Confirmed from Palm Island | Mile Square 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.

What runners say about Palm Island | Mile Square Park

Pulled from public reviews of this trail (229 of them) — the things people bring up again and again, in their own words. Nothing here is written by us.

Great place to take the family, go relax and enjoy the wildlife. If you like a little bit of fishing the lakes are stocked with catfish, and trout, of course depending on the season. Plenty of room for the kids to run around and just be kids The playgrounds are clean and they have really done great work.

★★★★★ — Jerry , Apr 2022

Great local parks for recreation and fun! The place is big with all kinds of facilities, with a lake and ducks, and of course, nice grass lands for playing and nice paved walking trails. I enjoyed it very much visiting there and spent hours there and having lots of fun.

★★★★★ — Raul , Jan 2023

Pretty big park. Tons of grassy areas. Only downside is that there's a lot of bird poop everywhere. Great for a run or walk. They have Sean boat rentals and bikes as well.

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.
