Snake Way is the only access to the ancient city of Petra. Hidden in the mountains around, more than 1000 meters above sea level in the alpine canyon, it is difficult to find. This narrow road is as slender and winding as a snake, so it is called snake road. The narrowest part of the serpentine road can only pass through a camel. Looking up, it is a narrow gap. Walking into it, the sun can't shine, which is the magic of nature.
