Rockhounding in California

Updated October 2026

104 mapped spots for rock hunting and rock collecting across 24 counties. California covers a wide range of rockhounding: gold-bearing rivers in the Mother Lode, jade on the central coast, and agate and jasper in the Mojave. Collecting is allowed on most BLM and Forest Service land outside designated wilderness.

Where is the best rockhounding in California?

The best rockhounding in California is at Happy Camp Jade Mines in Siskiyou County (jade, gold), Trinity River in Trinity County (chalcedony, gold), and Glass Mountain in Siskiyou County (obsidian). In total, 104 mapped collecting spots across 24 counties produce jasper, agate, and chalcedony, each listed below with its land access.

Top minerals found in California

Counts reflect how many spots in this list mention each mineral.

Notable areas: Big Sur jade, Mojave jasper, blue chalcedony, gold panning, and limited benitoite access are common California search terms.

Geology behind California rockhounding

California's collecting reflects its tectonic complexity. The Mojave's Tertiary volcanics produce agate, jasper, and chalcedony. The Sierra Nevada foothills hold the Mother Lode gold belt and its associated quartz, schist, and mariposite. The Coast Ranges expose serpentinite and the Franciscan complex, host to jade, nephrite, and rare benitoite. The Klamath and Salmon Mountains contribute garnet schist, gold, and platinum-group placers.

Best regions to focus your search

Mojave Desert & southeast California

Wiley Well, Hauser, Black Hills geode beds, Cady Mountains agate, fire agate at Saddleback Butte vicinity, and jasper across BLM lands east of Barstow.

Mother Lode (Sierra Nevada foothills)

Recreational gold panning on the American, Yuba, Feather, and Mokelumne rivers; mariposite, quartz crystals, and copper minerals in old mine dumps. Stick to legal access points, much of the river bank is private or claimed.

Central Coast (Big Sur, Jade Cove)

Big Sur jade picked from the surf at Jade Cove, hand collecting only below the mean high-tide line within the Monterey Bay National Marine Sanctuary boundaries.

North Coast & Klamath

Beach agates, jade, and serpentine; rough country with active mining claims. The benitoite type locality in San Benito County is closed to public collecting.

Best season

Mojave: October through April. Sierra rivers: late summer through early fall when water is low. North Coast and Big Sur jade: year-round, with fresh material most likely after winter storms move gravel and nephrite in the surf.

What to bring

Mojave desert: gallon-per-person water minimum, spare tire, paper map, sun protection. Mother Lode: classifier, sluice box (legal restrictions apply, see CDFW dredging rules), and recreational gold pan. Jade Cove: snorkel or wade gear and a mesh bag.

Local collecting history

The 1849 California Gold Rush shaped mineral collecting across the West. Big Sur jade became better known in the 1970s, when divers and beach pickers began bringing nephrite out of the surf; the Big Sur Jade Festival still marks that local history.

California rockhounding FAQ

Is rockhounding legal in California?+
Yes on BLM and most USFS land outside designated wilderness. All national parks (Yosemite, Death Valley, Joshua Tree, Sequoia, etc.), the Mojave National Preserve, and California State Parks are closed to collecting. Suction dredging for gold is heavily regulated by CDFW.
Can I take Big Sur jade from Jade Cove?+
Yes, Jade Cove allows hand collecting of jade below the mean high-tide line. You may not use power tools, dig the cliffs, or remove jade from above the high-tide line. The cove sits within the Monterey Bay National Marine Sanctuary, which adds federal rules over the surface waters.
Where can I gold pan in California legally?+
Recreational hand panning is legal on most BLM and USFS land on public stretches of the American, Yuba, Feather, Mokelumne, and Trinity rivers. Avoid posted private property and active mining claims. Suction-dredge mining is separately regulated by CDFW and is currently restricted statewide.
What's the BLM rockhounding limit in California?+
Up to 25 pounds plus one piece per day, with a 250-pound annual cap per person, for common rocks, mineral specimens, and semiprecious gemstones. Petrified wood is capped separately at 25 lb/day and 250 lb/year.
What rocks and minerals can you find in California?+
Common targets include agate, jasper, chalcedony, opal, jade (Big Sur), gold (Mother Lode and Klamath placers), garnet, tourmaline (Pala district pay-to-dig), and aragonite and zeolites in various volcanic exposures.
Where can I go rock hunting in California?+
Rock hunting, rock collecting and rockhounding are the same hobby under different names. 104 spots are mapped in California, 76 of them with public access. San Bernardino County, San Diego County, and Los Angeles County have the most.
Is there gem mining or pay-to-dig in California?+
Yes. 6 fee digs are mapped in California, where you pay to dig and keep what you find: Benitoite Mining Company, Hallelujah Junction, Davis Creek Mercantile, Benitoite Gem Mine, and 2 more. Prices and seasons change, so check with the operator before you drive out.
Where can I dig for crystals in California?+
11 mapped spots in California report quartz, amethyst, or smoky quartz, mostly in San Diego County, Kern County, and Lassen County. Each one is in the list on this page with its land access.

Yes. 1 mapped spot in California reports geodes, mostly in Los Angeles County.
