Tumwater Penstock Trail and Bridge

The former pipeline bridge is a distinctive feature of a route that connects industrial heritage with the canyon’s rushing-water scenery.

Check current trail conditions before setting out, particularly during spring high water when parts of the route can flood. Stay on authorized paths and keep away from dangerous river edges. The photograph shows the historic bridge on the route; the linked OSM feature marks this crossing within the wider walking trail.
