Tenaya Canyon is a dramatic and dangerous canyon in Yosemite National Park, California, USA, that runs from the outlet of Tenaya Lake 10 miles down to Yosemite Valley, carrying water in Tenaya Creek through a series of spectacular cascades and pools and thence into a deep canyon below Cloud's Rest, a giant granite mountain adjacent to Half Dome. Waterfalls on the creek inside the canyon include Pywiack Cascade (named for Pywiack Dome) and Three Chute Falls, near Mirror Lake.
The top of the canyon can be seen from Tioga Pass Road (Route 120) which goes through Tuolumne Meadows and Tioga Pass. From a roadside view area(Olmsetead) Clouds Rest and Yosemite's signature Half Dome dominate the canyon. At the bottom of the canyon, in Yosemite Valley, lies Mirror Lake accessible by shuttle bus and a short walk.
