The Frank Church-River of No Return Wilderness (FCRONRW) encompasses nearly 2.4 million acres of rugged mountains, wild rivers and alpine lakes. The FCRONRW was designated as wilderness in 1980 and is jointly managed by the Salmon-Challis, Payette, Nez Perce-Clearwater, Bitterroot, and Boise National Forests. It's the largest contiguous wilderness in the Lower 48 and the second largest unit of the National Wilderness Preservation System in the Lower 48.
