An epic singletrack, climbs from approx 8400 feet to over 11,000 in about 9 miles. However, the climbs are mostly gradual, and the beginner mountain biker with some moderate skill can ride at least the lower few miles without a problem. Several stream crossings. You can also shuttle this trail for a sweet 30 minute flying downhill. Check out www.southforktrails.com for a video.
From South Fork travel 18 miles North on Hwy 149. Turn left on Deep Creek road, travel 2 miles to the well marked trailhead on your left.
