Bucks Lake Wilderness is a 23,958-acre protected area in Plumas National Forest in northeastern California, at the northern end of the Sierra Crest south of Lake Almanor. Protected by the California Wilderness Act of 1984, it preserves a transition zone where the Sierra begins to break apart beyond the North Fork Feather River canyon. Its terrain includes gentler western slopes, glacial cirques, wet meadows, bare granite, and forests of pine and red fir, supporting wildlife such as black bear, mountain lion, deer, eagles, and peregrine falcons. Though named for Bucks Lake, the reservoir lies just outside the boundary and grew after a dam completed in 1928 made it a major recreation destination.
