Clayton is a fun place to ride. Some fast descents (for souther new jersey) and some good climbs. The trails are in great shape and there are some really fun logs to climb. Kind of like a big BMX course.
How to get there:
Take Rt 537 West to 539 N. Make a right at the street directly across from the golf course. When that road ends make a left and then a quick right onto Emly's Hill Road. The parking lot is about 1/4 mi up on the left.
