Take I-80 West and exit at the sign for the rest area before you get to the bridge over the Delaware River to Pennsylvania. Park in the second parking lot (just past the rest area). Walk to the northern end of the parking lot and enter the woods on the Appalachian Trail (double white blazes).


Chestnut oak forest and hemlock-mixed hardwood forest communities, and rare species habitat.


You can take a circular hike, known as the Dunnfield Creek Circular Hike. From the north end of the parking lot you follow the double white blazes of the Appalachian Trail. The trail parallels Dunnfield Creek with its boulders of different sizes.

You will be taking the blue trail off the Appalachian Trail. Then there is an intersection of the Blue with the Red Trail. If you follow the blue you will go up to the top of Mount Tammany (1,527 feet above sea level). Follow the red trail instead. This will take you to Dunnfield Creek which you will cross twice.

At the intersection with the Appalachian Trail again, take it west and then south back to starting point where the white and blue trail intersect.
