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, flowstones 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. Everyone is guaranteed to find some real gemstones; the perfect start to a rock collection! Try our new incredibly popular geode cracking too!
Our new 3,000 square foot Visitors Center provides information on Black Chasm Cavern's connection to the Matrix trilogy, and displays props from the movies: huge manufactured stalagmites from the Zion set. In addition, information is displayed on the discovery and mapping of numerous fragile, highly decorated, small chambers in Black Chasm Cavern by a team headed by Dr Hazel Barton who starred in the iMax movie "Journey into Amazing Caves".
The Walk Tour
The 50-minute Landmark Walk Tour follows a series of environmentally friendly platforms, stairs and walkways, designed to give the best views of the cave without compromising the naturally pristine environment. This beautiful tour shows off some world class formations, including vast arrays of rare helictite formations. Currently, the cave tour culminates in a visit to the Landmark Room, the location of the greatest collections of sparkling helictite crystals.
For safety reasons, we do not recommend that babies be carried into the cave in backpacks. Front packs are okay, but be sure to protect the head in low areas.
This cavern tour is suitable for the entire family and makes an excellent school, scout or church field trip.

The Zen Garden Hike
Black Chasm Cavern is situated in an incredibly beautiful environment that is a transition zone between two ecosystems. This means it has an extra wide variety of flora and fauna. In addition, the area was hydraulically mined over 100 years ago. As the water washed over the land, stones were exposed, creating a landscape of standing stones that are fun to navigate through, and very picturesque. We liked the area that had been mined so much that we built a trail to it and named it the Zen Garden. The trail also takes you through a grove of beautiful madrones. The hike is free and self guided. Just pick up a map from the Visitor Center, and take your time exploring and enjoying the trail.
