Class III-IV Merced River, CA

From its source on the south side of Mount Lyell at 13,114 feet, through a glacially carved canyon within Yosemite National Park, the river flows downstream to Lake McClure Reservoir. Seventy-one of the total length of 79 miles are protected with wild and scenic river designation.

The Merced flows through exceptional scenery—glaciated peaks, lakes and alpine and subalpine meadows—in alternating pools and cascades. Wildflower displays are spectacular.
