Prospertown Lake is located near Jackson, NJ and is good for all skill levels. The trail is primarily used for canoeing and is accessible from April until October.
Okay, so I'm a little embarrassed by the fact that I went to HIKE Prospertown Lake (given the apparent hiking trails on the map to your right). Surprise... those trails are all private property owned by Six Flags Great Adventure with dozens of No Trespassing signs. I did explore the north side of the lake with a little bushwhacking expedition. Very pretty lake. NO HIKING TRAILS that I could findh. I would like to go back with a canoe. I posted a couple pics of the lake. Enjoy!
