Diving in Sangalaki, Kakaban & Maratua

Derawan archipelago in north east Kalimantan is one of the most remote areas of Indonesia. Here you can find an archipelago that offers truly spectacular world class diving among its 5 islands, Derawan, Maratua, Kakaban, Sangalaki and Pulau Sambit

Diving the Derawan archipelago

Discover an untouched diving destination which offers everything you need for the ultimate dive safari. Located off the East Coast of Kalimantan (The Indonesian portion of Borneo) the Islands of Sangalaki, Maratua and Kakaban offer some of the most remote, uncrowded and untouched diving spots visited by the Manta fleet. Not only will you be diving away from the crowds but the diving is spectacular with plenty of ‘Big Fish’ sightings possible throughout the area.


Good potential for manta rays who use the island's surrounding colourful reefs as a cleaning and breeding ground. To the North of the island are Manta avenue, Manta parade and Manta run - where the manta rays may be found feeding on a rich supply of plankton just meters from the beach. The mantas can sometimes be seen cruising down these manta highways, whilst other rays forage around for food under the sand together with the goatfish. Their wing tips break the surface at regular intervals as they circle around you. They prefer to swim close to the surface, so snorkeling or free diving is also a good way to interact with them. Sangalaki is also a renowned turtle hatching site, every day hundreds of hatching sea turtles can be seen making their dash to the ocean from their nesting sites.

Kakaban & Kakaban Lake

Kakaban is famous for it’s stunning fresh water Jelly Fish lake fringed by virgin Mangrove forest Thousands of years ago the island was naturally uplifted which isolated the marine ecosystem from the surrounding seas making all biota in this marine lake very unique with endemic critters such as four species of non-stinging jellyfishes and non-stinging anemones. Marine biologists have also found a number of unknown species of anemones, tunicates, flatworms and crustaceans in the lake. This truly is a biological paradise where everything can easily be seen snorkelling.On the seaward side of the island sheer drop offs and walls attract Huge schools of Trevally and Barracuda along with the possibility of Hammerhead, Grey Reef and Black Tip sharks.


One of the most action filled destinations in the region, the walls that surround this island provide some great Big Fish dives, with massive schools of chevron barracuda, hunting trevally, thresher sharks and much much more! There are several impressive drop offs and a drift dive can be done through the channel into the lagoon. The channel entrance is at 27 meters and the strong currents attract these large pelagics. Best time to dive the channel is on an incoming or slack tide where marine life reaches a crescendo of activity, whilst coral growth is not as spectacular here due to the strong currents, pelagic action can be simply awesome!

What to see / Highlights

Plenty of pelagic action; manta rays, barracuda, jacks, tuna, a variety of reef sharks, even Leopard & Thresher sharks can be spotted here. Reef; amazing soft corals, turtles, harlequin shrimps, frogfish, ribbon eels, cuttlefish, nudis, & usual suspects. There is a place to see Whale Sharks here. However, it is not guaranteed. Dives searching for the whale sharks take place around fishing ‘Bagans” (floating fishing platforms) and are located away from any reefs in the open sea. It is a risk worth taking in our opinion, mostly they are there and, well, they are the biggest fish so very very popular!

Amazing Island Highlights

Whilst the diving in this region is fantastic there are also a couple of land based, island visits that should not be missed! We will have a chance to visit the beautiful fresh water Jelly fish lake at Kakaban, a short trek over an easy walk way through lush tropical jungle leads to this stunning and tranquil lake, an experience you will never forget! We also visit the beach at Sangalaki to witness baby turtles hatching & running to the sea - an amazing experience!

Please Note; these land based excursions mean substituting a dive, there is not always time to plan for these activities along with 4 dives. If guests prefer to dive & miss these excursions we can manage as we have three support vessels available.
