Accessible by cable car (CNY 60 roundtrip) or foot, this section of the Great Wall has been restored and is one of the most heavily trafficked areas of the Wall. From here you can see the wall weaving, rising, and falling over the contours of the lush terrain, zigzagging from peak to peak. This section of the wall is 7.8m (26ft) high and 6.5m (21ft) wide at its base, narrowing to 5.8m (19ft) on the ramparts. Along the walk are embrasures for archers and gutters with gargoyles to drain rain-water off the walk. Two-storied watchtowers are built at approximately 400m (437ft) intervals. The top stories of the watchtower were designed for observing enemy movements, while the bottom was used for storing grain, fodder, equipment, and later, gunpowder. The highest watchtower at Badaling is reached only after a steep climb, but the magnificent vista you find at the top is well worth the effort. You will look over mountains rising one behind the other until they finally fade into a distant haze.
