The Caribou Wilderness is a federally designated wilderness area created by the Wilderness Act of 1964 and is part of the National Wilderness Preservation System. It is located 60 miles (97 km) east of Redding in the state of California, USA. The Caribou Wilderness comprises 20,546 acres (83.15 km2) and is adjacent to the east side of Lassen Volcanic National Park. Both the park and the wilderness are within the Lassen National Forest. The U.S. Forest Service manages the wilderness.
Elevations range from 6,400 feet (2,000 m) to 8,374 feet (2,552 m).
21 of Caribou's lakes are stocked by air with Rainbow trout. Black-tailed deer and black bears along with squirrels, chipmunks, and the protected (from hunting) pine marten live here. There are bald eagles and ospreys overhead, mergansers and grebes on the ponds and lakes.
