Confirmed from Four Mills Nature Reserve'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.

“Nice easy trails, relatively flat, a few cool bridges over along the way too”

First time here and I must say it's been a good experience. There are trails, bridges and stepping stones that are very well maintained. Also, we saw some wooden benches scattered throughout the area. It was nice finding young trees carefully wrapped in nets so they grow protected from the always grazing deers.

Nice trail, lots of quoet walking and clearly marked spaces Only problem? There's a spot where you have to cross the creek on a series of stones. The middle stone had gone under when I went there. Made it more treacherous than it should have been.

★★★★☆ — Robert , Nov 2021

Well kept trails. A nice local place to go hiking if I don't have time to drive anywhere. There is some road noise, but the nature sounds nearly drown it out.

★★★★☆ — Lin , Aug 2020

Awesome trial to walk during spring time, tons of wild flowers everywhere. Kids love the concrete block passage to cross the creek, however one of the stepping block is not in place so we decided not to cross but to walk back the way we came. Our little pup loved the walk, most people we saw there were with their dogs.

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.
