A short but scenic trail along Nordic trail corridor with well-defined summer singletrack”
— Phil Hess
Upper South Fork trail ends on the Middle fork access road, where you can cross and take a narrow trail down Middle Fork, aka poop shoot which alternates between singletrack and open nordic trail, with views of the creek and gentle grade all the way.
Watch for a left turn, across the creek about half way down, and near the end take a steep short climb and right turn to end on Andesite Road, just above Town Center.
This can also be used as an out and back climb, or continue on to connect with other Big Sky Resort trails.
