Whitehorse Regional Trail

​The Whitehorse Regional Trail is currently opened between the Fortson Mill Trailhead to Darrington and we ask that visitors only utilize this portion of the trail until further notice.

The trail is currently impassible from Arlington to Trafton due to a landslide and will be closed indefinitely until engineers can assess earth movement that is occurring above and below the trail.

​Project Description



Spanning 27 miles between the City of Arlington and the Town of Darrington, the Whitehorse Regional Trail follows the path of the former BNSF railroad through the North Stillaguamish River Valley. The trail meanders through the valley from its junction with the Centennial Regional Trail in Arlington, frequently paralleling SR 530 and the North Fork Stillaguamish River. The backcounty corridor, rewards visitors with picturesque, landscape views of forests, farmland, streams and rivers, and mountain vistas. Currently only a 6 mile portion of the trail from Darrington to Swede Heaven Road is open to the public.

Whitehorse Regional Trail development will occur in three phases.
