Darrington is located along State Route 530, which travels west towards Arlington and north to State Route 20 at Rockport. The highway carries a daily average of approximately 3,300 vehicles west of the town and 2,300 vehicles north of the town towards the Sauk-Suiattle Reservation. Darrington has a third highway connection through the Mountain Loop Highway, a backcountry scenic byway that runs south through the Cascades and west to Granite Falls. It is closed in the winter and is considered unsuitable for commercial traffic, in part due to a dirt and gravel section.
