Manasquan Reservoir Perimeter Trail is a 5 mile loop trail located near Colts Neck, NJ and is rated as moderate. The trail is primarily used for hiking and is accessible year-round.
I really enjoyed this trail. We parked and walked the complete trail around it was about 5 miles. Got beautiful pictures
Loop is flat. I would say it's an easy trail, not moderate. Always many people on the trail, and the manasquan reservoir is pretty, although a good portion of the trail is right on the highway.
