Confirmed from Grand Lake St. Marys State 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.

“The lake was beautiful and the park pretty much surrounds the lake with hiking and biking trails a nice large campground that also offers cabin rentals.”

A very nice State park located in west central ohio. The park is about 600 acres. You can hike, fish, boat and camp. There are also three lighthouses around the lake. The towns of Celina and St. Mary's are also worth a visit. The person manning the park visitor center was very helpful in planning our visit

Park is one of our favorites. It is a nice clean park. Clean bathrooms and shower house and has enclosed dog run which was nice for our dogs. Sites are a good size. Nice pool, splash pad, giant size checkers, swings.

★★★★★ — Claudia , Sep 2021

What a great state park with so much to offer. The lake was beautiful and the park pretty much surrounds the lake with hiking and biking trails a nice large campground that also offers cabin rentals. There is a marina and sailing club and picnic facilities through out.

★★★★★ — Ray , Oct 2023

This is a large lake with many different areas and parks.This is a review of the state park on the northeastern part of the lake. This area has a beach,walking path, boat launch, playground, shelter houses and restrooms. There seems to be quite a few improvements being made. The area is clean and well maintained.

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.
