Confirmed from Nashua River Rail Trail Ayer's own listing, the park or land manager's website, and runner reviews. Blank cells mean we could not verify that fact — we would rather say "not reported" than invent one. There is no Easy / Moderate / Hard rating on this page on purpose: a one-word difficulty score tells you nothing about whether a trail suits your run. Surface, distance, shade and hours do.
Scenic bike path and walking trail winding through ponds and wetlands.

Beautiful rail trail for biking and walking that goes through Ayer, Groton, Pepperell and Nashua. Some nice off-roads that you can take near the Nashua River as well.
Great day of riding with my sister from Connecticut! They've done a lot of work on this trail. As far as the frost heaves, still some to be fixed but all in all much better than last year! Thank you to those hard workers that take care of our trails!
12.5 miles from the Trailhead in Nashua, Through Pepperell, and Groton to Ayre. Beautiful trail along a section of what was the Worcester to Portland Maine freight and commuter line. The center of Pepperell looks where you'd expect to see Andy and Floyd sitting outside the Barber Shop.
You can park here for free if you are using the rail trail. There are outdoor spaces and covered spaces. The adjacent paved trail is in three sections, all connected. I park here to ride my bike to Groton by their library. I refer to this as the 'easy' ride.
