Historic bridges, tunnels and small towns are dotted along America's 31,000-mile trail system created from a web of rail lines.
The Rails-to-Trails Conservancy created the national network and these now-vibrant trails are used by walkers and cyclists easily accessible to children, adults, the handicapped and senior citizens.
Here are 11 courses that will wow you with their charm, beauty, length and history.
