Corona Canyon is a short climb through a ravine. To reach the trail you’ll first drive a section of the Quebradas Backcountry Byway and half of the Hidden Valley Loop. There is a named obstacle “The Gatekeeper” that is a steep, loose, off-camber section that is the most difficult obstacle. This is for experienced drivers and you’ll need a vehicle with a lift, large tires, and at least one locker. Flash flooding is common in the area and rattlesnakes have also been seen so be cautious.
