Dive Site: Blue Corner

About Blue Corner

Blue Corner, located off the southwest reefs of Palau's Ngemelis Island, stands as one of the world's premier dive destinations, frequently listed among the best globally. This geological marvel is a reef plateau that extends prominently into the open ocean, acting as a natural funnel for nutrient-rich currents. Its unique topography creates an unparalleled environment for an explosion of marine biodiversity. The dive site features a sea wall that plunges from 10 meters down to 330 meters, adorned with colorful corals and gorgonian sea fans. Above this, a plateau between 12 and 20 meters deep is covered in massive coral heads, including extensive cabbage corals, making it accessible for most divers. The confluence of currents at this corner attracts an incredible density and variety of marine species. Divers can expect to encounter massive schools of fish, numerous sharks, and impressive pelagics. Regular sightings include jacks, barracudas, snappers, Napoleon wrasse, and various species of turtles. Occasionally, more elusive creatures like hammerhead sharks, whale sharks, and manta rays make appearances, adding to the site's allure. The currents, while challenging, are precisely what make this site so vibrant and dynamic, delivering a constant parade of marine action. Accessing Blue Corner typically involves a 50 to 70-minute speedboat ride from Koror. Diving here often involves using a reef hook to secure oneself against the strong currents, allowing divers to passively observe the underwater drama unfold. This technique helps conserve energy and protects the delicate reef structure, ensuring a sustainable and thrilling dive experience.

Conditions & Currents

Blue Corner is synonymous with strong and unpredictable currents, which are the very lifeblood of this vibrant ecosystem. Currents can change direction both horizontally and vertically within seconds, creating an exhilarating drift dive experience. Divers commonly use reef hooks to anchor themselves to the coral plateau, allowing them to hang effortlessly in the current and observe the marine spectacle without expending excessive energy or damaging the reef. Visibility is highly dependent on these currents; incoming tides bring clear ocean water, often exceeding 28 meters, while outgoing currents can reduce visibility to around 12-16 meters. Due to these variable conditions, the dive is best suited for advanced divers with experience in current, though inexperienced divers may visit during periods of low current. Always consult your dive guide as they will assess the conditions and requi

Dive profile & how the dive runs

Diving at Blue Corner typically begins with an entry along the main reef wall or at the eastern end, descending to a cavern at approximately 22 meters. The dive then progresses along the reef, with divers using reef hooks to secure themselves to the coral plateau, which sits at depths of 12 to 20 meters. This allows for observation of the pelagic action in the strong currents. The route is largely dictated by current direction and strength, with divers often drifting along the wall before reaching the corner itself. The turn point is flexible, depending on gas consumption and no-decompression limits, but the focus remains on the action at the corner. Safety stops are often performed in shallower, more sheltered areas along the reef or as part of a controlled ascent once clear of the strongest current, under the guidance of the dive master.

Underwater photography

Blue Corner offers exceptional wide-angle photography opportunities, given the sheer volume of schooling fish, pelagics, and shark action. A wide-angle lens is essential to capture the expansive reef, the dramatic drop-off, and the large formations of marine life. External strobes are highly recommended to bring out the vibrant colors of the corals and fish in the blue water. When hooked into the reef, you gain a stable platform, which is ideal for composing shots of sharks and barracudas swimming against the current. Be mindful of your buoyancy and finning to avoid disturbing the reef or stirring up sediment. Patience is key, as the action comes and goes with the current. For specific shots of individual fish or reef sections, a macro lens can also be rewarding, particularly on the shallower plateau where numerous small creatures reside among the corals.

Getting there & logistics

To reach Blue Corner, you'll first fly into Roman Tmetuchl International Airport (ROR) in Palau, which is on the island of Babeldaob and connected by a bridge to Koror. International flights typically originate from the Philippines, Taiwan, South Korea, Japan, or Guam. From Koror, the main city, most liveaboards depart from Malakal Harbour. Blue Corner is located approximately 46 km (25 miles) from Koror, translating to a 50 to 70-minute speedboat journey. Liveaboard trips in Palau typically range from 7 to 10 days, often combining Blue Corner with other iconic sites like German Channel and Blue Holes. Divers are required to obtain a Koror State diving permit, which is often included in liveaboard packages.

Safety & environment

Diving at Blue Corner demands adherence to strict safety protocols due to strong and unpredictable currents. It is crucial to be proficient in buoyancy control and comfortable with drift diving techniques, including the use of a reef hook. Always dive with a surface marker buoy (SMB) and a dive computer. The nearest recompression chamber is located in Koror, Palau. Emergency evacuations from Blue Corner to Koror would typically involve a speedboat transfer, followed by ground transport to the chamber. Divers should ensure their dive insurance covers emergency medical care and evacuation for diving incidents in remote locations. Listening to and following your dive guide's instructions is paramount, as local expertise is vital for navigating the dynamic conditions of this site.
