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.

 Awesome ride. I actually ride up Bitterbrush and down Antelope, then back to Lyons. Better on 58 yo bones. Be sure to ride the loop at the top clockwise.

 2 way traffic is strangling this trail. Great features, flow, and length. Needs better trail / user management in order to be a great trail.

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.

 Welcome to riding on the Front Range. Directional an/or bike only trails are a pipe dream. I agree with your points (aside from Lower Bitterbrush as that's a fun trail to climb and test your technical skills and physique) that trail use often kills the flow on this trail and makes blind flat corners even more dangerous but for some reason land managers just don't seem to think directional trails are a good thing even with the tons of new trail users the Front Range and all of Colorado are seeing.

 Rad trails but this area could benefit from an expanded trail network, it is far too busy (even a Tuesday in October) to really enjoy these trails as they’re designed.

 Bitterbrush 100% dry and fun. Lollipop loop a little wet at times but 95% dry and clean. Have fun!
