The Columbia Plateau Trail is 20-foot-wide, 200km long 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 surface is primarily the large ballast rock remains of the former railway, but gravel improvements have been made to several miles at each end of the route.

The Brighouse Boundary Walk is a circular footpath which was created in 1993 to celebrate the centenary of the former Borough of Brighouse. As the name suggests, the walk encircles the town and includes walking across areas of moorland, through local villages and also a crossing the Calder Valley. On Hartshead Moor it links with several other long distance paths, namely the Bronte Way, Calderdale Way and Kirklees Way and Spen Way Heritage Trail.

Portsea Island Loop

The Portsea Island loop is a popular 27 km (16.74 miles) circular route around the perimeter of Portsea Island. The route is circular in nature so can be started (and finished) at any point on the loop and can be ran in either direction due to the complete lack of elevation. It is a mix of coastal paths and tarmac and despite being the perimeter of a busy city, it is still scenic and passes several notable landmarks, nature reserves, a castle and the seafront.

An excellent example of land use in greater Chicago, the entire Skokie Valley Trail corridor is a rail-with-trail, paralleled by double tracks that sit about 40 feet to the west of the trail surface. The well-maintained asphalt path offers a nice, smooth experience for a multitude of uses. In addition, the trail shares right-of-way with a major electricity service company, and you will see high-voltage electrical wires overhead.
