Tuolumne Meadows serves as a hub for summer backpacking opportunities in the park. Temperatures average 15 to 20 degrees Fahrenheit cooler than in Yosemite Valley, and, at 8,600 feet in elevation, the air is crisp, invigorating, and thin! Tuolumne hikers enjoy a variety of popular routes and many of the trailheads are within a short distance of each other. Trails range from just a few miles to Sunrise Lakes to thousands of miles on the Pacific Crest Trail. Remember, any blue sky day can quickly turn ominous and gray. The Sierra are well known for their magnificent afternoon thundershowers; enjoy these from a safe location in good raingear. (The Tioga Road closes due to snow, usually from sometime in November through late May or early June. There is no overnight parking on the Tioga Road after October 15, please plan accordingly.)
