This is "The” hill to prove your off-road skills. It is a very dangerous hill and suggested for only experienced riders in certain areas. If you do make it to the top, there can be some nasty surprises waiting for you on the other side. There have been more people air-lifted from this area than almost any other in the Ocotillo Wells Off-Road State Park. This miniature mountain range arose from the seabed floor and is composed with rock, sand, dirt, and trillions on trillions of tiny seashells and ancient aquatic life.
