Distance: 20 mi
Shape: Not reported
Shade: Not reported
Access: Open 24 hours

Confirmed from Coal Creek Trail Flagg Park Trailhead'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.

🏞️ beautiful scenery 3 mentions

“Beautiful scenery, lots of wildlife, great place to walk my dog”

Very pretty area once you get away from the road! Very well-maintained, relatively flat, gravel trail!

★★★★★ — Brian , Mar 2025

Lovely trail for exploring with little kids or longer bike rides and runs. Flat.

★★★★★ — Lauren , Apr 2018

4-star toilets (tp, sanitizer, seats, doors)! Good bike stop. Excellent access to Coal Creek biking trail going all the way from superior to Erie. No running water, if you hike/bike into the park there are some pleasant picnic tables in the shade. Might be buggy.

★★★★☆ — Connie , Jun 2026

Easy access to Coal Creek and Rock Creek trails. There's a port-a-potty if you really need. Otherwise this is just a great parking spot with access to tons of trails around Lafayette/Erie.

★★★★★ — Scott , Apr 2024

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.
