Our small group took a bus to visit the Great Wall directly after visiting Beijing. We recommend taking along walking sticks should you plan on following one or the other piece of wall as they are at times extremely steep. In the turret I walked up to they were selling cheap coins and certificates to show that you have been on the Wall.
My husband was stopped by an energetic 12-year-old who spoke good English, whether she could ask him questions. She then translated them into Chinese to the rest of the passers-by. Hubby quite enjoyed his “stardom”, but needless to say, all the Chinese people we met were very pleasant, cheerful, curious. However, not everybody speaks English in China as we found out later on!
At the bottom of the hill you will of course find flower beds, toilets, souvenir shops and cafés for the tourists. Some of the souvenir items were absolutely stunning and some also rather large, like life-sized warriors and horses.
Unfortunately, there are only a few sections left of the Great Wall. It is certainly worth climbing on, the view is spectacular.
