Rainbow Bank - Kimbe Bay
Rainbow Bank in Kimbe Bay is one of the region's submerged seamounts, drawing in pelagic action. We often see schooling barracuda and tuna here, occasionally even a hammerhead shark passing by. The currents can be swift, so it's a spot best suited for experienced divers comfortable with drift diving. If you're looking for big fish encounters rather than intricate reef exploration, this is a solid choice.
