Three Kings

Three Kings is one of the most dramatic and remotely positioned advanced dive sites in the Vietnam coastal reef zone — a group of three reef pinnacles or rock formations in the outer waters north of Nha Trang at depths reaching approximately 40 meters (about 130 feet), pushing into deep technical diving territory and offering experienced divers the pinnacle experience of exposed, deep South China Sea reef diving. The Three Kings site — named for the three distinct structures that form its underwater geography — creates the classic pinnacle diving experience: isolated hard substrates rising from the deep sand floor concentrate marine life from the surrounding open water in dramatic density, creating micro-ecosystems of extraordinary productivity relative to the surrounding seafloor. At 40 meters, the deepest sections of Three Kings sit at the very limit of recreational diving depth and require careful gas management, advanced decompression awareness, and comfort with the effects of depth that are essential for safe enjoyment of this extreme environment. The pinnacles are colonized by the deep-water reef community typical of the South China Sea's outer reef zones: black coral trees appear at the deeper sections, their dark branches hosting small crustaceans and basketstars. Large gorgonian sea fans of impressive age and size occupy positions on the pinnacle faces. The fish community at these deep, isolated structures skews large and pelagic: dogtooth tuna, Spanish mackerel, and various jack species circle the pinnacles in purposeful loops. Reef sharks — whitetip and grey reef species — are commonly encountered. The occasional whale shark or hammerhead passes through this section of the South China Sea on seasonal migrations. Three Kings rewards only the most experienced and technically prepared divers.
