Yosemite

Yosemite National Park protects a glacier-carved stretch of the Sierra Nevada around Yosemite Valley, Tuolumne Meadows and the Hetch Hetchy backcountry. Reservable campgrounds sit under granite walls on the Valley floor, while Tioga Road opens seasonal high-country camps above 8,000 feet. National forest land around the park adds first-come sites when Valley bookings are full.
