Confirmed from Discovery Park at the River Line'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.

Update: I finally got back out to Discovery to see all the parts I didn't ctlatch the 1st time. I did not expect the views even in a relatively small place. The varied landscapes make it seem much bigger than what it is. Original Post: I was able to explore several different trails my first time here.

This is a FANTASTIC park. We take our dog here all the time. Loop around the bottom is around 1.1 miles or so, and borders the Chattahoochee. It's partially paved and partially wooded / dirt, so just be mindful of that if it's been raining.

★★★★★ — Rob , Apr 2025

Thank you for your SPLOST funds Cobb County! This new park is still under construction but will add a nice place to take dogs, hike, walk, find solitude, and see unique views of the Chattahoochee river! There will be a nice wetlands boardwalk bridge to gain nice walking views along the river.

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.
