Falling 2425 feet (730m) in three sections, Yosemite Falls is the tallest waterfall in North America and the fifth tallest in the world. During winter, a cone of frozen mist forms at the base of Lower Yosemite Falls. A strenous hike takes visitors from the valley floor to the precipice of the falls, offering impressive perspective of the falls and their enormity relative to the valley itself. Yosemite Falls flows year round; May and June are most impressive, while flow slows to nearly a trickle during winter months. Here is a panoramic view and QTVR of Yosemite Falls from Cook's Meadow.
