For serious divers, Derawan offers an enticing combination of rich marine life, diverse dive sites, and relatively uncrowded waters. The remote location in East Kalimantan, Indonesia, demands careful planning but rewards adventurers with encounters that range from majestic mantas to intricate macro life. Whether you choose the comforts of a resort or the adventure of a liveaboard, understanding the best times to visit and dive is key to maximising your experience.
Understanding Derawan’s Dive Seasons
Derawan’s diving calendar is unique: while diving is possible throughout the year, conditions peak from June through October. During these months, the region experiences drier weather, which brings calmer seas and improved visibility. Divers can expect underwater visibility ranging from 10 to 25 metres during this period, allowing for spectacular views of the vibrant marine life. The water temperature remains a comfortable 27–30°C, ensuring warm diving conditions suitable for extended time underwater.
Outside of these peak months, particularly from November to May, the region can experience more rainfall. While diving remains feasible, the increased precipitation can lead to reduced visibility and slightly rougher seas. Divers visiting during this time should be prepared for slightly less predictable conditions. However, those willing to embrace the variability are often rewarded with fewer crowds and unique marine encounters.
Marine Life Highlights
The Derawan Islands are a haven for marine biodiversity. Signature species include manta rays, whale sharks, green and hawksbill turtles, and a variety of macro critters. Sangalaki Island, a short boat ride from Derawan, is renowned as a manta ray hotspot, offering divers and snorkellers the chance to witness these gentle giants in their natural habitat. The island is also a significant turtle nesting site, making it an excellent location for observing these ancient mariners.
For those interested in macro photography, the Derawan and Maratua area offer a wealth of opportunities. Nudibranchs, crustaceans, and small reef fish abound, providing endless subjects for underwater photographers. The Maratua Channel, known for its strong currents, attracts large schools of barracuda and other pelagic species, making it an exhilarating dive site for experienced divers.
Accommodation and Dive Options
Derawan offers a range of accommodation and diving options, catering to different preferences and budgets. The Derawan Dive Lodge, operated by Tasik Divers, provides beachfront accommodation with air-conditioned rooms and private bathrooms. The lodge’s on-site dive centre offers guided dives, boat dives, and snorkelling excursions, ensuring a comprehensive diving experience.
For those seeking a more immersive experience, the Ilike liveaboard offers itineraries that include Derawan and Maratua. Positioned as a mid-range option, it provides good value compared to pricier Indonesian liveaboards. This option is ideal for divers eager to explore a broader range of sites without the daily return to a land-based resort.
Travel Logistics
Reaching Derawan requires a bit of planning but is well worth the effort. The most common gateway is Berau, Kalimantan, accessible via domestic flights from major Indonesian cities. From Berau, travellers typically undertake an overland transfer followed by a boat transfer to the islands. This journey, while somewhat lengthy, is part of the adventure and adds to the remote charm of the destination.
Once on Derawan Island, daily boat dives are the norm, allowing access to a variety of dive sites. Operators like Derawan Dive Lodge provide small group dives, enhancing the personalised experience. For divers interested in exploring beyond Derawan, liveaboards offer itineraries that include nearby islands like Maratua, Sangalaki, and Kakaban.
Unique Dive Sites
Derawan offers a range of unique dive sites, each with its own appeal. Kakaban Island is famous for its non-stinging jellyfish lake, a rare ecosystem where divers and snorkellers can swim with these gentle creatures without fear of stings. The Maratua Channel, known for its strong currents, offers thrilling drift dives and the chance to see large pelagics.
Sangalaki Island, aside from its manta encounters, is home to lush coral gardens teeming with life. The island’s surrounding waters are also a prime location for spotting turtles. For macro enthusiasts, sites around Derawan and Maratua offer a rich tapestry of small marine life, perfect for photographers seeking detailed shots.
Planning Your Dive Adventure
Planning a dive trip to Derawan involves considering several factors, including the time of year, accommodation preferences, and desired dive experiences. Many operators offer package deals that include accommodation, meals, and daily dives, typically ranging from USD 60–100 per day for two-tank boat dives. These packages provide good value, especially when considering the quality of the diving and the remoteness of the location.
Travellers should confirm availability and pricing directly with operators, as these can vary based on the season and specific requirements. For those interested in a liveaboard experience, booking well in advance is recommended to secure a spot on popular itineraries.
Enhancing Your Derawan Experience
To truly make the most of a Derawan diving trip, consider incorporating additional activities such as snorkelling with whale sharks or visiting the turtle conservation sites. Many operators offer excursions that combine diving with cultural experiences, providing a more comprehensive understanding of the region.
For divers certified in enriched air diving, the availability of Nitrox at the Derawan Dive Lodge can enhance dive times and safety, particularly in deeper or more demanding dive sites. Booking in advance and confirming Nitrox availability is advisable due to logistical variations.
Exploring the Surrounding Islands
In addition to Derawan, the surrounding islands of Maratua, Sangalaki, and Kakaban offer unique diving experiences. Maratua is known for its large pelagic encounters and is a must-visit for those looking to dive with barracuda and eagle rays. The island’s channel is a thrilling dive site where currents bring in a diverse range of marine life.
Sangalaki, celebrated for its manta ray population, also offers beautiful coral gardens that are ideal for both diving and snorkelling. The island’s conservation efforts have made it a sanctuary for turtles, offering a chance to see these creatures up close. Meanwhile, Kakaban’s jellyfish lake provides a once-in-a-lifetime experience of swimming with non-stinging jellyfish, adding an unusual but fascinating dive to your itinerary.
Preparing for Your Dive Trip
Preparation is key when planning a dive trip to Derawan. Ensure your diving equipment is in good condition and consider renting gear locally if needed. It’s advisable to bring a reef-safe sunscreen to protect the delicate marine ecosystems. Additionally, having comprehensive travel insurance that covers diving activities is essential for peace of mind.
Understanding local customs and regulations is also important. Respect for marine life and adherence to sustainable diving practices help preserve the underwater environment for future generations.
