Mark O. Hatfield Wilderness

Mark O. Hatfield Wilderness is a 65,434-acre federally protected backcountry area in Oregon managed by the Forest Service. It is designated as true wilderness—meaning no roads, motorized vehicles, or mechanized travel of any kind are permitted. This is primitive country reserved for foot traffic and non-motorized use only.

The wilderness offers hiking and backpacking as its primary recreation. Visitors come for backcountry solitude and immersion in undeveloped forest landscape. The area enforces Leave No Trace principles and all standard wilderness rules: pack out what you pack in, camp away from water sources, use established sites where they exist, and travel lightly on the land.

Access is on foot only from trailheads on the perimeter. The high-elevation terrain and Oregon location mean the best travel window is mid-summer through early fall, when snow has cleared and weather is most stable. Spring and early summer bring mud and lingering snow; winter makes the wilderness inaccessible to most travelers. Plan for a true backcountry experience in a place where the absence of development is the entire point.
