Yosemite is so large that you can think of it as five parks. Yosemite Valley, famous for waterfalls and cliffs, and Wawona, where the giant sequoias stand, are open all year. Hetch Hetchy, home of less-used backcountry trails, is most accessible from late spring through early fall. The subalpine high country, Tuolumne Meadows, is open for summer hiking and camping; in winter it's accessible via cross-country skis or snowshoes. Badger Pass Ski Area is open in winter only. Most visitors spend their time along the park's southwestern border, between Wawona and Big Oak Flat Entrance; a bit farther east in Yosemite Valley and Badger Pass Ski Area; and along the east–west corridor of Tioga Road, which spans the park north of Yosemite Valley and bisects Tuolumne Meadows.
