Three Brothers Lookout Trail

Three Brothers Lookout Trail is a multi-peak ridge hike in Washington’s Teanaway area, built around the former fire lookout site at the end of a long, demanding ridgeline effort. The route is commonly completed as an out-and-back or traverse-style day and typically takes experienced hikers most of a workday.

The objective includes summiting several high points along the ridge—most notably Three Brothers Mountain—before continuing on to the old lookout site. Expect repeated steep climbs, faint tread segments at times, and plenty of navigation work along exposed ridgelines.

Route length and effort add up fast: it’s commonly around 15 miles with roughly 6,500+ feet of elevation gain, which matches its “moderate” label in the map data but still feels serious due to continuous altitude accumulation.

A frequent way to build the day uses the Stafford Creek Trail to reach the Three Brothers area, then connects onward along ridge travel to reach the lookout site. In practice, linking segments can require leaving the established tread and finding your way between high points.

Conditions on this kind of ridge route can turn route-finding into the main challenge—especially in snow years or when patches linger near saddles and traverses. Plan on needing a reliable offline map/GPS track and being comfortable with route-finding off continuous trail.

The mapped version of Three Brothers Lookout Trail follows a ground surface path/track corridor and is labeled in the underlying data with the alternate name Negro Creek Road (ref NF 7322-485 / TR 1211).
