GT Rock, in Cenderawasih Bay, feels exactly like its name suggests: a large rock formation. It's a magnet for pelagic action. We often see schools of jacks circling, and the occasional dogtooth tuna zips past. This site is a good pick for divers keen on bigger fish rather than intricate reef exploration.
