What do you mean? Badaling is almost deserted. Look at the two Badaling photos in this thread (posts
18 and
42).
Ha ha.
I had to be at Badaling very late in the day, on a week day, to get those photos and still I was lucky. Badaling is terribly crowded for sure, but it's still interesting and impressive. The views are hard to beat, especially on a clear day. Just don't go on a weekend or a holiday! Most people walk (or take cable cars) up the east side, so if you go west at the entrance, it's much better, too. Qinglongqiao, immediately to the east of Badaling, is even more impressive and has not been rebuilt.
