Wilderness
Six Rivers National Forest boasts access to six Wilderness Areas that provide opportunities for solitude and primitive recreation. The Forest shares management of four wilderness areas—the Siskiyou, Trinity Alps, Yolla Bolly–Middle Eel, and Marble Mountain Wilderness Areas—with nearby forests, and solely manages the North Fork and Mount Lassic Wilderness Areas. If you have questions about a specific wilderness experience you are encouraged to call one of our forest offices.
