Jiankou

Jiankou is a section of the Great Wall in Huairou featuring dramatic ridgelines and steep slopes. The structure runs along white limestone crests with several defensive towers positioned at strategic points along the route.

Construction of this wall section began in 1368 during the Ming Dynasty as part of broader frontier defenses. The structure was reinforced during restoration campaigns in the 16th century.

The name Jiankou means Arrow Nock, referring to the mountain formation that resembles a drawn bow ready to release. You can see this geological shape clearly as you walk along the ridges.

Access to this unrestored section involves several hours of hiking over steep terrain. Bring proper footwear and water as conditions can become difficult in wet weather or low visibility.

This section contains the Sky Stairs tower, built at an extreme vertical angle that makes it nearly impossible to climb safely. The dramatic slant creates a striking and unsettling sight for hikers passing by.
