Welcome! Friends of the Centennial Trail advocate for maintenance and completion of the Spokane River Centennial Trail, connecting trails and adjacent park lands. This 63 mile, two-state National Recreation Trail is a treasure for Inland Northwest residents and visitors. Over 39 miles in eastern Washington span from the state line through Liberty Lake, Spokane Valley, Spokane, Riverside State Park and end in Nine Mile Falls, Washington. Heading east from the state line, 24 miles extend through Post Falls and Coeur d’Alene, Idaho.
Centennial Trail initial construction period between 1989-1991 was in celebration of the Washington State Centennial. The Trail generally follows the contours of the Spokane River, allowing access for many types of outdoor non-motorized recreational activities. All miles are completely paved; thirty seven miles are safe, separated Class 1 Trail.
A Washington State Discover Pass is only required on vehicles parked at Centennial Trail “Trailheads” within Riverside State Park. The pass is not required at other trailheads (Maringo, Islands, Barker, etc.).
