The Spokane River Centennial State Park Trail runs about 40 miles across eastern Washington from the Nine Mile Falls area through Spokane to the Idaho border. Pick a section for walking or riding. Wildfire recovery has closed part of the route in Riverside State Park, and sewer work affects access near Mission Park.

Choose a Spokane River section

For a ride near the Idaho line, start at Gateway Regional Park. For a downtown walk, use Riverfront Park beside the upper Spokane Falls. The section through Riverside State Park has ponderosa pines and basalt canyon scenery, with an active closure to check before setting out.
