The Columbia Plateau Trail is a 130-mile-long (210 km), 20-foot-wide (6.1 m) corridor in eastern Washington state along the abandoned right-of-way of the former Spokane, Portland and Seattle Railway. It runs between Cheney, Washington and Pasco at the confluence of the Snake River and Columbia River. It passes through parts of five counties in southeastern Washington. It is open to public for recreational use as part of the Washington State Park system.
