Including the climb on the Bar M , there will be 500 vertical feet of climbing. The western half of the Bar B has some short sections of advanced-technical riding.
At the southern end of the Bar B loop, the Killer B downhill route branches off to the right. You'll climb over the ridge on doubletrack, then head back on smooth doubletrack that becomes a slickrock path along the edge of the bluff.
