StandoutExceptional marine biodiversity

Blue Corner, often paired with the Blue Holes, is where you really start to understand Palau’s reputation. We’ve seen it described as a fish aggregation device, and that feels accurate. Hook in and watch the show: schools of snapper, jacks, and chevron barracuda, sometimes so thick they blot out the sun. Sharks are a constant presence, usually grey reef, with tuna and wahoo making quick passes in the blue. It’s a drift dive, often with strong currents, so it’s definitely one for experienced divers comfortable managing their buoyancy while suspended in the flow.
