The pacific northwest has nothing on this place. Painstakingly created network of bridges, tree crossings, seesaws, etc. Most of it is for experts, and you had better be, otherwise get off and walk. Absolute insanity in some spots!! Probably one of the most difficult series of singletracks in the Northeast. Definitely a triple black diamond rating in many of the secluded singletrack areas. One downside is that there are a number of deadends, but when you get to know the layout, these can be avaoided.
Take exit 3 from Rte. 93N; right from the exit; left at the lights. Continue through 2 sets of lights, crossing Rte. 28, passing a US Gas station. Just past the Elks club on the left, and the town yard on the right, there is a sign and parking area for the Salem Town Forest. Park there, ride over the bridge and be prepared.
