Diving with manta rays in Sangalaki Indonesia

Sebastian Pena Lambarri

On the east coast of Kalimantan, a little south from the world famous Sipadan area, are more equally impressive, but less well-known islands & reefs.

These difficult to reach dive sites are now beginning to open up to divers - and the intrepid travelers who make it this far will not be disappointed.

Just like the Sipadan area, East Kalimantan has a lovely combination of big fish dives and critter dives. The area is most famous for its Manta Rays, which can congregate here in huge numbers. There is also a very unusual lake dive.

Best diving spots

The star of the show here is Sangalaki - a tiny island surrounded by a gentle sloping reef. The reef itself is interesting, but the real draw card are the numerous Manta Rays that feed on the plankton rich waters surrounding the island. There is no need to go deep here to find the Mantas. They normally swim just below the surface, so spending the whole dive admiring these majestic creatures is normally no problem. Most of the Mantas are black and white and around 3-4m in size, but the area also has a few, very unusual pure black Mantas, reaching 6m in size.

Maratua, also known as Big Fish Country, is another splendid site. The oddly shaped island creates a large lagoon with outer walls droping off into oblivion. As its nick-name suggests - big fish are regular visitors. Huge schools of Barracuda often engulf divers, Trevally & Tuna hunt all around and Sharks are not uncommon. Look above, and you may be lucky enough to see a school of Eagle Rays cruising by. Large Bull Rays are also seen here, along with occasional Manta sightings.

The islands off East Kalimantan are not all about big fish though. Just like the more famous sites of Sipadan to the north, there are plenty of macro delights to be found. Nestled in the lagoon created by the unusual Maratua Island, tiny Nabucco Island has Frogfish, Mandarinfish and many other weird & wonderful creatures.

Derawan Island, while not blessed with great visibility, is blessed with a wonderful diversity of critters with Flambouyant Cuttlefish, Blue-ringed Octopus, Leaf Scorpionfish, Ghost Pipefish, Ribbon Eels and Seahorses making a home here. The island, which has one resort, is also a nesting ground for Green Turtles and they are often seen swimming along the reef. Nurse Sharks & Leopard Sharks can be spotted resting on the sand during the day.

This coast also has one of the world’s most unusual dives - Jellyfish Lake. About 20,000 years ago, techtonic activity created an uplift of rock, now known as Kakaban Island. This process also completely trapped a large area of seawater in the middle of the island, cutting off the marine life inside from all outside influences and allowing it to follow its own evolutionary path.

Now, the lake is home hundreds of stingless jellyfish of four different species, plus unique sponges, tunicates, crustaceans & anemones. The lake also has its own unique species of sea snake. If you want to dive somewhere really unusual, this lake could well be it.

On the outer edge of the island are some good dive sites too. Barracuda Point, Kakaban Drop-off & Tanjung Point are all great drift dives with plenty of pelagics. There is also a deep cave here, but it is only recommended for very experienced divers with the necessary training and safety equipment.

When to dive

The East Kalimantan region has similar seasons to Sipadan, with the best diving from March through to October. January & February bring the most challenging conditions for scuba diving.

Getting there

To reach the dive resorts of Maratua and the Derawan Islands, take a flight from either Jakarta or Singapore to Balikpapan, then an onward flight to Berau. Catching an early morning flight from Jakarta or Singapore enables you to make the connection to Berau the same day. 

From Berau, it is around an hour's boat ride to the islands. Alternatively, it is possible to fly or take a boat from Tarakan in Sabah, Malaysia.

Activities

These islands are fairly remote and the main activities away from the reefs are nature-watching and simply relaxing.

Resort and liveaboard options

This is a remote location, with Maratua Atoll the main focus of the dive resorts. Expect fairly simple accomodation, but in a magical setting with outstanding diving on your doorstep.

Some resorts operate on set arrival and departure days only to allow guests to save money on boat transfer costs out to the resorts.

Some liveaboards are beginning to pay attention to this region, offering occasional itineraries for eager divers.

Apo Reef

Lying off the west coast of the Philippines island of Mindoro Island is Apo Reef, a huge coral reef system. This reef is in fact the second largest single coral reef in the world.

Tioman & Aur

Around 40km off the east coast of Peninsular Malaysia, not far from Singapore is the picturesque island of Tioman.

A popular holiday resort for Malaysians & Singaporeans, the steep-sided jungle clad slopes of the island rise straight out the water and smaller islets dot the coastline, making for a spectacular tropical dive spot.
