Trails: Hidden in Yosemite National Park’s peaceful northwest corner, Hetch Hetchy Valley is a treasure worth visiting in all seasons. Located at 3,900 feet, Hetch Hetchy boasts one of the longest hiking seasons in the park and is an ideal place for thundering spring waterfalls and wildflower displays. High temperatures prevail in summer months, but that is a small price to pay for the reward of vast wilderness filled with stunning peaks, hidden canyons, and remote lakes.
Directions: The Hetch Hetchy Road begins just outside of the park on Highway 120, near the Big Oak Flat Entrance Station. This road has seasonal hours corresponding roughly with daylight hours. There is no access to Hetch Hetchy trailheads when road is closed.
