Some things are best left to their natural state. That’s pretty much the case with Herrontown Woods Arboretum. This 142 acre woods, which once belonged to one of Princeton University’s most prestigious math profs, is thick with woods and copses of trees. More than 30 species of trees, shrubs and wildflowers are scattered along the trails that wind through the Arboretum.

Mostly you’ll see oak, American beech, swamp maple and pine trees but there are other green-growies here. And if you aren’t sure what you are looking at, there are markers throughout Herrontown Woods that give you a few details about the various species.

As for birds, warblers and deep-forest birds are all over the place. Just bring your binoculars and look up. You are bound to see something.

There are roughly two miles of trails that will give you a good, but not exhausting, workout. The inclines are gradual and there is nothing too steep so it is good for beginner and intermediate hikers. Just be aware that there aren’t any other facilities -- no restrooms, picnic facilities or food stands. But with acre after acre of leafy, mature trees who needs snack stands.
