Hetch Hetchy Reservoir

Located in the northwestern area of Yosemite National Park, Hetch Hetchy Reservoir features dramatic granite cliffs, rushing waterfalls, and peaceful waters far from the park's busiest trails. Framed by the historic O'Shaughnessy Dam completed in 1923, the area offers scenic hiking routes like the trail to Wapama Falls. Its serene environment makes it an ideal destination for visitors seeking spectacular wilderness landscapes with fewer crowds.

History

The reservoir was created in the early 20th century to provide water to San Francisco, leading to significant controversy over the flooding of the Hetch Hetchy Valley, which was once considered as beautiful as Yosemite Valley itself.
