425 Wedgewood Rd., Newark, Delaware
You can look into Pennsylvania and Maryland from this pleasant park nestled in the northwestern corner of Delaware, where the three states come together. Their meeting point, known as The Wedge, was once popular with bandits, who could quickly escape the law of one state by crossing the boundary into another. The park has a spacious 3,384 acres, rising to about 300 feet—which is high for Delaware—and offering long views of the surrounding countryside.
Hikers can explore valleys and impressive rock outcrops on 37 miles of trails. The Millstone Trail shows where grindstones were once quarried from the exposed boulders. In the spring fishermen like to cast for trout from the banks of a creek that runs alongside the park. And in winter the slopes provide fine tobogganing.
Open year-round. Admission charged.
