Dive Site: Mount Nila

About Mount Nila

Mount Nila is a volcanic island situated in the remote Banda Sea, part of the Forgotten Islands chain. This region, often accessed via liveaboard, is celebrated for its pristine marine ecosystems and dramatic underwater topography. The island is one of the isolated structures rising from deep ocean floors, characterized by exceptional coral coverage and nutrient-rich upwellings that sustain a vibrant ecosystem. As a volcanic island, Mount Nila contributes to the unique geology of the Banda Sea's 'Ring of Fire,' where cold, deep water rises along seamounts and volcanic islands. This phenomenon creates abundant plankton blooms, attracting large pelagic species and schooling fish to its flanks. Diving around Mount Nila offers encounters with a wide array of marine life, from schooling hammerhead sharks to diverse reef inhabitants. The area boasts healthy hard corals and pristine walls, benefiting from its remote location and minimal human impact. Divers can expect excellent visibility, making it an ideal spot for observing both macro and large pelagic species. Access to Mount Nila is exclusively by liveaboard due to its remote setting within the Forgotten Islands. This allows for immersive diving experiences in uncrowded waters, typically involving drift dives along its walls and seamounts. The conditions can be variable, ranging from mild to strong currents, which contribute to the dynamic marine environment and attract a variety of species.

Conditions & Currents

Currents around Mount Nila, like much of the Banda Sea, can be variable, ranging from mild to strong, offering dynamic dive conditions. The strength of the current is largely influenced by the lunar cycle and the specific dive site's topography, often being stronger in passages between islands and around seamounts where nutrient-rich waters upwell. These current-swept areas create exhilarating drift dives and are prime locations for encountering larger pelagic species. Divers should possess a basic understanding of diving in currents, and those with advanced open water certification and experience in currents are strongly recommended due to the potential for demanding conditions. Visibility is generally excellent, typically between 15 to 30 meters, and can extend up to 40 meters on good days, although thermoclines are possible due to deep-water upwelling.

Dive profile & how the dive runs

Diving at Mount Nila typically involves exploring pristine walls and seamounts that rise from considerable depths. Entry is usually via tender, often as a negative entry to quickly descend and avoid surface currents. The profile will depend on the specific site, but divers can expect to drift along coral-covered slopes and walls, with depths ranging from shallow reefs down to 30-40 meters or more. Due to the pelagic nature of the sites and deep-water proximity, divers should maintain awareness of their depth and no-decompression limits. The route is often guided by the current, allowing for observation of schooling fish and larger pelagics drawn to the nutrient-rich upwellings. Turn points are determined by air consumption and current direction. Safety stops are typically performed in the shallower parts of the reef or in the blue, sometimes trailing a surface marker buoy for boat pick-up.

Underwater photography

Mount Nila's excellent visibility and diverse marine life offer fantastic opportunities for both wide-angle and macro photography. For capturing the extensive coral walls and schools of pelagic fish, including hammerheads, a wide-angle lens is essential. External strobes are recommended to bring out the vibrant colors of the hard corals and ensure proper exposure of larger subjects against the blue water. When focusing on macro subjects like nudibranchs or seahorses, a macro lens will capture the intricate details found on the reef. Practicing excellent buoyancy is crucial, especially when navigating currents or close to the fragile corals. Maintain respectful distances from marine life, particularly schooling pelagics, and avoid chasing or disturbing animals. Given the potential for strong currents, ensure your camera setup is secure and easy to handle in dynamic conditions.

Getting there & logistics

Access to Mount Nila, located in the remote Forgotten Islands chain within the Banda Sea, is exclusively via liveaboard. International flights typically arrive in Jakarta (CGK) or Bali (DPS), followed by domestic flights to embarkation ports such as Ambon (AMQ) or Saumlaki (SXK). Trips generally range from 7 to 14 nights, allowing liveaboards to cover significant distances between diverse dive sites across the Banda Sea and Forgotten Islands. These itineraries often combine several of the 'strongest' sites, including the central Banda Islands, offshore seamounts like Manuk and Nil Desperandum, and other Forgotten Islands sites like Mount Nila. Due to the remoteness, there are no specific park fees mentioned for individual sites like Mount Nila, but liveaboard costs typically cover all necessary permits and port fees. Booking during the optimal dive seasons (April-May, August-October) is crucial to ensure calm seas and access to these exposed locations.

Safety & environment

For diving Mount Nila, comprehensive dive accident insurance, such as that provided by DAN, is highly recommended due to the remote nature of the Banda Sea. The nearest recompression chambers are located in larger Indonesian cities like Denpasar (Bali) or Jakarta, making evacuation a significant logistical challenge and potentially lengthy process. Divers must be self-sufficient and follow strict dive protocols. Site-specific hazards include variable and potentially strong currents, which necessitate good buoyancy control and careful dive planning, including gas management and understanding drift diving techniques. Always dive with a surface marker buoy (SMB) for easier surface pick-up. Respect marine life, especially large pelagics, maintaining a safe distance. Always adhere to your dive guide's instructions, particularly regarding entry and exit procedures and managing unpredictable conditions.
