About

Obsidian Flat Group Campground is a secluded group site in the Inyo National Forest, named after a nearby obsidian lava flow. Situated at 7,800 feet in a pine forest near Mammoth Lakes, California, the campground offers mountain views and a peaceful setting adjacent to Deadman Creek. The single large group site can accommodate up to 50 people with space for five RVs up to 40 feet in length or 15 vehicles total. The site is fairly primitive, equipped with a vault toilet, picnic table, campfire ring, and bear-proof locker for food storage. No potable water is available, so campers must bring their own supply. Strict food storage rules apply due to bear activity in the area. Access is controlled by a security gate; the combination is provided in your reservation confirmation letter. The area provides excellent opportunities for fishing in Deadman Creek, hiking trails including access to the Ansel Adams Wilderness, mountain biking, and off-road vehicle riding. Yosemite National Park makes a great day trip from the campground.
