Confirmed from Half-Acre 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.

★★★★☆ — Jugs , Apr 2022

It was our first time there. We went there with 2 if our youngest grandkids and they had a blast. They enjoyed the swings and slides and the jungle gym. There's also a nice section for dogs that is totally fenced in with training activities for them.

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.
