Dive Site: Nudi Retreat

About Nudi Retreat

Nudi Retreat is a celebrated dive site situated in Indonesia's highly-dived Lembeh Strait, offering an exceptional macro diving experience. This site is particularly famous for its rich diversity of nudibranchs, giving it its name, along with abundant pygmy seahorses and sea moths. The topography features a beautiful coral bowl in the shallows, which gradually transitions into a sandy slope adorned with encrusted boulders. From this slope, two mini walls extend outwards, hosting vibrant soft coral growth that reaches up to approximately 2 meters in depth, creating varied underwater scenery. While the Lembeh Strait generally experiences warm water temperatures year-round, conditions for Nudi Retreat are optimal when visibility is clear and a moderate current is present. Such currents encourage the soft corals to open up, enhancing the site's visual appeal and making it ideal for wide-angle photography. The site is consistently rewarding for macro enthusiasts, revealing rare and unusual marine life on nearly every dive.

Conditions & Currents

Nudi Retreat typically experiences moderate currents, which are actually beneficial as they encourage the soft corals to open, enhancing the visual appeal of the site. Divers should be comfortable with buoyancy control and capable of handling drift dives. While the currents are generally not extreme, they do necessitate experience to navigate effectively, especially along the gradual slope. Staying close to the mini walls can provide some shelter if the flow intensifies. Visibility at the site is generally good but can be influenced by plankton blooms during certain transitional months, potentially reducing it to 15-25 meters. Entry and exit are primarily by boat, and the dive plan often involves letting the current assist the dive rather than fighting against it.

Dive profile & how the dive runs

Dives at Nudi Retreat typically begin with a boat entry onto the shallow coral bowl, which is a great starting point for macro photography. You will then gradually descend along the sandy slope, carefully exploring the encrusted boulders for hidden critters. The two mini walls extending from the slope offer additional areas to search for marine life. Divers usually follow the contour of the slope and walls, allowing for a progressive depth profile down to a maximum of 28 meters. The dive often concludes with a return to the shallower coral bowl, where the safety stop is performed, allowing for continued observation of smaller subjects.

Underwater photography

Nudi Retreat is an exceptional site for macro photography, so a dedicated macro lens (e.g., 60mm or 100/105mm) is highly recommended to capture the intricate details of nudibranchs, pygmy seahorses, and other small critters. Wide-angle photography can also be rewarding, especially when currents open the soft corals, showcasing the vibrant reef structure. External strobes are crucial for illuminating subjects and bringing out their true colors in the often darker, silty environment characteristic of muck diving. Practicing excellent buoyancy control is paramount to avoid stirring up the volcanic sand and to maintain a stable platform for critical focus on delicate subjects. Working closely with a guide is beneficial, as their keen eyes often spot the most elusive creatures.

Getting there & logistics

Access to Nudi Retreat is typically via liveaboard or day boats operating from dive resorts in the Lembeh Strait. The nearest international airport is Sam Ratulangi International Airport (MDC) in Manado, North Sulawesi. From Manado, it's usually a land transfer to Bitung, the main port for accessing the Lembeh Strait, followed by a short boat ride to your resort or liveaboard. Dive trips in Lembeh typically focus on dedicated muck diving itineraries, often lasting 7-10 days, allowing for multiple dives per day at various sites including Nudi Retreat. It is common for divers to combine a Lembeh trip with diving in Bunaken National Marine Park or other areas of North Sulawesi.

Safety & environment

Diving at Nudi Retreat requires adherence to standard safety protocols, including always diving within your certified limits and maintaining excellent buoyancy control to avoid disturbing the silty bottom. Given the moderate currents, proper dive planning with your guide is essential, and divers should be comfortable with drift diving. Emergency medical facilities and the nearest recompression chamber are located in Manado, requiring boat and land transfers, which can take several hours depending on sea conditions. It is strongly recommended that all divers have comprehensive dive insurance that covers emergency evacuation and medical treatment. Always follow your dive guide's instructions and local regulations.
