Situated in Gubeikou Town of Miyun County in Beijing, 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.

The water town is built on the former 5 sub natural villages of Simatai Village at the foot of Simatai Great Wall. The Simatai village was developed from Simatai Castle built during the reign of Emperor Wanli ( 1573 -1620 ) in Ming Dynasty ( 1368 – 1644 ).

It is not a historical water town, it is a replica of Wuzhen Water Town in the Southern China, has developed into a large-scale sightseeing and holiday destination. Covering an area of 3.5 square miles (9 square kilometers), the holiday resort includes two scenic districts, the Gubei Water Town and the Simatai Great Wall.

The Simatai Great Wall is a part of Gubei Water Town International Holiday Resort. Only watchtowers East 2 to East 10 open to public. It is decorated with lights at night. The Simatai West section is not opened to public. Please note that you're not able to walk toward Jinshanling Great Wall or in reverse.
