Dive sites in Palau

Blue Corner is a submerged promontory extending outward from Palau's southwestern barrier reef into open pelagic water. Swift oceanic currents sweep across the plateau, drawing immense aggregations of pelagics along the vertical drop-offs. Divers commonly deploy reef hooks onto dead rock along the plateau edge to float stationary in the flow while sharks and schooling fish patrol open water just off the wall.

Palau's Blue Holes features four distinct openings in the shallow reef plateau that funnel divers down into an expansive central cavern. Light beams stream through the ceiling apertures into the darkened chamber before opening out onto the outer drop-off, where divers often drift along the wall toward Blue Corner.

Excavated during the German colonial administration to transport phosphate from the southern lagoon to the central port, German Channel has evolved into one of the central aggregation zones for pelagic life in Palau. The dive focuses along the southwest mouth of the channel where nutrient-rich water exchanges between the outer reef and the inner lagoon. Divers typically settle into sandy patches or hover along the coral heads near the mouth to watch manta rays hover over active cleaner wrasse stations.

Lying upright on a coral shelf in a sheltered bay near Koror, this well-preserved World War II Japanese Navy reconnaissance floatplane wreck remains one of Palau's most accessible historical dive sites. Often referred to as the Jake Seaplane, the aircraft rests largely intact with its fuselage, propeller blades, and radial engine clearly discernible beneath a coat of encrusting sponges and corals.

Situated along the western barrier reef of Palau near the Ngemelis complex, New Drop Off features a dramatic vertical precipice dropping into the abyss. The site sits where tidal currents sweep over the shelf, concentrating nutrient-rich ocean water that attracts large pelagics. Divers typically drift along the wall among sprawling gorgonians and soft corals, occasionally hooking in at the corner to watch predator action.

Located in the sheltered waters behind Ngerchong Island, this site features a gentle slope dominated by expansive fields of branching staghorn and table corals. Unlike its oceanic counterpart on the outer reef, the protected lagoon setting keeps currents manageable and surface conditions calm. Divers often drift quietly over sandy channels to search for camouflaged invertebrates, juvenile fish hiding within the coral thickets, and resting reef sharks.

Siaes Corner sits along the western barrier reef of Palau, where an oceanic wall intersects the open ocean and creates a gathering point for pelagic predators. When incoming tides hit the point, divers deploy reef hooks on the plateau lip to hover effortlessly while grey reef sharks patrol the blue. Below the plateau edge, the wall plunges vertically into the abyss, adorned with large sea fans, soft corals, and schools of schooling fish.

Cut horizontally into the sheer outer drop-off along the western barrier reef, this cavernous underwater opening features massive windows framing the deep blue Pacific. Divers drop down the wall to enter the cavern's wide mouth, exploring a dramatic sheltered interior before exiting along the current-swept wall.

Situated along the outer barrier reef system of southwest Palau, this vertical drop-off plummets into the deep blue ocean. Resident sea turtles rest along small ledges and crevices or feed on the sponges growing along the vertical face. Clear oceanic water frequently sweeps past the reef, carrying schools of pelagic fish and sharks along the wall edge while the reef top supports hard coral gardens.

Located off the western reef of Palau, Ulong Channel is one of the world's premier drift diving locations. The dive typically begins outside the channel mouth where incoming currents gather grey reef sharks and schooling jacks. Once divers drift inside the cut, the flow carries them along a sandy corridor flanked by vibrant hard reef slopes, culminating in a sprawling field of cabbage coral.

Located off the western reef of Palau near Ulong Island, this passage provides an exhilarating drift dive when the tide pushes incoming clear water into the lagoon. Divers typically hook in or pause at the outer mouth to watch sharks and schooling pelagics before releasing into the sandy-bottomed corridor. The channel walls are decorated with soft corals and sea fans, leading toward an expansive, centuries-old field of cabbage coral.

Ulong Wall drops sheer into the open ocean along the western barrier reef off Ulong Island. The vertical face is encrusted with giant gorgonian fans and cascading sea whips, while pelagic predators patrol the blue just off the drop-off. Most dives here operate as drifts along the current, leading toward the mouth of the nearby channel where sharks and schooling fish congregate.

Virgin Blue Hole is a dramatic vertical shaft cut into the reef plateau south of Ngemelis Island. Divers descend straight down through an enclosed limestone chimney before drifting out through a wide cavern window into the cobalt drop-off along the outer barrier wall. Ambient light creates striking cathedral shafts inside the tunnel, contrasting sharply with the deep blue expanse outside.

Known internationally as Chandelier Cave, this system consists of five distinct chambers carved into the limestone base of the Rock Islands inside Malakal Harbor. Divers enter through a wide underwater opening and navigate through series of water-filled caverns where stalactites and stalagmites formed during prehistoric low sea levels hang overhead. Air pockets in the upper ceilings allow divers to surface inside several chambers to view the geological formations before moving to the next cavern section.

Shark City lies on the western barrier reef system of Palau, situated where the reef structure juts out into open ocean currents. The site consists of a finger-like coral ridge that slopes toward a sheer vertical drop into deep blue water. Because currents sweep past this headland, pelagic predators gather in significant numbers along the plateau edge.
