About

Indian Grinding Rock State Historic Park Campground sits in a scenic valley at 2,400 feet elevation in the Sierra Nevada foothills, surrounded by open meadows and oak woodlands. The campground features 22 established family campsites, each equipped with a fire ring and picnic table, accommodating RVs and trailers up to 27 feet. Two sites are ADA accessible. Token-operated showers, flush toilets, and drinking water are available in the campground. For a unique camping experience, the park offers 7 undeveloped bark houses (U'macha'tam'ma' sites) in a secluded area, each accommodating up to 6 people. These require hauling water and supplies 200 yards or more from parking and have no showers or flush toilets nearby. The bark houses are reservable by calling the park directly. The park preserves the largest collection of bedrock mortars in North America with 1,185 mortar holes carved into marbleized limestone, used by the Northern Sierra Miwok for grinding acorns. Visitors can explore the Chaw'se Regional Indian Museum, view a ceremonial roundhouse still used today, and walk among reconstructed bark houses. The campground closes the fourth Friday through Sunday of September for the Miwok Big Time celebration.
