Shaped like a teardrop, the island of Sri Lanka measures about 255 miles (415 km.) from north to south, and about 135 miles (220 km.) from east to west, with a total land area of about 25,300 square miles (65,600 square km.). It has more than 830 miles (1340 km.) of coastline. The island is ringed by a broad coastal plain, rising to an inland terrain of gently rolling hills. A range of mountains dominates the south-central interior, with the highest peak, Mt. Piduruthalagala, reaching more than 8200 feet (2524 meters) in height.
