chasm Cavern is justly famous. Above ground, kids love our Gemstone Mining at our mining flumes right outside the Visitors Center.

On the 50-minute guided walking tour, descend a series of stairs and walkways that loop around the formation covered caverns walls. Here, flowstone interspersed with stalactites, draperies and helictites compete for space above the stairways. In the Colossal Room, a platform seemingly suspended in midair hangs above a 80-foot drop to small glimpses of the jewel-like Lake Reflection below, made bright turquoise by naturally occurring calcium bicarbonate.

Visit the 3,000 square foot visitors center and gift shop with displays from the Matrix movie trilogy (Black Chasm was the inspiration for the huge cavern set in the second & third movies). Learn about the recent exploration & mapping of the cave, and browse the science, nature, and souvenir merchandise, including a large selection of minerals to start or expand upon your gem and mineral collection.
