About Grottos
A boat-access deep-water dive at the Grottos in Nananu Passage, where several yellow soft-coral pinnacles rise out of open water and a few swim-throughs add variety. It is a current-aware Bligh Waters site that rewards incoming-tide planning and suits divers who are comfortable with exposed boat logistics, moving water, and changing conditions. Marine life is a major draw as well.
