Welcome to Friends of the Centennial Trail

Friends of the Centennial Trail advocate for maintenance and completion of the Spokane River Centennial Trail, connecting trails and adjacent park lands. This 64-mile, State Park, two-state National Recreation Trail is a treasure for Inland Northwest residents and visitors. Over 40 miles in eastern Washington span from the WA/ID state line through Liberty Lake, Spokane Valley, Spokane, Riverside State Park and 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-eight miles are Class 1 Trail, separated from vehicular traffic.

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.).

*** CENTENNIAL TRAIL ASPHALT OVERLAY PROJECT ***
Beginning Monday April 15, 2024, State Parks will commence an asphalt overlay project on the first 14 miles of the Spokane River Centennial State Park Trail. This project includes an 1.5" asphalt overlay, safety improvements, and kiosk renovations to upgrade the trail experience for our community and visitors. The anticipated completion date is early September.

For the safety of the public and people working on the project, the Centennial Trail from the Washington/Idaho state line to the Donkey Islands trailhead in Millwood will be closed during construction.  Closed trailheads include:
State Line  
Harvard Road
Barker
Old Mission
Mirabeau
Islands
Donkey Islands at Maringo

Please help spread the word about this essential trail improvement.  Regular updates will be posted on the project website.
