Gubei Water Town surrounds the beautiful Mandarin Duck Lake Reservoir and leans against the Simatai Great Wall, the most dangerous and majestic section of the entire Great Wall. Regarded as 'Wuzhen in Beijing', Gubei Water Town boasts a combination of mountains, water and ancient villages. Most buildings are reconstructed in the traditional courtyard style. Based on five ancient villages and a water resource.

The Simatai Great Wall is largely in its original state, as it has not undergone much renovation like other sections near Beijing.It is situated in Miyun County, 120 kilometers (74.5 miles) northwest of downtown Beijing.This particular section, built in the early Ming Dynasty (1368-1644), is 4.5 kilometers (2.8 miles) long, with the Jinshanling Great Wall to the west. It is really a tough hike to climb the wall, but it is enormously rewarding.
