Located off the eastern coast of Borneo (East Kalimantan Province) in Indonesia, in the famous Celebes Sea. The Derawan archipelago (Derawan, Maratua, Kakaban and Sangalaki) is a group of small islands and atolls with sandy banks, and an abundance of fish life. Join us aboard the Raja Ampat Aggressor for a 7 night adventure exploring this area. The diving offers abundant marine life (sharks, schooling barracudas, mantas, whalesharks and macro life) and a huge variety of coral reef dives, caves, walls, and lagoons, including a jellyfish lake visit. Derawan also contains the largest green turtle nesting site in Indonesia, making dives with turtles quite common.
