The terrain is very rocky, and can be treacherous when wet. There are 15 or 16 log crossings (some of them are pretty big), a couple of stream crossings, some rocky climbs, and a couple of fast, scetchy descents. Overall, this is a very cool trail to go out and have fun on. Oh yeah, there's even a cool north shore type bidge up and over a big log.
How to get there:
Rt 206 N from Newton, NJ to park entrance(about 20 min. from Newton) Drive past Ranger Station and continue straight untill road comets to a "T", turn left and enter parking area, this is the Kittle Field parking lot. Ride out of lot to the left on road and go up hill to Stony Lake, take the Swenson trail. Keep left at all trail intersections and you will make a loop. There are many more trails if you have all day>
The State Rangers are very tolerant of mountain bikers and many of them ride themselves, so be nice!
