Planning your 2027 Maratua diving adventure requires precise scheduling to experience its diverse marine life and the unique Kakaban jellyfish lake. This 10-day itinerary is crafted to maximise your underwater encounters, from pelagic action around Maratua Atoll to the ethereal beauty of Kakaban, ensuring a memorable and efficient dive safari.
The Ultimate Maratua Diving 10-Day Itinerary with Kakaban Lake 2027
Maratua Atoll, a jewel in the Derawan Archipelago, offers some of Southeast Asia’s most spectacular diving. For 2027, meticulous planning ensures you capture the best of its underwater realms, including the renowned Kakaban Lake. This comprehensive 10-day Maratua diving itinerary is designed for divers seeking a full immersion into this biodiverse region, optimising for both pelagic encounters and unique geological wonders. While a 7-day Maratua diving itinerary provides a good overview, ten days allow for a deeper exploration and more relaxed pacing.
Arrival and Initial Dives: Settling into Maratua Atoll
Your journey begins with arrival at Berau (BEJ) airport, followed by a transfer to Maratua Island. The logistics for 2027 remain similar, involving a speedboat transfer that typically takes around 2-3 hours. Upon arrival, after checking into your accommodation, the first day is often dedicated to settling in and preparing your gear. Depending on your arrival time, an afternoon check-out dive at a house reef might be possible, allowing you to acclimatise to the local conditions and ensure your equipment is functioning correctly.
The first full diving day focuses on Maratua’s immediate vicinity. Dive sites such as The Channel (also known as Big Fish Country) are prime for encountering grey reef sharks, barracudas, and sometimes even thresher sharks. Drifting along the channel current provides an exhilarating introduction to the atoll’s vibrant ecosystem. Other nearby sites like Turtle Traffic or Barracuda Point offer further opportunities for large schools of fish and resident green sea turtles. This initial phase of your maratua island dive safari sets the tone for the exciting dives ahead.
Kakaban Lake Excursion and Sangalaki’s Mantas
A significant highlight of any Maratua diving itinerary is the excursion to Kakaban Island and its famous jellyfish lake. This unique geological phenomenon, a brackish water lake isolated from the sea, hosts four species of stingless jellyfish. Swimming amongst them is an otherworldly experience, a must-do for any visitor. The trip to Kakaban typically includes a short trek to the lake and ample time for snorkelling with these gentle creatures.
Following Kakaban, the boat often heads towards Sangalaki Island, renowned for its resident manta ray population. While encountering manta rays and whale sharks in Maratua is a significant draw, Sangalaki offers reliable opportunities to observe these majestic creatures at cleaning stations or feeding near the surface. Multiple dives around Sangalaki are recommended to maximise your chances of interaction. The clear waters and thriving coral reefs here also support a rich array of smaller marine life, making it a diverse diving location.
Exploring the Outer Reefs and Advanced Dive Sites
Days four to seven of the 10-day Maratua diving itinerary into more advanced and remote dive sites around the atoll. These can include sites like Eddy Point, known for its strong currents and pelagic action, or Fusilier Paradise, a vibrant reef teeming with schooling fish. Depending on the conditions and the group’s experience level, dives might extend to more challenging spots that offer deeper encounters with larger marine species.
Consider dedicating a day to exploring the lesser-frequented parts of Maratua Atoll, where pristine corals and undisturbed marine life thrive. Your dive operator will advise on the best locations based on daily conditions and recent sightings. This period allows for multiple dives at various depths and current conditions, catering to experienced divers seeking thrilling underwater experiences. The flexibility in this part of the itinerary is crucial for adapting to the dynamic marine environment.
Diving Derawan and Moving Towards Departure
As the trip progresses, a visit to Derawan Island can be incorporated, particularly if you are interested in exploring the local culture and enjoying some shallower reef dives. Derawan is also a nesting ground for green sea turtles, and night dives around the jetty often reveal turtles sleeping on the reef or hunting for food. The marine biodiversity here complements the deeper dives of Maratua and Sangalaki, offering a different perspective on the archipelago’s underwater world.
The final diving days are often used for revisiting favourite sites or exploring new ones within easy reach of your accommodation. This also allows for a gradual reduction in dive depth, adhering to safe flying regulations. For those on a maratua island dive safari, the focus shifts to ensuring a safe and comfortable transition back to land-based activities before departure. The schedule carefully considers the minimum surface interval required before flying.
