This dive site is one of the most underrated sites in the park. Although, the sandy bottom and lack of current put this bay dive at the top of the list for courses, there is an abundance of life that exists here. Almost anything is possible. Turtles are always here. Cuttlefish, sweetlips, white tip sharks, and blue spotted stingrays are also frequently sighted. Siaba Besar also is a bit of a magical site when it comes to rarer creatures - dugongs, silver tip sharks, and ornate ghost pipefish have all been spotted here
