The Admiralty Islands are a group of 18 islands in the Bismarck Archipelago. These are also sometimes called the Manus Islands, named after the largest island. The islands form part of Manus Province of Papua New Guinea. The total area is 2100 km².
The larger islands in the group include Manus Island, Los Negros Island, Tong Island, Pak Island, Rambutyo Island, Lau Island, St Andrews Islands, Baluan Island, and Ndrova Island. Many of the islands are atolls and uninhabited.
The temperature of the Admiralty Islands varies little throughout the year, reaching daily highs of 30-32°C and 20-24°C at night. Average annual rainfall is 3,382 mm and is somewhat seasonal, with June-August being the wettest months.
Manus reaches an elevation of 700m and is volcanic in origin and probably broke through the ocean's surface in the late Miocene, 8-10 million years ago. The substrate of the island is either directly volcanic or from uplifted coral limestone. The vegetation is broadly described as lowland tropical rain forest.
