California Rockhound Locations

California is another great state to go digging for rocks and crystals in. Most of the mines and dig locations will be off of I-15. The north has plenty of great locations and the southern part of the state is not far behind. You’ll be able to dig and collect precious and semi-precious gemstones without leaving the state.

There are quite a few locations to dig for crystals, agate, and jade in California which makes listing all of them fairly difficult. With that being said, I’ve compiled a list of sites for you to visit and provide feedback.

If you know of a location and are willing to share with us then contact me directly and I’ll add it to the list. I’d be happy to add your contact details as well if you’d like to lead a group.
