Jiankou Great Wall is part of the Great Wall, located in the mountain ridge of Xizhazi Village, Huairou County. It is thought to be the most picturesque section of it. To enjoy the view of the real face of today’s remains of the Great Wall, you may visit this section. The main section of JianKou Great Wallis built along a mountain ridge with steep cliffs on each side.

Jiankou Great Wall was an important section of the wall during the Ming Dynasty (1368 - 1644). Owing to the need for renovation, the wall is regarded as one of the most dangerous sections of the Ming's wall. It connects to Mutianyu Great Wall in the east and joins Huanghuacheng Great Wall in the west. From east to north, the wall zigzags 9.3 miles from 'The Ox Horn Edge Wall' to 'The Nine-Eye Tower' via 'The Beijing Knot'. Compared with Mutianyu Great Wall, the mountain is higher and steeper, while compared withSimatai Great Wall, it is more winding and varied. It was built from the local material - dolomite. The large pieces of white rock make the wall striking to the eye at a distance.

There are many famous sections of Jiankou Great Wall, such as 'The Nine-Eye Tower', an important command post during the ancient wars. It has three layers, and there are nine holes which look like nine eyes on each side. 'The Beijing Knot' is the meeting point for three walls coming from different directions. 'The Sky Stair', is a precipitous stair whose angle of elevation is 70 to 80 degrees. It leads to 'The Eagle Flies Facing Upward', a watch tower built on the lofty peaks. It is so dangerous that even eagles have to fly facing upward to reach the top. 'Zhengbei Tower' is the right place to appreciate the beauty of the sunrise and the sunset.

A few small areas of this section have been seriously damaged. So, you have to be careful this time while climbing. Besides this, rainbow trout of this area enjoys a good name and you can have a good taste of it.
