Killer B Trail
Descent from Bar B to old highway 191

The Killer B is a very short but insanely steep downhill route in the Brand Trails. It extends from the south end of the Bar B loop to old highway 191. Killer B itself is only 0.8 miles in length, but the minimum ride that will get you on this trail is 8.4 miles.

You'll descend 650 feet, an average 20% rate of drop. Only very skilled riders should go on this trail! A couple of sandstone slabs are so steep, you can't stand up in bike shoes -- you gotta ride!

At 0.6 miles from the top, the trail forks. The older trail to the left descends a series of steps. It's hike-a-bike. To the right, you'll descend through some switchbacks on the newer 2012 trail.

Getting there:

When you see the Gemini Bridges parking area, look for a gravel road on the opposite side (east, away from the cliffs). Turn onto the gravel road and immediately go right, then right again into the parking area. GPS N 38° 39.38' W 109° 40.66'. The trail starts by riding the gravel road either north or south. Our ride description assumes you'll ride south out of the parking lot, counterclockwise on the Bar M.
