Most people have heard of the great wall, several will have visited it, but only few have experienced "a more authentic" tour on the Great Wall. Together with some friends of mine I took part in an organized tour on the great wall in 2010 and can highly recommend such an activity. After a 2-3 Hour drive from Beijing you are possible to visit some of the very authentic parts of the great Wall (e.g. Simatai section) . Our tour included a 4 hour walk on the great wall and transportation from the finish point. to a restaurant and abck to beijing. It was an awesome experience walking on and along the great wall which was only renovated partly, meaning that it was very authentic and sometimes required more effort to get along. But we really liked the active hike! Walking on the great wall provideds the possibility for astonishing views on the landscape and taking impressive pictures of the great wall and the nature which is surrounding it! 100% recommended ot other travellers!
