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 back county 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. To view phase information and project maps visit the Snohomish County Parks website.
