This trail is in Clayton Park and provides an easy walk through rolling woodlands. It would make a great trail run an a fast mountain bike ride. A highlight for this hike was spotting a great horned owl roosting in a white pine tree next to the trail! (p.s. I should have read the other reviews more carefully, as stated the directions bring you to a NJ Forest Service facility, get directions directly to Clayton Park instead).

Moderate hills, roots, beautiful beech forest. Caution: Bow hunting in fall except Sundays

A great trail for running because of the nice dirt trails and because it isn't particularly rocky. Well marked even though the trails are really well used and obvious. For a circuit trail run, this park is ideal!
