The Wave, Coyote Buttes, Arizona
The Wave is a dramatic sandstone formation in the desert of Coyote Buttes, in Vermilion Cliffs National Monument. It sits just inside Arizona, but you must hike 10km (6mi) return from Utah, making your way by landmarks and/or GPS. Only 20 groups are allowed to hike there each day, and permits are available in advance by lottery. I was fortunate to get a permit. HDR
