Sentinel Fall, Cascading waterfall in Yosemite Valley, California, United States
Sentinel Fall is a waterfall in Yosemite Valley consisting of six major cascades that flow down a steep granite cliff face, dropping approximately 1,920 feet total. The falls sit prominently along the valley's eastern side, next to a distinctive rock formation that gives the waterfall its name.
The waterfall takes its name from the nearby Sentinel Rock, a prominent granite monolith that stands like a guardian at the eastern entrance of the valley. Early explorers who documented Yosemite Valley applied this descriptive name based on the rock's striking appearance overlooking the landscape.
Photographers and naturalists gather at Sentinel Falls during spring months to document the transformation of winter snowmelt into powerful water streams.
The waterfall can be viewed from several roadside pullouts and viewpoints throughout the valley, with particularly good views from the Four Mile Trail parking area and overlooks near the upper falls area. Plan your visit for midday when sunlight illuminates the cliff face and brings out the spray and movement of the cascades.
The falls undergo dramatic seasonal shifts, freezing into ice columns during winter and completely drying up by midsummer. This transformation means visitors at different times of year see entirely different water conditions and visual effects.
