Nestled in the Eastern Sierra and rising from the village of Mammoth Lakes, Mammoth Mountain is a symbol of high-altitude recreation. The resort spans over 3,500 acres of ski terrain, accessible from its base at about 7,800 ft to a summit near 11,059 ft, serving world-class snowboarding and alpine skiing. In summer, the area's glaciers—particularly on the north side—permit summer skiing and snowboarding, while the surrounding forests and alpine lakes are magnets for hiking, mountain biking, and trail running. The resort is connected by a comprehensive lift system and offers terrain suitable for all skill levels, plus mountain biking services that include lift-assisted descents. Beyond the lifts, the region provides guided activities, fishing in nearby lakes, and access to the broader Inyo National Forest and Mono County trail networks.
