Pumice Flat Campground is a scenic, first-come, first-served campground in the Reds Meadow Valley area of Inyo National Forest, near Mammoth Lakes, California. It sits at an elevation of about 7,700 feet in a lodgepole pine forest, surrounded by high mountain peaks and adjacent to two creeks and the Middle Fork of the San Joaquin River.
The campground offers a peaceful, nature-immersed base for exploring the eastern Sierra Nevada, with easy access to Devils Postpile National Monument, Rainbow Falls, the Ansel Adams Wilderness, the Pacific Crest Trail, and John Muir Trail. It is popular with fishermen, families, hikers, and those seeking geologic wonders and stunning landscapes. The area is known for its dramatic volcanic features, meadows, wildflowers in season, and proximity to trailheads (about 20–40 minutes from central Mammoth Lakes, depending on the exact point).
Access is via a narrow, single-lane road (Red’s Meadow Road off Highway 203) that is only open in summer, typically mid-June through early September, though conditions can vary due to snow. A forest service access/amenity fee often applies for driving into the valley.
