Confirmed from Six Mile Run 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.

State park with well-maintained trails for hiking, mountain biking, and exploring abandoned houses.

well-maintained 4 mentions

“We walked the Red trail June 5 - very well maintained and mostly shaded.”

We walked the Red trail June 5 - very well maintained and mostly shaded. This is a popular bike trail, so be aware that you may need to step aside to share the trail. There is quite a lot of poison ivy lining both sides of the trail so consider wearing pants.

Great trails. Lots of green trees at this time. Quite and very nature like. Also a great bike trail as well

★★★★★ — Cleveland , Apr 2022

there are alot of trails in this park. all the ones I have been on are good for walking or bikes. there are abandon houses along these trails which can be fun to explore. all trails have parts that have roots across the trails and going uphill or downhill.

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.
