Columbia Slough Watershed Council


Walking & Biking

Whether you enjoy exercise by foot or on a bike, you have a slough of options with the region’s evolving 40-mile loop (150-mile system) of walking and bicycle paths that connects trails through the Columbia Slough.

An Evolving Trail System

This interconnected system will eventually include a walking path along the entire Slough, and bicycle-pedestrian trails along roadways stretching from Kelly Point Park east to Sandy River Gorge and south to the Springwater Corridor.

40-Mile Loop Trail Map

The 40-Mile Loop Trail is a century long effort to build a comprehensive trail system through and around Portland.

The planned loop trail has lengthened to more than 140 miles to include all of Multnomah County and to connect more than 30 parks. The trail connects parks and locations along the Slough and along the Columbia, Sandy, and Willamette Rivers and Johnson Creek in an almost continuous loop.
