American Dimond O Camp Ground

Dimond O Campground is a U.S. Forest Service campground in the Groveland Ranger District of Stanislaus National Forest, close to Yosemite National Park's Big Oak Flat entrance and the Hetch Hetchy area. It sits at roughly 4,706 feet elevation along the Middle Fork Tuolumne River and has 26 campsites, including 4 tent-only sites, with paved parking spurs and accessible vault toilets. Sites are first-come, first-served and cash-or-check only — no credit cards are accepted at the campground — with fees generally between $30 and $60, and reservations available up to six months ahead through Recreation.gov. Nearby trails include Carlon Falls, and the campground has recently reported limited potable water availability, worth checking before a stop.
