Confirmed from Mill Brook Preserve'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.

What runners say about Mill Brook Preserve

Pulled from public reviews of this trail (21 of them) — the things people bring up again and again, in their own words. Nothing here is written by us.

This cute park is one of the many hidden gems from PRLT in the greater Portland area. It was fun to follow the brook and see the fish. It's a great place to bring young kids. My only reason for 4 stars is that the particular trailhead we used had VERY limited parking and likely would only fit one vehicle.

★★★★☆ — Susie , Jul 2023

Busy, but quiet. A nice piece of wilderness in the middle of Westbrook. Trails are very well maintained. Great family times

★★★★★ — Matt , May 2020

Nice trails and good hiking. The maps aren't the best though. Ended up 1.5 miles from where I was shooting for.

★★★★☆ — Roderick , Aug 2019

Nice long walk / hike through the woods and powerlines and along the brook. Good workout on the leg muscles. Seen brook trout , frogs , chipmunks, snakes , ducks ,.

★★★★★ — Karen , May 2020

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.
