This side of John Heinz National Wildlife Refuge tends to be quieter. There are some singletrack hiking trails and some packed gravel trails that are great on the bike. The I-95 Trail will take you northeast to the central loop of the park, or you can take the Fishing Point Trail out to the middle of Darby Creek.

This area, similar to the world-famous Stonehenge, consists of a several-acre meadow with a circular arrangement of massive boulders. While mostly used for bonfires by local college students, it also offers a unique perspective from this viewpoint.
