The southeastern end of this trail is accessed from Pennington Borough’s Kunkle Park, which has parking for a dozen or more cars. The northwestern end of the trail is accessed from North Main Street, where a couple of cars can pull off the road at the gap in the guardrail just east of the railroad overpass.

Dogs permitted on leash. Please clean up after your dog.

This trail can be very wet in sections; users are advised to wear boots except during dry conditions.

Kunkle Park, which is next to the southeastern end of this trail, has a picnic area with tables and children’s play equipment.

This trail arcs around the northeastern edge of Pennington Borough. This is not a loop trail, but walkers can connect the two ends of the trail route into a loop by walking the pleasant residential streets of the Borough of Pennington. The trail traverses a property owned by the D&R Greenway, a property covered by a conservation easement held by the Greenway, and a property owned by the State’s Division of Fish and Wildlife.

The main trail traverses a mature hardwood forest in the floodplain of the Stony Brook and the southern shore of Baldwin Lake. A portion is along the edge of an agricultural field. Branch trails connect the trail to a residential development.

The lands through which this trail passes are valuable wildlife habitat. Great Blue herons and Wood ducks can be seen in the Stony Brook. Neotropical song birds use it to nest in spring or as a stopping place on their Spring and Fall migrations.

There are some remarkably large trees, particularly Pin oaks, here and there is a string of vernal pools along the base of an embankment that are valuable for frog and salamander life.
