Dive Site: Blue Corner Nusa Lembongan

About Blue Corner Nusa Lembongan

Blue Corner, located off Nusa Lembongan, is renowned as one of Bali's most exciting and challenging dive sites, situated where strong currents sweep between Lembongan and Ceningan islands. This dynamic environment creates a dramatic underwater topography where the reef shelf drops away, and converging currents concentrate marine life in impressive densities. The site is particularly famous for encounters with the Mola Mola, or Oceanic Sunfish, especially during the colder months when these majestic creatures ascend from deeper waters. The topography consists of a sloping reef leading to a dramatic drop-off, with depths reaching approximately 40 meters. While divers typically explore the shallower areas around 20-25 meters, the deeper blue water is where pelagic sightings, including the Mola Mola, frequently occur. The currents, though strong and sometimes unpredictable, are responsible for bringing in nutrient-rich water, fostering a vibrant ecosystem of soft corals and sponges that carpet the reef. Marine life at Blue Corner is abundant and diverse, ranging from large pelagics like reef sharks, eagle rays, and schooling barracuda to smaller reef fish. The Mola Mola season, from July to October, is a major draw, although sightings are dependent on luck and specific conditions. Diving here requires careful planning and experienced guides due to the challenging currents, offering a thrilling experience for advanced divers. Visibility is generally excellent, often exceeding 20-30 meters, though thermoclines can significantly drop water temperatures.

Conditions & Currents

Blue Corner is characterized by powerful and often unpredictable oceanic currents that can reach up to 8 knots at extreme sites. These currents are a defining feature of the dive, creating an exhilarating drift experience, but they can also shift direction rapidly. Divers must be comfortable with strong currents and proficient in drift diving techniques, as conditions necessitate flexible dive plans and often negative entries. Visibility at the site is generally excellent, often between 15-40 meters, but deep thermoclines are common, especially during the Mola Mola season, bringing colder water that can drop temperatures significantly and increase air consumption. Dive centers in the area emphasize that this site is not suitable for beginners and requires advanced certification with prior current experience.

Dive profile & how the dive runs

Diving Blue Corner typically begins with a negative entry due to the strong currents. The dive plan often involves drifting along the reef edge at a depth of around 20-25 meters. Guides monitor the currents closely, adapting the route as needed to explore areas where marine life congregates. The focus is often on observing pelagic species in the blue, particularly Mola Mola during their season, which are often found at around 30 meters or deeper. Divers drift with the current, enjoying sightings of reef sharks, eagle rays, and schooling barracuda. The dive concludes with a safety stop in shallower, less current-affected areas, followed by a boat pick-up, often a live pick-up, to account for the swift drift.

Underwater photography

Blue Corner is a prime location for wide-angle photography, especially when pelagic encounters are frequent. A fisheye or wide-angle lens is ideal for capturing the Mola Mola, schooling barracuda, and expansive reefscapes. Strong currents demand excellent buoyancy control and quick reactions, so be prepared to adjust camera settings and positions rapidly. Consider using powerful strobes to bring out the vibrant colors of the soft corals and to properly expose subjects in the blue. For Mola Mola, a natural light approach can often be effective given their size. Given the thermoclines, protect your camera gear from sudden temperature changes. Focus on subjects that can be found in the shallows during safety stops, as the upper reef is also rich in colorful life.

Getting there & logistics

Access to Blue Corner is primarily via speed boat from Sanur on mainland Bali to Nusa Lembongan, a journey of approximately 45 minutes. Divers typically stay on Nusa Lembongan or Nusa Penida, where numerous dive centers operate daily trips to the site. Dive packages usually include multiple dives per day, with trips lasting several days to allow for various site conditions and increased chances of Mola Mola sightings. Most dive centers provide hotel transfers within selected areas. There are no specific marine park fees beyond standard dive operator costs, but it is always advisable to confirm with your chosen dive operator.

Safety & environment

Diving Blue Corner requires a high level of caution and adherence to safety protocols due to strong and unpredictable currents. All divers must be Advanced Open Water certified and have significant experience with drift diving. Always dive with a reputable local guide who is intimately familiar with the site and its current patterns. Maintain excellent buoyancy control and stay close to your buddy and group. Monitor air consumption carefully, as cold thermoclines can increase it. The nearest recompression chamber is in Denpasar, Bali, necessitating robust evacuation plans and comprehensive dive insurance. Always carry an SMB and know how to deploy it in case of separation. This site is not suitable for novice divers or those uncomfortable with challenging conditions.
