The Admiralty Islands are an archipelago group of 18 islands in the Bismarck Archipelago, to the north of New Guinea in the South Pacific Ocean. These are also sometimes called the Manus Islands, after the largest island.
These rainforest-covered islands form part of Manus Province, the smallest and least-populous province of Papua New Guinea, in its Islands Region. The total area is 2,100 km2 (810 sq mi). Many of the Admiralty Islands are atolls and uninhabited.
The larger islands in the center of the group are Manus Island and Los Negros Island. The other larger islands are Tong Island, Pak Island, Rambutyo Island, Lou Island, and Baluan Island to the east, Mbuke Island to the south and Bipi Island to the west of Manus Island. Other islands that have been noted as significant places in the history of Manus include Ndrova Island, Pitylu Island and Ponam Island.
The temperature of the Admiralty Islands varies little throughout the year, reaching daily highs of 30–32 °C (86–90 °F) and 20–24 °C (68–75 °F) at night. Average annual rainfall is 3,382 mm (133 in) and is somewhat seasonal, with June–August being the wettest months.
Manus reaches an elevation of 700 m (2,300 ft) 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 main town in the islands is Lorengau on Manus, connected by road to an airport on nearby Los Negros Island, otherwise transport around the islands is by boat. There is little tourism, although the seas are attractive to divers, including Jean-Michel Cousteau who spent time on nearby Wuvulu Island in the 1970s.
