The Yanmenguan Pass is an absolute masterpiece of ancient defensive architecture and one of those places that leaves a colossal impression in person. Standing on the walls wedged between the rugged, steep slopes of the Hengshan Mountains, you immediately feel the immense weight of history. For centuries, this was the strategic and incredibly bloody border between imperial China and the nomadic tribes from the north.What captivates about Yanmenguan is the incredible combination of raw nature and monumental architecture. The fortifications, massive gates, and watchtowers look as if they literally grew right out of the rocks. Hiking along these sections of the Great Wall delivers a huge rush of adrenaline—the climbs can be steep, but the view of the wild, empty mountain ranges completely makes up for it. It lacks the heavy crowds and commercialism found near Beijing, allowing you to absorb the raw, almost cinematic atmosphere in peace.
