Small park with easy trails featuring Lake McCormack in the center.

4.6 miles. Surface is gravel or dirt. Little elevation change. No dogs.

Our two cents:

More of a casual hike destination but a good central Jersey option to get some miles in.

Maggie’s trail is probably the most interesting, as it extends into the lake on a skinny strip of land.

Nice nature center with many displays. Train noise in much of the park.

Updated: 4/2020: Page refreshed, not re-hiked. 11/2019 – Noticed this now allows bow hunting certain days; closes entirely for firearm. Check park site for latest details.  No-hunting park year-round. 


Print ahead or stop by the visitor center. Did not notice any at the trail kiosk. Most intersections have signs denoting color and direction.

Go around to the opposite side of Audubon building to pick up the trail at the tree line.

The trail follows the water edge but there are a few casual trails and some end in flooded sections.

You may pass a metal chime (…of course you’ll need to ding it a few times).
