Located south of the dunes, on the cliffside edge of Sand Mountain, Plan B is an adrenaline rush from start to finish with countless climbs, drops, cracks, off-camber leans, and optical illusions next to a towering cliff face. This trail travels through tight canyons with gravity-defying walls. It traverses white-knuckle shelves next to sheer drop-offs as you try to keep your focus on the trail and off the spectacular views of the Arizona Strip and Warner Valley. If you are looking for a trail to make you pucker and conquer obstacles that leave you certain the vehicle is on the edge of rolling, this is the trail you need to head to.
