New Hampshire, US
The Cheshire Rail Trail stretches for 42 miles between NH-12 near Bookseller Road and the New Hampshire–Massachusetts state line at NH-12. In Keene, the trail includes a beautiful stone arch bridge over the Ashuelot River. The trail takes a detour through Keene and then returns to the abandoned rail path on either side of downtown. The trail is used by hikers, mountain bikers (road bikes would have a tough time), snowmobilers, and equestrians.
