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. Sri Lanka's wildlife is as varied as the island itself, ranging from elephants and leopards to marine life and a vast number of different birds, and Sri Lanka is now one of the best places in the world to see whales, including the mighty blue whale.
