About
Overview
Pumice Flat Group Camp is located in the Red's Meadows and Devils Postpile section of the eastern Sierra Nevada Mountains, just west of the full-service community of Mammoth Lakes, California.
This group camping facility provides access to some of the most spectacular wilderness in the Sierras and many outdoor activities such as horseback riding, fishing, hiking, photography and geologic study of the dramatic landscape. Devils Postpile National Monument and the famous Ansel Adams Wilderness are nearby for campers to explore.
Recreation
This campground is a great base camp for hiking the area's many trails. Within a few miles, campers will find trailheads to the Ansel Adams Wilderness, Pacific Crest Trail and John Muir Trails. There is a mandatory shuttle that takes hikers to nearby trailheads.
Fishing enthusiasts can try for trout in the lake or the North Fork of the San Joaquin River.
Facilities
The group camp is within the main Pumice Flat Campground, which offers first-come, first-served individual sites. The group area consists of four group campsites, spaced well apart and located fairly close to either creek. Picnic tables, campfire rings and food storage lockers are provided.
The road to the facility is narrow, single-lane and only accessible in summer.
Natural Features
The campground sits in a lodgepole pine forest surrounded by high mountain peaks and adjacent to two creeks. The elevation is 7,700 feet.
The area boasts some very interesting geologic features, including numerous lakes and rugged mountains, which lend themselves well to photography.
Many species of wildlife call the mountains home, such as black bear, mountain lions, mule deer, pine marten, pika, fish and birds.
Nearby Attractions
The Red's Meadow Pack Station and Resort are about 2.5 miles away at the end of Red's Meadow Road. A general store and cafe are available. The trailhead for Rainbow Falls also begins here.
The area is very close to Devils Postpile National Monument and the Ansel Adams Wilderness. Both areas have numerous trails and unparalleled photographic opportunities.
