Mountain Biking Trail 40

  Add a review
#22 of 42 mountain bike trails in South Dakota
#6360 in the world

The trail srarts at the highest lake in the hills and leads mostly downhill with only the climb out of the lake basin.I always shuttle on this ride so I can be met either at the ghostown of Mystic-last few miles are a very fast fire road ride,or be picked up at many of the fine diners in Hill City-last 7 miles of long fast mountain road racing,wee! The trail is for experienced riders,and will challeng and excite any hardcore bike.
