Phase 1 is 22 miles of 3 connecting loops that are mostly excellent single track. Most of the Phase 1 trails are quite technical. The White River Bluff Loop is 4.5 miles. Portions of the trail are quite technical, but the views of the White River and North Sylamore Creek Valley are worth the effort. Bald Sc***py Loop is 7.3 miles beginner to intermediate trails through Ozark Forest. Sc***py Mountain Loop is 12 miles of steep Ozark Mountain terrain. Beginners can ride most, but may need to push up/down steep switchbacks. Phase 2 has recently added another 16 miles of trail.
