Confirmed from Oat Nuts Park Trail'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.

★★★★★ — Shaun , Feb 2024

Great trail the leads down to The Presumpscott River Falls at the former site of Smelt Hill Dam. Well maintained by the good folks at Portland Trails, I'd rate it as an easy to moderate hiking trail!

★★★★★ — Steven , Dec 2017

My go-to spot for a quick, woodsy dog walk as well as the occasional longer hike down to the Presumpscot River. Lots of trails connected to this one.

★★★★★ — Larry , Feb 2022

Part of the Portland trail system. Lovely well-maintained trails. Easy hiking, no hills. Walkers, joggers, cyclists and dogs on leash welcomed.

Trail conditions & character

What this trail is actually like underfoot and overhead, taken from its own listing and from reviews. Each one links to every other trail with the same character. Busy or quiet is reported as a plain fact, not a plus or a minus — a runner heading out alone at dawn often wants company on the path, and someone running intervals wants an empty one.
