Heron Run is a .7 mile easy hiking trail that follows the western side of Douthat Lake. It is accessible from the Discovery Center, the Blue Suck Falls, Middle Hollow, and Backway Hollow trails. Near the discovery center the trail crosses a small bridge, traverses the spillway via concrete steps, and passes through wooded areas along the lake. The trail is fairly flat in most places with the exception of the spillway stairs and is an excellent trail for families with children.
