Hiking & Backpacking in Mammoth Lakes

Hiking in the Eastern Sierra is spectacular year-round. In spring, the sharp and craggy granite peaks of the Sierra Nevada Range form a dramatic backdrop for meadows brightly colored by wildflowers.

In summer, you'll find secret alpine lakes, lush aspen-lined streams, and forested hideaways tucked away in the mountains. In fall, early snow in the high country contrasts beautifully with the vibrant golds and oranges of aspens and willows.

Mammoth Lakes sits inside two million acres of the Inyo National Forest, with hundreds of miles of trails covering every difficulty level—from short, easy walks to multi-day backpacking routes into the Ansel Adams Wilderness and along the Pacific Crest Trail and John Muir Trail. Many trailheads are accessible by the free town shuttle, so you don't need a car to get out on the trail. Browse the full trail network at mammothtrails.org.

All hiking in Mammoth Lakes starts at elevation—town sits at 7,880 ft and most trailheads start above 8,500 ft. First-time visitors should read our high altitude tips before heading out.
