Confirmed from Walnut Park'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.

Relaxed park featuring a playground, swings and a basketball court.

What runners say about Walnut Park

Pulled from public reviews of this trail (69 of them) — the things people bring up again and again, in their own words. Nothing here is written by us.

well-maintained 7 mentions

“The surrounding area is clean and in a very nice neighborhood.”

Great for walks at night and nice big open field for sports, also has a nice little basketball ball court, and dog friendly

★★★★★ — Freddy , Jan 2020

Great concrete walkway surrounding the rolling grass hills and trees. Two separate play structures (one for the littles) both with swings, double-rim basketball hoop with chain net, and lots of grassy space for catch. No bathroom facilities noted, but I may have missed them.

★★★★☆ — B. , Jul 2022

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.
