About Pumice Flat Group Camp

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.


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.


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.

Beautiful Campground!

Pumice flat was absolutely gorgeous! Very quiet campground with clean restrooms and water. The River runs right through the campground with several access points for fishing. I had No cell service in the Reds meadow valley. Tons of trails in the area such as Rainbow falls and the Devils postpile which is a National Monument. You can see them both on a 4 mile loop which also stops in Reds Meadow that will add .7 to your hike. The pct also runs through Reds Meadow if you’d like to hike a short section on that. Reds Meadow has a cafe and general store with WiFi and all the amenities. You’ll need to purchase and adventure pass on your way into Reds Meadow valley for 10$ either at the guard station on your way into the park or from the Mammoth mountain adventure center. Please remember to properly store food in provided bear boxes while camping for this is very active bear country.
