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
