Yosemite National Park once included two spectacular glacier-carved valleys – Hetch Hetchy and the Yosemite Valley. Hetch Hetchy Valley, however, lies underwater and is unavailable to park visitors.

Restoring Hetch Hetchy Valley to its natural splendor provides the opportunity to recreate an environment as never before.

We have launched our Walk The Valley campaign— encouraging people to make a pledge to one day walk the Hetch Hetchy Valley when it is restored. Make the pledge & encourage others to do the same.
