This trail system is made up of nearly 6 miles of tight, twisty, all-dirt singletrack in 3 separate loops, with a 4th loop in the works.(Fourth trail is complete)
Modest elevation gain, thick forest, and smooth hardpack make for rides which will satisfy every rider from beginner to advanced. The trails were designed in such a way that they would be a place not only for beginners to try out mountain biking, but also to allow more advanced riders an opportunity to test their bike handling skills by riding the narrow trails at a more rapid pace.
