We are building a system of bridges and trails called the Northern State Trail System, connecting Northern State Recreation Area (NSRA), a Skagit County Park located in Sedro Woolley, Washington, to neighboring properties managed by the City of Sedro Woolley, and the Port of Skagit.
Proposed Trails 2025-2027
On September 27, 2025 we begin work on properties managed by the Port of Skagit and City of Sedro-Woolley to improve trail connections and grow the size of the Northern State Trail System.

An important note! The map of proposed trails (below) includes areas not open to the public. Please do not trespass by attempting to explore these potential routes.
