The Nashua River Rail Trail is a former railroad right of way that travels 11 miles through the towns of Ayer, Groton, Pepperell and Dunstable. The trail offers a 10-foot wide paved surface for the entire length, and a five-foot wide gravel equestrian path for seven miles of the trail from Groton Center to the New Hampshire border in Dunstable. The entire trail is open to pedestrians, bicyclists, inline skaters, wheelchairs, and cross-country skiers. The Nashua River Rail Trail travels along a varied landscape, offers numerous scenic overlooks, opportunities to see wildlife and has several resting stops. The trail is particularly attractive during fall foliage season. The Ayer trailhead offers access to commuter rail service between Boston and Fitchburg.
