This bike trail, on a former railroad bed, is 20 miles long and divided into two sections. The two sections in Vermont are separated by a length of trail in New York State. The Vermont sections stretch between between Castleton and Poultney, and between West Pawlet and Rupert. The trail passes through pretty countryside and there are places along the trail to have a picnic, fish, and stop for refreshments at stores.
The trail is open to walkers, bicyclists and horseback riders, snowshoers, skiers and snowmobiles. Trail access for the northern section is at Castleton State College or along Main Street in Castleton and in Poultney village adjacent to the old train station on Depot Street. Trail access for the southern section is at West Pawlet village on Egg Street and at the connection of Route 153 and Hebron Road.

This path provides bicyclists with a new and exciting way to experience the beauty of Vermont. The trail (which is not continuous but contains stretches of up to 4.5 miles of uninterrupted paved path) takes bikers all over the city, through neighborhoods and commercial districts, to corn fields and the banks of beautiful Lake Champlain.

Standing in the former tracks of the Central Vermont Railway, the Missisquoi Valley Rail Trail continues an historic link between St. Albans, Sheldon, Enosburgh, East Berkshire, and Richford. Farm-to-village commerce and international trade flowed through the corridor along a plank road in the late 1800s. It continued by rail until a derailment permanently closed the route in 1984. The State of Vermont and local citizens began converting the corridor to a multi-use trail in the early 1990s. Many traces of the railroad “Milk Run” days still exist along the trail for you to discover, including train stations, rail sidings, and creamery foundations.
This 10-foot wide multi-use path is paved mostly with crushed limestone, with a relatively level grade. See website for access points.

A 3.5 mile multi-use pathway on a former railroad bed parallel to the West River. The Lower Section of the West River Trail begins in Brattleboro near the Marina restaurant and follows the West River to the old granite quarry in Dummerston. The trail is flat. It is popular with runners, bikers, and walkers. About one mile from the Marina trailhead is the Riverstone Preserve.
Roads around West Dummerston can be used in combination with the West River Trail for extended bicycle riding. From the Marina Trailhead, you can pedal out the West River Trail and then follow Rice Farm Road and Quarry Road to the West Dummerston Covered Bridge. There is a park-and-ride lot on the west side of the bridge, just off VT-30. The distance is 6 miles one way. - Lower Section Trail Map (PDF) - Upper Section Trail Map (PDF)

The East Branch Trail is a 5-mile backcountry pathway built on a former logging railroad bed.
