? Don't camp on the Great Wall, as it is dangerous in inclement weather, and carrying lots of extra weight will dampen your hiking experience. ? Don't wear open-toed shoes to hike the Great Wall, even in hot summer. ? Don't go alone to the wild Great Wall. Travel with friends, and find a professional guide to facilitate access and prevent getting lost. ? Don't take photos from unsafe positions. First get a secure footing, and don't move about if you're standing near loose rocks/bricks. ? Don't climb on the windows of watchtowers, especially unrestored ones that might collapse.
