About Boulder Falls
Boulder Falls sits tucked into Washington’s Mount Baker National Forest and is managed by the U.S. Forest Service. The falls cascade over a rocky cliff into a small pool framed by old-growth forest, creating a compact but photogenic scene that draws hikers and photographers alike. Access is via the Boulder River Trail (USFS Trail #734), which brings you right to the falls’ viewpoint. The hike to the falls is an enjoyable moderate outing: the route measures about 2.4 miles one-way (USFS GIS records list 2.99 miles) with roughly 350 feet of elevation gain. The USFS classifies the trail as Trail #734 (Class 3) on a native-material surface with typical grades of 12–20%, so you’ll encounter natural tread and some steeper sections along the river corridor. The setting is inviting for a half-day trip and is stewarded as part of the National Forest system, so plan for typical backcountry conditions and pack accordingly.
The Setting
Boulder Falls sits at 1,027 feet within Mt. Baker National Forest, fed by the Nf Stillaguamish River, in the foothills of Washington.
