Hetch Hetchy to Lake Vernon Trail, Mountain hiking trail in Yosemite National Park, United States.
The trail extends 23 miles round trip from O'Shaughnessy Dam to Lake Vernon, featuring an elevation gain of 3,723 feet through granite landscapes.
The path begins at O'Shaughnessy Dam, constructed in 1923 to create Hetch Hetchy Reservoir, which supplies water to the San Francisco Bay Area.
The trail traverses territories traditionally inhabited by Native American tribes who lived in Yosemite Valley before the national park establishment.
Hikers must obtain wilderness permits for overnight stays and carry bear canisters, as black bears frequently roam the area searching for food.
The lower elevation of Hetch Hetchy allows for earlier spring access compared to other Yosemite trails, with snow clearing months before higher altitude routes.
