Inyo Craters

Six hundred years ago, a massive explosion heated rock and ground water, causing a large blast zone. Three craters were formed. Today, snow melt and rainwater create emerald green pools in the craters. Accessibility: 1.4 miles (2.25 km) round-trip uphill hiking trail. Directions: From the Mammoth Scenic Loop follow signs to Inyo Craters. Take 1.3 mile (2km) unpaved road to trailhead.

As of August 1, 2022, to ensure public safety Inyo National Forest officials are temporarily closing the entry roads, trails, and facilities at the Inyo Craters site, located on the Mammoth Ranger District during the month of August.
