Sham Chun River
Border Road () is a road along the south bank of Sham Chun River, and the northernmost road in Hong Kong. Since January 2016, it is amongst the only remaining places within the Frontier Closed Area (along with an area around and within parts of Sha Tau Kok). Currently it is used for patrolling purposes only and public entry is forbidden. It starts from Mai Po Nature Reserve in Yuen Long and ends along Lin Ma Hang Road.
