Blue Corner is a section of Palau's barrier reef in the south-east of Koror, close to Ngerukewid and German Channel. Its triangular shape, with step walls on the Pacific Ocean sides, resembles a submerged peninsula. In the north part of the Blue Corner, there is a large underwater cavern called Blue Holes. Due to a high variety of corals and wildlife in the area, the Blue Corner is a popular recreational dive site.[1] It is variously called "the most requested dive in Palau"[2] and "one of the most action-packed scuba dive sites in the world."[3]
