Jiankou Great Wall
Jiankou Great Wall, Located in the district of Huairou and 80 kilometres north-east of Beijing, is completely in its original state, dating from the Ming period (late 14th century). Exploring these more authentic fragments of the wall is a great experience, however, it could be dangerous, as a lot of steep steps are crumbling. Although Jiankou is seldon know by the tourists to Beijing, it is very famous in local hikers and photographers interesting in Great Wall.
Many people learn about the Jiankou from illustrated books about the Great Wall. One scene is known as "Ying Fei Dao Yang" (the eagles have to fly upwards over a high tower), so named because a watchtower was erected on the highest peak, and eagles/hawks often perched on it. Another one is "Heavenly Ladder" - a flight of steps ascending almost vertically. These steps are so narrow that only one person can climb up at a time. The massive and well preserved watchtower is the best spot for taking photos and watching the sunrise. At the foot of the wall a couple of quiet and peaceful villages lie in the valley.
