*not a biking one. That being said theoretically there's some tricky parts to it near me that you probably couldn't go up stone stairs on Wiccopee mtn to what did we call it as kids... flat rock, on any bike unless you were one of those parkour hopper bike people. Much of its not too bad though from my limited experience. The other outlet after wiccopee mtn at fahnestock I remember going down a washout that I don't think you could bike up but that may have been a shortcut.
