Lower Forge & Mullica River Camps is a 13.5 mile lightly trafficked out and back trail located near Vincentown, New Jersey that features a river and is rated as moderate. The trail is primarily used for hiking, trail running, and camping and is accessible year-round.
I used this trail to spend an overnighter at the Lower Forge Campground. From a hiking perspective, it's an easy trail. You're in the Pine Barrens so it's a sandy trail, and apart from the river there's not much variety to the scenery. And as you approach the area of Quaker Bridge Road, you'll see and hear many people enjoying offroading in their trucks, ATVs and bikes.
The campground was a disappointment. The sites are basically right next to each other, so you don't get any privacy. And there was not much dead wood to be found (if you plan on doing a campfire).
