Around Delaware’s beautiful Blue Rock cliff, formerly quarried and now home to the state’s only natural rock-climbing wall, natural resources like mature woodlands and the Brandywine River meet a rich industrial and cultural history at Alapocas Run State Park.

The Blue Ball Barn, now a popular event space named for the Blue Ball Tavern that once served travelers in the area, was built in the 1900s as a dairy barn that supported A.I. DuPont’s Nemours estate. It now houses the Delaware Folk Art Collection and tells the park’s history in story form.

Pawpaw trees, North America’s largest native fruit-bearing tree, grows in the forest understory. Delaware’s only venomous snake, the non-aggressive Northern Copperhead, occurs here. A Storybook Trail winds around the Can-do Playground, designed to be accessible to every child. Alapocas Run is also home to the Northern Delaware Greenway Trail, a National Recreation Trail.
