Overview

Granite cliffs with spectacular rushing waterfalls define Hetch Hetchy, once considered a rival to Yosemite Valley during the late 1890's. In 1938 the O'Shaughnessy Dam turned the Tuolumne River into an eight-mile long reservoir to meet the water needs of San Francisco.

The hike to the base of Wapama Fall is an easy 5-mile trip, but you can continue for approximately 8 more miles on a moderately difficult trail to Rancheria Fall. The 12-mile Lookout Point hike takes you to overlook the Hetch Hetchy Valley, and the most difficult hikes lead to Smith Peak or down more than 1200 feet to the Tuolumne River.

Trailhead

From California 120, take the Hetch Hetchy turnoff to the end of the parking lot above the dam and reservoir. Vehicles over 25 feet are prohibited due to road conditions.
