You'll pedal past the rich biodiversity of the Occoquan Bay National Wildlife Refuge and Mason Neck State Park, where you might spot bald eagles and Great Blue Herons. The route features mostly well-paved surfaces, but a few unpaved sections mean a hybrid or gravel bike could enhance your comfort on this journey through natural vistas.
