The Nassau Trail system is a quickly expanding system in High Bridge, New Jersey. The single track to the right of Nassau Road has about 5 miles of mostly flat, windy single track that consists of mostly smooth, however sometimes rocky and rooty singletrack. The northern part of the system has some log skinnies that can challenge advanced riders. To the left of Nassau Road, there are another 3 or 4 miles of single track that is flowy and windy with virtually no rocks or roots, expect for to the northern part of this side, with a couple of rock gardens. Overall, a good ride that can last up to 2 and a half hours.
Take the exit for 513 going north. Continue on 513 for about a mile, then turn right on Arch Street. Once the road ends, turn right onto Washington Avenue, and continue on Washington Avenue until Nassau Road on the right. Continue up the hill and the parking lot is on the right.
