About Ninemile Falls
Ninemile Falls tumbles along the Spokane River, its name recalling the roughly nine-mile distance to Spokane. The waterfall sits within the Colville Reservation (land owner: DESG; designation: TRIB) and is managed by tribal authorities (Manager: TRIB). The falls are associated with a small dam complex on the river, so flows and river conditions can change with water-management operations — a dramatic backdrop for photography and river views when conditions allow. Visitors looking for a short outing will find a moderate hiking route that reaches viewpoints overlooking the river and falls. Plan for a roughly 2.4-mile out-and-back route with about 350 feet of elevation gain; because the site is on tribal land, observe posted access rules and any guidance from tribal managers to keep visits respectful and safe.
The Setting
Ninemile Falls sits at 1,342 feet within Colville Reservation, fed by the Sanpoil River, in the foothills of Washington.
