It is said that you are not yet a man until you have conquered the Great Wall. I don't know where it came from or who said it (come to think of it, maybe it came to me in a dream) but I absolutely had to visit this place when I was in China.
Packaged tours generally take you to the closest part of the wall in Balding. I'm told it contains more tourists than views. I wasn't going to to find out on my own. I, of course, opted to take in some of the more quaint (and original pieces of the wall) in Jinshanling. It was worth the extra effort. There may have been 50 people in the entire 10-12km stretch.
