Pumice Butte is a 3.9-mile out-and-back hike in the John Muir Wilderness, within the Mammoth Ranger District of Inyo National Forest in California. The trail sits at about 9,000 feet, with the high point reaching roughly 9,500 feet. The Forest Service manages the land, and the route is rated hard with a one-way climb of about 500 feet. The trail is natural-surfaced and accessible only to horses, which are allowed. Bikes are not permitted. The climb is the most comfortable from July through August, when typical averages from a nearby weather station run from a high of about 71°F to 70°F, with lows in the upper 30s. That station sits several hundred feet lower, so temperatures on the butte run a bit cooler. Deer Creek is about half a mile away, and the Pacific Crest Trail passes within about a mile and a quarter. Climbers can head to Crystal Lake Wall, about 1.8 miles out, and Lake George Campground offers a place to camp within about 3 miles.
