Deer Path Trail (White Blazes) is the longest trail in Deer Park at 6.6 miles and follows the perimeter of the park. To the north, you can travel unmarked trails to the route 80 scenic overlook. On the West side between Birch Trail
and Barberry Trail
you can travel down to the Allamuchy Pond Trail that travels North around Allamuchy Pond. On the East side of the park there are two connectors for accessing adjacent Stephens
The trail has some technical sections, mostly on the Northeastern side of the park, but it's still reasonably tame by Allamuchy North standards.
