The first region is Yosemite Valley. Beautiful and majestic, Yosemite Valley boasts some of the most popular trailheads in the park. These strenuous trails lead the hiker up the seemingly sheer granite walls which form the Valley. To reach the top of such spectacles as Half Dome, Yosemite Falls, Glacier Point, and El @Capitan, the hiker will encounter steep terrain, switchbacks, and rapidly changing weather conditions. Spectacular views from the rim of the valley reward the hiker and quickly erase memories of any hardships suffered en route.
In winter and early spring, nearly all of the trails in Yosemite Valley remain open, although some have winter routes designated. In addition to serving the hardy day-hiker, these trailheads provide access for seasoned winter enthusiasts into Yosemite's snow-covered wilderness.
The second region consists of @Tuolumne Meadows and @Tioga Road. Tuolumne Meadows is located at over 8,600 feet in elevation. From Tuolumne, numerous trails lead hikers to lakes, meadows, and beautiful river canyons. More strenuous overnight backpacking trips allow the adventurer access to the northernmost reaches of the Park, the area between Tuolumne Meadows and Yosemite Valley, or along extended wilderness routes such as the John Muir Trail or the Pacific Crest Trail.
Because of its elevation, temperatures in Tuolumne average 15 to 20 degrees cooler than in Yosemite Valley itself. Snow is not uncommon as late as June or as early as September. Peaks, such as Mt. @Dana and Mt. Lyell, retain snow throughout the summer and provide breathtaking views from their bases and summits.
