For those with a passion for the underwater world, Derawan presents an irresistible opportunity. Located in the remote yet accessible waters of East Kalimantan, this region is a diver’s paradise. It’s especially known for advanced drift diving experiences around Maratua and Kakaban Islands. These sites promise encounters with majestic marine creatures in a setting that combines adventure with natural beauty. Whether staying on Derawan Island or opting for a liveaboard, divers find an unparalleled mix of marine biodiversity and challenging dive conditions.
Exploring the Maratua Channel
Maratua Island, part of the Derawan archipelago, stands out for its advanced drift diving. The Maratua Channel is renowned for its strong currents, offering a thrilling experience for seasoned divers. This site is not just about the rush of the drift; it’s a spectacle of marine life. Divers can expect to see schools of barracuda, large pelagic fish, and the ever-present green and hawksbill turtles. The channel’s currents attract a variety of species, making each dive unpredictable and exciting. Visibility here can range from 10 to 25+ meters, providing clear views of the vibrant underwater scenery.
The best time to dive the Maratua Channel is between June and October, when conditions are typically calmer and visibility is at its peak. This period also coincides with a drier season, enhancing the overall diving experience. Divers can choose between staying at nearby resorts, such as the Derawan Dive Lodge, or opting for a liveaboard like the Ilike, which offers value-driven itineraries including Maratua. This flexibility allows divers to tailor their experience according to their preferences and schedules.
Unique Encounters at Kakaban Island
Kakaban Island is another jewel in the Derawan crown, famous for its non-stinging jellyfish lake. This unique ecosystem is home to four species of jellyfish that have evolved without natural predators, making them safe to swim with. The lake, surrounded by dense mangroves, offers a surreal experience for both divers and snorkelers. Beyond the lake, the island’s surrounding waters are rich with diverse marine life, including macro critters like nudibranchs and crustaceans.
The drift dives around Kakaban are characterized by moderate to strong currents, providing an exhilarating ride through coral gardens and overhangs teeming with life. This area is also a hotspot for manta rays, particularly near Sangalaki Island, just a short boat ride away. For those interested in macro photography, Kakaban does not disappoint, with numerous opportunities to capture stunning images of small reef inhabitants. It is advised to dive here during the June to October window for optimal conditions and to ensure a truly unforgettable experience.
Accommodation and Dive Packages
Staying on Derawan Island offers the convenience of daily boat dives to Maratua and Kakaban. The Derawan Dive Lodge serves as a comfortable base, featuring air-conditioned rooms with ensuite bathrooms, directly on the beach. The lodge’s on-site dive center provides guided dives, ensuring a professional and safety-conscious experience. The lodge is noted for its good food quality, offering a mix of Indonesian and Western dishes in a buffet-style setting.
For those seeking a different experience, the Ilike liveaboard provides itineraries that include both Derawan and Maratua. It is positioned as a mid-range, good-value option, ideal for divers wanting to explore multiple sites without the need for daily travel to and from the islands. Both options cater to divers looking for small group experiences, with personalized guiding that enhances the quality of each dive. Prices for dive packages are generally considered affordable, with indicative pricing for two-tank boat dive packages falling in the USD 60–100 range per day.
Marine Life Highlights
Derawan is celebrated for its rich biodiversity, attracting divers from around the world. The region is a sanctuary for manta rays, whale sharks, and turtles, with frequent sightings enhancing the allure of its waters. Sangalaki Island is particularly known as a manta ray hotspot, while the broader Derawan/Berau area offers seasonal whale shark encounters, often around fishing platforms known as bagan.
The abundance of green and hawksbill turtles is a significant draw, with sightings common on most dives. For macro enthusiasts, the area’s reputation is well-deserved, with sites offering glimpses of nudibranchs and other small marine critters. Water temperatures in Derawan hover between 27–30°C, providing warm tropical diving conditions that are comfortable year-round. The diversity of marine life, coupled with the dynamic currents, creates a diving experience that is both challenging and rewarding for advanced divers.
Travel and Accessibility
Reaching the Derawan Islands typically involves a domestic flight to Berau, followed by an overland and boat transfer. This journey, while requiring multiple steps, is well worth the effort for the diving opportunities available. The region’s relative remoteness ensures a less crowded experience compared to more mainstream destinations, allowing for a more intimate connection with the underwater world.
Divers can choose from a variety of travel packages, often bundled with accommodation and boat dives. This convenience simplifies logistics, allowing divers to focus on the adventure ahead. With year-round diving possible, trips can be planned to fit personal schedules, though the June to October period is recommended for the best conditions. Whether opting for a resort stay or a liveaboard, the journey to Derawan is an adventure in itself, promising memorable experiences both above and below the water.
Diving Safety and Considerations

The Derawan Dive Lodge, a PADI-affiliated resort, ensures that dives are conducted with professionalism and attention to detail. Nitrox is available for certified divers, enhancing bottom time and safety at deeper depths. The strong currents characteristic of sites like the Maratua Channel require divers to be experienced and comfortable with drift diving techniques.
Small dive groups are a common feature of the region, allowing for personalized attention and increased safety. This approach is appreciated by divers seeking a tailored experience that aligns with their skill level and preferences.
