The Overhanging Great Wall, was built on a steeply sloping valley mouth. When viewed from afar, the wall looks like a magnificent painting hanging over the cliff, which is how it got its name.
Because it is very similar in appearance to the Great Wall at Badaling, it is also known as "Western Badaling".
The Overhaning Great Wall is 14 km northwest of Jiayuguan City center, and about 8 km north of the Jiayu Pass Fort. It is an extended part of the Jiayu Pass military defense system, protecting water resources and acting as a northern lookout point.
The magnificent Suspended Great Wall, completed by Gansu Patrol Commander Li Han in the 19th year of the Emperor Jiajing's reign (1540) during the Ming Dynasty, defends the northern entrance to Black Mountain Valley.
The Hanging Wall was built on a ridge with a gradient of 45 degrees, and it was made of tamped local gravel and yellow earth.
The wall was originally 1.5 kilometers (0.9 miles) long, but it is only 750 meters (0.5 miles) long now; it was renovated in 1987 with three towers, two at the ends of the wall and one in the middle.
The Overhanging Great Wall Military Defense System Area comprises the Hanging Great Wall on the steep ridge, the Water Gate in the valley, and the Ancient Weaponry Exhibition.
You can see austere panoramas from the Suspended Great Wall. For the convenience of climbing, steps were built on the wall. Despite these, it is still a steep climb to the top of the 400 steps, but it is worth the effort when looking out from the top.
The scenery is strikingly arid — north the desert extends to the horizon; there are a few oases north of Jiayuguan to the east; to the south and west are steep dry mountains and gullies.
Jiayuguan has a temperate continental desert climate, influenced by the towering Qilian Mountains to the south. The temperature difference between day and night is large. UV-radiation is high, but it can be chilly and breezy.
Winter is bleak with temperatures well below zero. May to September is the cutoff period for comfortable temperatures (average range (8–22°C or 47–72°F). In July the average temperature range gets up to 15–29°C (59–84°F).
It is about 14 km from Jiayuguan City center to the Suspended Great Wall. There is no bus to the Suspended Great Wall. You can rent a car or take a taxi from Jiayuguan City to the wall. It takes about 30 minutes.
