    CharacterCave dive
    StandoutExceptional marine biodiversity

    Hong Kong, off Sulawesi, often gets its name from the sheer volume of fish. Drop down onto the sloping reef and you'll often find yourself enveloped in thick schools of yellow snapper, sometimes so dense they filter the sunlight. We’ve also reliably encountered schooling batfish here, and the resident whitetip reef shark often cruises through. Look closely in the coral for scarlet soldierfish darting about and keep an eye out for blue spotted rays and the occasional turtle on the sand. It’s a solid dive for those who appreciate big schools of fish.

    Safety Notes

    Overhead environment - never enter without proper cave/cavern training, redundant equipment, and a guideline.
