Calaveras County Real Estate Information Center

Calaveras County is a county located in the Gold Country of the U.S. state of California. Calaveras is the Spanish word for skulls; the county was reportedly named for the remains of Native Americans discovered by the Spanish explorer Captain Gabriel Moraga. As of the 2010 census, the county had a population of 45,578. The county seat is San Andreas. Angels Camp is the only incorporated city.

Calaveras Big Trees State Park, a preserve of Giant Sequoia trees, is located in the county several miles east of the town of Arnold on State Highway 4. The uncommon gold telluride mineral calaverite was discovered in the county in 1861, and is named for it.

Mark Twain set his story, "The Celebrated Jumping Frog of Calaveras County", in the county. Each year, the county hosts a fair and Jumping Frog Jubilee, featuring a frog-jumping contest, to celebrate the association with Twain's story. The California Red-legged Frog, feared extinct in the county by 1969, was rediscovered in 2003.
