Brendan T. Byrne State Forest
“…hikers can follow the sandy trails and roads that crisscross the forest, sometimes passing near the remains of stone or brick structures or where large depressions indicate the location of what was once a bustling town. Pure, iron-rich streams flow through acres of swampy land covered with dense stands of Atlantic white cedar.” The park used to be called Lebanon State Forest.

Cranberry Trail 1.1 mile loop. The blog South Jersey Trails has some images of it.
The sandy, pine needle-covered trails to Pakim Pond and Mt. Misery appear to be quite easy, although maybe longer than you would want to complete. They are described in nj hiking.
