Dive Site: Makassar Reef (Manta Alley)

About Makassar Reef (Manta Alley)

Makassar Reef, commonly known as Manta Point, is a premier dive site in Komodo National Park, located in the central zone between Komodo and Rinca Islands. This expansive, shallow reef flat, stretching for approximately three kilometers, is celebrated for its reliable encounters with reef manta rays. The site serves as a vital feeding ground and cleaning station for these magnificent creatures, attracting them with nutrient-rich waters and specific coral outcrops where smaller fish remove parasites. The topography consists primarily of a sandy and rubble plateau, ranging from 5 to 15 meters deep, occasionally reaching 18 meters. While the coral reef itself may not be as visually spectacular as some other Komodo sites, its ecological importance for mantas is paramount. The prevailing currents transform it into a gentle drift dive, allowing divers to effortlessly glide along and observe mantas feeding or visiting cleaning stations. Mantas are present year-round, with peak activity often observed between October and May. Beyond the mantas, divers can spot eagle rays, reef sharks, leopard sharks, and various macro life like blue-ringed octopuses and nudibranchs in the sloping reef areas. This combination of abundant marine life and relatively shallow, accessible depths makes Manta Point an ideal location for both certified divers and snorkelers, solidifying its status as one of Komodo's most famous and frequently visited dive sites.

Conditions & Currents

Manta Point is primarily dived as a drift, with currents ranging from mild to moderate on most tides, though they can occasionally be strong. Divers typically enter up-current and allow the flow to carry them along the plateau, observing cleaning stations. The site's shallow nature, generally 5 to 15 meters deep, makes the drift manageable for open water certified divers with good buoyancy control. However, awareness of current changes and maintaining proximity to the guide are crucial. Visibility typically ranges from 10 to 20 meters, but can decrease when plankton concentrations are high, which paradoxically indicates prime manta feeding conditions.

Dive profile & how the dive runs

Dives at Manta Point typically begin with a back-roll entry up-current, particularly if mantas are spotted from the surface. If not immediately visible, the group will drop in at the up-current end of the site with positive buoyancy. The dive then proceeds as a gentle drift along the shallow, predominantly flat rubble bottom, which ranges from 5 to 15 meters deep. The objective is to scour the area for mantas feeding on plankton or visiting one of the many cleaning stations. Divers maintain a relaxed pace, drifting with the current, while keeping an eye out for mantas hovering or gracefully moving. Should mantas be found at a cleaning station, the group positions itself carefully to observe without disturbance. Towards the end of the dive, if conditions allow, the drift may carry divers towards a gently sloping reef area, offering a chance to explore corals and macro life for the final part of the dive and during the safety stop.

Underwater photography

Manta Point is a prime location for wide-angle photography, specifically for capturing the reef mantas. Due to the shallow depth and potential for bright ambient light, strobes are highly recommended to bring out the colors and details of the mantas and any accompanying marine life. When mantas are at cleaning stations, approach slowly and maintain a respectful distance to avoid scaring them off. For feeding mantas, anticipate their paths and position yourself calmly to capture them mouth agape. Given the potential for plankton-rich waters, visibility can be slightly reduced, requiring careful composition. For macro subjects like blue-ringed octopuses or nudibranchs found in the sloping reef sections, a macro lens with focus lights will be essential.

Getting there & logistics

Access to Manta Point is typically from Labuan Bajo, Flores, which is serviced by Komodo International Airport (LBJ). From Labuan Bajo, it's approximately a 45-minute to two-hour boat ride, making it a staple on most daily dive trips. Liveaboard itineraries, especially those focusing on Central and South Komodo, also frequently visit Manta Point. A 3-day Komodo package will typically include this site. Komodo National Park fees, which include diving permits, are usually incorporated into dive trip pricing by operators. For dedicated manta enthusiasts, multi-day liveaboards are recommended as they offer multiple dives at the site across varying conditions, significantly increasing the chances of diverse manta encounters.

Safety & environment

While Manta Point is considered accessible, certain safety considerations are important. Komodo's currents can be unpredictable, and while usually mild to moderate here, strong currents can occur. Divers should be proficient in drift diving techniques and maintain excellent buoyancy. It is mandatory to carry personal dive insurance, and options like DAN are available locally. The nearest recompression chamber is in Denpasar, Bali, highlighting the importance of cautious diving and immediate evacuation plans. Oxygen and comprehensive first aid kits are standard on reputable dive boats. Always follow your dive guide's instructions regarding current conditions, entry points, and manta interaction protocols to ensure both diver safety and the well-being of the marine life.
