Mark O. Hatfield Wilderness

Mark O. Hatfield Wilderness spans 65,434 acres of federally protected backcountry in Oregon, managed by the Forest Service. It is a true primitive wilderness—no roads, motors, or mechanized travel are permitted. This is backcountry on foot only, where solitude and self-reliance are the defining features of a visit.

Hiking and backpacking are the primary ways to experience the landscape. The wilderness offers remote trails and campsites for those seeking to escape developed recreation areas. Access is typically seasonal, with summer and early fall providing the most reliable window for travel. Spring and late fall trips are possible but come with variable conditions.

Visitors must follow Leave No Trace principles and wilderness regulations: camp away from water sources, pack out all waste, and travel quietly to preserve the primitive character. This is not a place for casual day-use—plan for multi-day trips and come prepared for isolation, variable weather, and self-guided navigation. Respect for the wilderness designation is essential; the area exists to protect wild character and non-motorized recreation.
