Tackling Hall Ranch up Lower Bitterbrush aka "The Rock Garden" bumps this intermediate/advanced area into solid double black. Lower Bitterbrush is only 2 miles long but it feel farther with the elevation gain, advanced technical rock features, and climbing steepness.

Start at the Bitterbrush parking lot and head up the trail. It starts out nice enough with a winding dirt track but soon the rocks come. They start out small, but get bigger and gnarlier as the trail goes on. Much of the challenge is finding the power to move through several big features back to back. The most technical section is only about a mile long, then it mellows out to the intersection with Antelope. Take a left on Upper Bitterbrush and climb to the Nelson loop. The preferred direction on Nelson is clockwise for a steeper/quicker climb and a longer, flowier descent. Come back down Upper Bitterbrush, then make a right to hit Lower Bitterbrush. Now you have a chunky, technical downhill trail you worked darn hard for so make it count

This trail feels right between Nelson Loop and Antelope in terms of tech/rockiness. It's fairly flowly in parts, but also fairly techy/rocky in parts. This makes sense because it's right in the middle of both trails! It's a somewhat exposed trail so bring sunscreen and water. Although rare, keep an eye out for snakes as well. I saw one a few weeks ago on this trail. Check out my video on Youtube if you want to see video of the uphill and downhill! youtu.be/aVmrf4V97oc?t=642

Trail Nelson Loop
I agree with the others. This is a very flowy trail with fast downhills. Speeds above 20 mph are easily possible! This is a great section for beginners because of the lack of rocks. The climb is very steep in a few parts so expect beginners and some intermediate riders to walk their bikes in a few sections. Check out my youtube video if you want to see the full trail! It will skip automatically to the start of Nelson Loop: youtu.be/aVmrf4V97oc?t=355

Trail Nelson Loop
Excellent trail for the beginner to intermediate rider. Mostly easy climbing and great descent. Heads up: BoCo had all traffic going directional Clockwise on the day I rode, so keep your eyes peeled for a sign directing traffic at the top of Upper Bitterbrush where the park bench is.

Makes for a great technical climb, with steep but grippy sandstone ledges.

As a descent, the main line is blue-black. But there's many optional lines to increase the challenge.
