We found Astronaut Grove while exploring near Alum Creek Park North. There's a paved pathway that runs underneath the bridge that was busy with traffic, so it was both a nice easy way to get across, as well as more relaxing, as it travels alongside the creek. Astronaut Grove has some nice green space, benches, and trees. The centerpiece is a sculpture, Reach for the Stars, designed by Kenneth S. Foltz, and a series of stars at the base of trees and plants that are dedicated to the astronauts of the Challenger. It's a very nice memorial. There is a parking lot available. read more
