Hikkaduwa coral Sanctuary is a typical shallow fringing reef with an average depth of around 5 metres (16 ft). The coral reef reduces the coastal erosion and forms a natural breakwater. The coast of the national park extends four km. Generally the coast is narrow, ranging from 5–50 m according to the climatic conditions of the year. Scuba diving is a popular recreation here.
