Jay Powell
October 12, 2025, Nashua River Rail Trail

Paved route through the woods, although best taken at a slow speed to both enjoy the scenery, and accommodate runners, joggers, walkers, and small kids just learning to ride. Save the road racing for out on the roads.

The Nashua River Rail Trail is a paved trail that was constructed on an old railbed. It is completely traffic free, so it is a great place for a relaxed walk.

This is the northern terminus of the Nashua River Trail. It runs from this point all the way to Ayer, Massachusetts. The trail passes through J. Harry State Forest and is tree lined for a majority of its trajectory.

One of the older trails in the state but a great one. Some lovely views of the river at various points

This old homestead is meant to function as a buffer for Baddacook Pond, the water supply for the nearby town of Groton. But it also opens up vistas over the water, so it's a really nice place to bike past.

This stretch of conservation land abuts the Nashua River Rail Trail. You're free to explore the land if you want to hop off your bike, but it's kept in such a natural state that you won't even find maintained trails on it.

From here all the way south to Ayer, this 12.5 miles trail follows the course of the Nashua River through J. Harry State Forest. Calm and tree-dimmed light make the way a real treat.
