Hong Kong UNESCO Global Geopark (Chinese: 香港世界地質公園), formerly Hong Kong National Geopark (香港國家地質公園), was inaugurated on November 3, 2009. It covers an area of 50 km2 across parts of the Eastern and Northeastern New Territories. It includes eight sites (and combinations of sites). On September 18, 2011, UNESCO listed the Geopark as part of its Global Geoparks Network. The Geopark is made up of eight Geo-Areas distributed across the Sai Kung Volcanic Rock Region and Northeast New Territories Sedimentary Rock Region.
