Hetch Hetchy Trailhead

5.0Free

Explore scenic reservoir trails and dramatic waterfalls in quiet northwest Yosemite.

Situated beside the O'Shaughnessy Dam in Yosemite National Park, the Hetch Hetchy Trailhead leads hikers along a pristine reservoir framed by towering granite domes. Popular routes take visitors through a rock tunnel and toward impressive cascades such as Wapama Falls and Tueeulala Falls. It provides a peaceful, less-congested alternative to the bustling sights of Yosemite Valley.

History

The Hetch Hetchy Valley was once a lush, beautiful glacial valley similar to Yosemite Valley. In the early 1900s, it was dammed to create a water supply for San Francisco, igniting a significant conservation debate that continues today.

Quick tip: Wear sturdy footwear with good traction, as spray from Wapama Falls can make footbridges wet and slippery during peak snowmelt.
