I believe it's a must to visit the great wall when you visit Beijing, it's one of the 7 wonders of the world. It was really nice to experience the steepness of the path ways. There will be a lot of question marks in your mind while you walk along it. One of the question that I had in mind was, how fit soldiers have to be to stay put on their guard or maneuver along the wall. However, the Badaling stretch is just too crowded for me, and the scenery aren't that nice, I think there are other stretches of the great wall which are much better. Here are some to share.
