Tung Ping Chau is an island in Hong Kong, part of Hong Kong UNESCO Global Geopark. It is also known as Ping Chau (平洲). Tung is prepended to the name at times so as to avoid possible confusion with Peng Chau, another island in Hong Kong with an identically pronounced name in Cantonese. Administratively, the island is part of the Tai Po District in the New Territories.

Hong Kong has a long coastline that is full of twists and turns with many bays and beaches. Many of them are well sheltered by mountains nearby, as Hong Kong is a mountainous place. As a result, large waves seldom appear at the bays, making them suitable for human swimming.
