Indonesia - Wakatobi National Park

"Wakatobi National Park has very high marine resource potential, in terms of both species and uniqueness, with enchanting submarine landscapes. In terms of configuration, the marine waters of the park generally start flat and then slope seawards, with sheer precipices in some parts. The water depth varies, the deepest parts reaching 1,044 metres with sand and coral at the bottom. This Park has 25 chains of coral reefs, and the total circumference of the coral islands is 600 km. The National Park includes an area of 1,390,000 hectares." Source: UNESCO World Heritage Tentative List
