Palouse River Centennial Trail Adventures

The Palouse River Centennial Trail extends approximately 30 miles, linking the cities of Pullman and Moscow, running through the Palouse region of southeastern Washington. This trail is built on a historic railroad grade that originally connected the Spokane, Portland and Seattle Railway, providing a relatively flat and accessible route through the undulating hills and farmland characteristic of the Palouse. The region is known for its rich agricultural heritage, with fertile lands producing wheat, legumes, and barley, visible along the route as expansive fields and gentle hills.

Ecologically, the trail corridor passes through a combination of cultivated lands, riparian zones along portions of the Palouse River, and patches of native shrub-steppe habitat. Wildlife sightings may include mule deer, various songbirds, raptors, and abundant wildflowers in spring and summer. Hikers and bikers utilize the trail year-round, attracted by its well-maintained surface, natural scenery, and connections to parks, small towns, and recreational facilities.

Historically, the trail commemorates the region’s railroading past and was developed as a centennial project for Whitman County. It is operated and maintained by Whitman County Parks and Recreation and serves as a recreational and commuter artery for local residents and visitors alike. Key landmarks include the historic railroad bridges, the riparian areas near the Palouse River, and access points near both Pullman and Moscow, which provide amenities, restaurants, and cultural attractions.

The trail’s gentle grades and smooth surface make it suitable for family outings, casual rides, and fitness enthusiasts. Seasonal changes offer diverse experiences: lush green landscapes in spring, agricultural harvest views in fall, and quiet, cooler winter days. The Palouse River Centennial Trail is an accessible example of rails-to-trails conversions that enhance outdoor recreation opportunities in rural Washington.
