tourne is a good place to go. i recomend going early. i also like sterling forest. +1 on cunningham park, i just wish it was up and running back in the day, as I'm a queens guy. sprain is good too, not far, ringwood can be beginner friendly as there's an easy 6 mile loop from lot c, although i take tarmac back from shepherd's lake. other places like saddle river park have a little bit of trailage. essex county rail trail, and so on and so forth. if you don't mind going up to ny, stewart is good, but make sure it's dried out
