Geographia.com - Papua New Guinea
Papua New Guinea occupies the eastern half of the rugged tropical island of New Guinea(which it shares with the Indonesian territory of Irian Jaya) as well as numerous smaller islands and atolls in the Pacific. The central part of the island rises into a wide ridge of mountains known as the Highlands, a territory that is so densely forested and topographically forbidding that the island's local peoples remained isolated from each other for millennia. The coastline is liberally endowed with spectacular coral reefs, giving the country an international reputation for scuba diving. The smaller island groups of Papua New Guinea include the Bismarck Archipelago, New Britain, New Ireland and the North Solomons. Some of these islands are volcanic, with dramatic mountain ranges, and all are relatively undeveloped.
