A fast, flowing downhill trail with no technical features other than some swooping berms interspersed with some bumps. The upper portion may be beyond the liking of absolute beginners. There is a tie-in to the lower portion which may be more appropriate for these riders.

Access Info

There is a tie-in connection from Lower Mossy Maple to the lower portion of this trail for sessioning some easier flow rides (making a 3/4 mile circuit). There is also a connection across Lower Mossy Maple trail from the end of Yew Haw and shortly before the extension to Lower Mossy Maple branches off to the left.
