Mammoth Lakes is part of Yosemite National Park, a UNESCO World Heritage Site located in the Sierra Nevada Mountains in east-central California. Yosemite is internationally recognized for its spectacular granite cliffs, waterfalls, clear streams, giant sequoia groves and biological diversity.
Mammoth is famous for its stunning hiking trails and crystal clear lakes, excellent skiing in wintertime, and a vibrant music and arts scene year-round. Physically fit travelers will enjoy hiking Yosemite’s many trails and footpaths. Check with rangers for trail conditions; snow and hazards from falling rock close many trails in winter. No permits are required park-wide for day hikes. The valley also offers some of the most challenging and spectacular rock climbing in North America, with vertical faces more than 3,000 feet tall.
