The nation of Papua New Guinea contains the eastern half of the island of New Guinea, as well as the islands of New Ireland, New Britain, and Bougainville, in addition to numerous smaller islands.
Much of the country is mountainous and covered in tropical rainforests, as the New Guinea Highlands, a chain of mountains and river valleys, runs the length of the New Guinea island.
The highest point of Papua New Guinea is Mount Wilhelm at 14,793 ft (4,509 m).
Rivers of note include the Sepik River which winds its way through lowland swamp plains to the northern coast, and the Fly River which flows through one of the largest swamplands in the world on its way to the south coast of the island.
