HikerwithcaneThere are two other easy, short trails – the 1.5 mile Yellow Trail and 2.0 mile Blue trail.   You may need to step up to and down from boardwalks, but I was told by the attendant at the visitor’s center that they are in no way strenuous.

Brendan T. Byrne State Forest

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.

“Lake Absegami, a 67-acre lake created in the 1930’s, is the center of the Forest’s recreational activities and provides an area for swimming and a serene setting for boating and canoeing.”  The Forest has eight easy walking (non-ADA accessible) trails from 1 to 3.2 miles.  All trails start at the second parking lot at the beach.  A trail brochure is available at the office.  Map and description of trails.  Phone 609-296-1114.   Here is the Forest Website.
? A self-guided 0.5 mile trail through the 128 acre Absegami Natural Area passes through a pine/oak woods and a small Atlantic white cedar bog. It includes a wooden foot bridge with benches.  I have not found a description of just how easy (or not) this trail is.  Call to learn more.
