Badaling Great Wall is the site of the most visited section of the Great Wall of China, about 70 kilometers northwest of Beijing urban area. The Great Wall in Badaling has been carefully restored, and in 1957 it was the first section of the Great Wall to open officially to tourists. The immediate area has seen some useful development, including hotels, restaurants and a cable car. The scenery at Badaling is great in every season. There are sunlit and enchanting scenes in spring and summer, when the valleys covered with greenery. When the rain comes, the view looks vast and hazy. The sky in autumn is high with an unsoiled stratosphere, while the maple forests are golden and red in colour. White snow covers the whole scene in winter. Over 100 million visitors have already climbed Badaling Great Wall. See here a video :  "Hiking on the Great Wall"
