3. John Muir Trail
This 210-mile trail winds through the High Sierra wilderness. For 160 of those miles, the trail is part of the Pacific Crest Trail. You will be mostly above 8,000 feet in elevation for the hike, which begins at Yosemite National Park, passes through Inyo National Forest, Ansel Adams Wilderness, Kings Canyon and Sequoia National Parks and ends at the summit of Mount Whitney, the highest point in the continental U.S.
