Located in Southeast Asia, the island of Timor is part of the Maritime Southeast Asia, and is the largest and easternmost of the Lesser Sunda Islands. To the north of the mountainous island are the Ombai Strait, Wetar Strait and the greater Banda Sea, to the south the Timor Sea separates the island from Australia, while to the west lies the Indonesian Province of East Nusa Tenggara. The highest mountain of East Timor is Tatamailau (also known as Mount Ramelau) at 2,963 meters (9,721 feet). The local climate is tropical and generally hot and humid, characterized by distinct rainy and dry seasons. The capital, largest city and main port is Dili, and the second-largest city is the eastern town of Baucau. The easternmost area of Timor-Leste consists of the Paitchau Range and Iralalaro area. This area has been proposed as the first conservation area in Timor-Leste as it contains the last remaining tropical dry forested area within the country. It hosts a number of unique plant and animal species and is sparsely populated. The northern coast is characterized by a number of coral reef systems that have been determined to be at risk.
