History & Background
The Hetch Hetchy Valley was once a rival to Yosemite Valley in beauty, with similar granite cliffs and waterfalls. In the early 20th century, it became the center of a major environmental controversy when the city of San Francisco proposed damming the Tuolumne River to create a reservoir. Despite opposition from conservationists like John Muir, the O'Shaughnessy Dam was completed in 1923, flooding the valley. Today, the reservoir remains a critical water source for the Bay Area and a poignant symbol of the tension between conservation and development.

Bring plenty of water and sunscreen, as shade is limited along the trails.
