Confirmed from Nashua River Rail Trail - Smith St. Access' 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.

“Extensive, well maintained rail trail that's great for a family ride or stroll.”

We started here, rather than trail head in dowtown Ayer. Beautiful sights and sounds here toward Sheply Hill. Only problem streets are not marked and we past the Smith ST access to were we got on the rail trail. Ended up going past it and ending up at the end of trail in Ayer. ...

★★★★☆ — Debbie , Apr 2015

Awesome trail, well maintained. Some in shade, some in sun. Fairly level, easy to walk, run, bike & rollerblade.

★★★★★ — Howard , Sep 2019

This is just a place where the trail crosses the street. There's no parking there
