This area behind the Plainfield school features 10K of groomed XC trails in the winter, plus an abandoned alpine ski area, so this place has it going on all year around. Besides the XC trails there is a bunch of single track with quite a bit of vertical for a modest footprint so there are some very fine downhills. The primary easy access with ample parking is at the Plainfield School.
