This DeKalb County park near Decatur splits play by age: a three-level pirate-ship fort with tall slides for bigger kids and a smaller playground with palm-tree slides for younger ones. Covered picnic pavilions, a community garden and an adjacent 120-acre forest with hiking and biking trails extend the visit.
