To the north of the Bismark Sea lie the Island group of the Admiralty Islands, the main island being Manus Island. Surrounding Manus, south east and west are Islands some low lying coral atolls and others with small mountain peaks. Being so close to the equator this region is predominantly calm in weather terms. The seas are some of the bluest in the pacific and dive sites gain the awe of seeing seemingly forever when diving. Some of the most remote island groups are between Manus and the mainland, the warm friendly villages here are sailors and seafarers. There is a particular location here where it is common to see 50 plus mantas at any one time
