Little Yosemite Valley is a smaller glacial valley upstream in the Merced River drainage from the Yosemite Valley in Yosemite National Park. The Merced River meanders through the 3.5 mi long flat valley, draining out over Nevada Fall and Vernal Fall before emptying into the main Yosemite Valley. It can be reached by a day hike from the main valley, and is the most popular area in the Yosemite Wilderness. The Valley provides access to nearby destinations such as the back side of Half Dome, Clouds Rest and the High Sierra Camp at Merced Lake.
Little Yosemite Valley is a tread on the glacial stairway of the Merced River that runs from Yosemite Valley up to Mount Lyell, gaining some 7,600 ft of vertical elevation over 21 mi and is situated some 2,000 ft in elevation above Yosemite Valley proper.
