What is there to do?

Did you know that the Black Chasm Cavern was designated a National Natural Landmark back in 1976? That's because it is considered a "nationally significant natural area" - and so well worth the visit!

This natural wonder in California was created over millions of years, and boasts a number of impressive and enchanting formations that kids will think they are right out of a fairy-tale. 

Those iconic stalactites and stalagmites fill the caves, as do flow-stones. However, it's the rare helictite crystals which the Black Chasm Cavern are famous for - so make sure you keep an eye out!

The walking tour is lit, warm and suitable for all ages, with environmentally friendly observation platforms and walkways

In addition to the tours, there is the Labyrinth Tour. This is a physically challenging, yet fun surface tour where you can explore the stunning rock outcroppings in the forest surrounding the cavern. Perfect for kids over 8 years and is great for about 3 hours of entertainment!

Here, you can hike, climb, crawl and slide under and over those mammoth rock sculptures that were created over 100 years ago! These occurred when the gold miners use hydralic mining techniques, and washed away the soil exposing the rock underneath.

If you are uncomfortable with being underground, or had a great time and want the fun to continue, the Black Chasm Cavern has above ground fun too! Adults and kids alike love the gemstone mining - there's always excitement when you find that first sparkling gem! The water flumes are right outside the Visitors Center, and everyone is guaranteed to find a REAL gemstone! Great for starting that rock collection!

Don't forget to visit the Visitors Center too! Here you can find all the information you need on the history of the mines, and the mining itself.
