Dive-site story
Located off the rugged northern coastline of Green Island, Bai Niu Du features submerged volcanic boulders, stepped coral terraces, and deep gullies carved by oceanic surges. Divers drift along dramatic rock formations covered in gorgonian fans and healthy stony coral colonies. The offshore flow brings nutrient-rich water that regularly attracts cruising pelagics alongside resident reef species.
Volcanic underwater terrain featuring rocky ridges, crevices, and large sea fans
Regular encounters with green sea turtles and sea snakes cruising the reef flats
Kuroshio-fed oceanic currents that draw schools of trevally and barracuda
