Confirmed from Old St. Louis Natural Area'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 Old St. Louis Natural Area

Pulled from public reviews of this trail (35 of them) — the things people bring up again and again, in their own words. Nothing here is written by us.

🌾 quiet & peaceful 3 mentions

“Serene trail, some fishing potential, lots of wildlife and greenery to admire on this short stretch.”

Serene trail, some fishing potential, lots of wildlife and greenery to admire on this short stretch. They have a neat little sitting bench along the path, but it’s best to keep moving if you’re visiting during mosquito hours. Absolutely beautiful though; I recommend making a stop here when you have free time!

★★★★★ — Khy , Nov 2023

Great hike, fishing, tadpoles, toads, snakes, turtles etc. Not much shade.

★★★★☆ — David , Aug 2023

Pretty neat little, quick hike that ends at the river.... if you weren't paying attention for it, you would miss it... I did for years... only downside is there are quite a few landmines left by dogs with careless owners, so mind your step...

★★★★★ — Ian , Jan 2019

Natural area. Soft surface walking trails, out and back. Level trail. Parking lot. Handicap parking & accessible. Wildlife area. Dogs welcome on leash. Quiet & not busy. Peaceful

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.
