Maps of the creek (1934/2010/2021) Castaway Island and Timbuctoo. Beacon Hill Trail at Long Bridge County Park is top notch. Hike along creek bluffs, weave among old sand mines, expansive Northern views into the State of NJ Rancocas Natural Area and Rancocas Nature Center Bluffs. Burlington County hits a solid home run for access with the Beacon Hill Trail.
