Geography
Lok Ma Chau lies just south of the Sham Chun River, which forms the border between Hong Kong and mainland China. Lok Ma Chau lies opposite Huanggang in Shenzhen, China.Lok Ma Chau lies within Hong Kong's Frontier Closed Area, a buffer zone established by the Hong Kong government to prevent illegal immigration from mainland China, and access to the area is restricted to those holding Closed Area Permits. Those who are crossing the border to or from China do not need permits but must leave the area immediately after completing immigration procedures.
To the southwest of Lok Ma Chau is the Mai Po Wetlands.
Lok Ma Chau Loop
Following the river straightening efforts on the Sham Chun River, Lok Ma Chau Loop, which was once previously linked to Shenzhen adjoined Hong Kong. Consequently, it was officially incorporated into Hong Kong's jurisdiction in 2017.The proposed Lok Ma Chau Loop Innovation and Technology Park is located just east of the border post and will be expected to generate up to 1.2 million square metres of additional office space when completed.
