The Columbia Plateau Trail is a 130-mile-long (210 km), 20-foot-wide (6.1 m) corridor in eastern Washington state maintained as part of the Washington State Park system. The trail runs along the abandoned right-of-way of the former Spokane, Portland and Seattle Railway from Cheney to the confluence of the Snake and Columbia rivers at Pasco, Washington, passing through five counties in the southeastern part of the state. The trail is mostly gravel, except for a 3.75 mile portion between the Cheney and Fish Lake trailheads. Recreational uses include hiking, mountain biking, horseback riding, in-line skating on paved portions, and wildlife viewing. The close proximity of the railroad to the paved portion makes this section of the trail a popular spot for railfanning.
