Wharton State Forest is in South Jersey. It is part of the Jersey Pine Barrens. The Pines covers large parts of Burlington, Ocean, Atlantic and Cumberland Counties. It is part of Pine Barrens National Reserve. There are no trout as far as I know. It is not what people think of when they think of New Jersey. There are no oil refineries.
The terrain is very sandy with rolling hills. It is covered in pines of several species. The fish are mostly warm water species. Small streams and ponds are located in many places and the streams flow dark with tannic waters. It has a very high water table with water just a few feet below the surface.
It is a great place for hiking, canoeing, biking or kayaking. It has a fascinating history going back to the early 1700's. It is the birthplace of the Jersey Devil, the 13th son of Mother Leeds (don't get stuck in Leeds Point after midnight on a moonless night).
It produced iron for the revolutionary forces during the war of independence. It supplied masts for pirate ships and was the home to bandits.
A great hike in Wharton is a hike to the Carranza Memorial. If you are interested Wiki Jersey Devil or Ong's hat. Bring your kids for a great day or weekend. There are lots of campsites in the area and some nice ponds and lakes for swimming and wading.
