Yan Chau Tong Marine Park
Double Haven or Yan Chau Tong (Chinese: 印洲塘) is a harbour enclosed by Double Island, Crescent Island and Crooked Island with north-eastern New Territories, Hong Kong. Parts of the haven fall within Yan Chau Tong Marine Park to protect the wildlife of the marine creatures. It is known for its scenery and natural environment, and for the calm seas from which its English name derives. Double Haven contains many deep red coloured rocks because of iron oxide.
Plover Cove (Extension) Country Park was designated in 1979 to protect the ecology of Double Haven. It also forms a major part of Hong Kong Global Geopark, Northeast New Territories Sedimentary Rock Region.
