By far the best way to ride Hall Ranch. This ride is best started by parking in the town of Lyons either at Redstone Cyclery or Oskar Blues. Ride northwest out of town and turn left onto Apple Valley road. After a 15 minute road ride you'll end up at the start of the Antelope trail. Take Antelope up and keep right at the fork to continue onto Upper Bitterbrush. Continue to climb Upper Bitterbrush until you reach Nelson loop. Riding Nelson clockwise provides the best descent. After finishing the loop head back the way you came and be sure to turn right to hit Lower Bitterbrush. Gear up for a gnarly, technical, but surprisingly flowy descent through Lower Bitterbrush. After popping out at the Lower Bitterbrush trailhead head left down highway 7 and back into town.

Lower Bitterbrush needs to be downhill only. Upper Bitterbush cannot be enjoyed during times when there is more than light trail traffic. Nelson Loop is good because 99% of people ride it the correct direction.
