For trail lovers around the country, these two Idaho rail-trails hardly need an introduction: the 73-mile Trail of the Coeur d'Alenes and the 15-mile Route of the Hiawatha.

The Great Allegheny Passage, the country's longest multi-purpose trail and the site of the 2007 Greenway Sojourn, and also the first inductee to Rails-to-Trails Conservancy's Rail-Trail Hall of Fame.
