Great Wall North of Beijing
This is a section of the Great Wall north of Beijing, known as Mutianyu. There are three stretches of the Great Wall close to Beijing that most tourists visit - Badaling, Mutianyu, and Sumatai. Of these, Badaling is the closest to Beijing and is toured by most people. Sumatai the farthest (80 km?) and sees few people. Mutianyu is somewhere in the middle both in terms of location and popularity. Visitors can get up to the Great Wall by cable car from the foot of the mountain. Actually, it is relatively easy to climb up to the wall. One can decides how far he wants to go in either direction once he's on the wall.
