Best Places to Dive in the Banda Sea and Forgotten Islands

The Forgotten Islands are an arc of islands that are part of a very remote archipelago in the east of the Banda Sea. These islands are accessible only by liveaboard and offer a truly exciting adventure! The Banda Sea is famous for its deep walls, healthy reefs, giant sponges all in crystal clear blue water. This area is also now known for the chance to see schooling Hammerhead Sharks!

Nyata, Nus Leur, Terbangs and Damar

At Nyata the reefs are very healthy, especially the hard-coral formations in the shallows. Incredible fish action is attracted to the dive site here. Nus Leur is a small atoll that has a steep sloping reef with a good chance to see Napoleon Wrasse. The shallow coral garden is a very beautiful spot to do your safety stop. At North and South Terbang there are dramatic walls with large overhangs dripping with soft corals. Damar is close by and has a great hard coral garden perfect for an afternoon and night dive.

Dusborgh and Nila

Close to the island of Nila are the sea mounts of Dusborgh and Nil Desparandum. They are surrounded by very deep water so there is a chance to see large pelagics. Here we will look out for the now famous Banda Sea schooling hammerhead sharks. Absolutely massive barrel sponges and expanses of hard corals make these reefs very impressive.


Dawera is the last stop on a cruise that finishes in Saumlaki. You can dive just about anywhere around this island to find a fantastic dive site! At one point there are so many soft corals we are reminded of the glorious reefs of Raja Ampat. A huge school of Barracuda hang out on one point of the island.

There is a hidden pinnacle out from the island where the reef really is untouched. The village of Dawera does not fish here because there are so many fish around their island, they have plenty to eat! At the pinnacle the reef is a profusion of colour and each and every rock is covered in every type of coral! Big schools of jacks and batfish, schooling pyramid fish and triggerfish and hundreds of fusiliers all try to avoid the hunting reef sharks and jacks.

Forgotten Island trips are not just about the ‘big stuff’. If you want to look for macro critters we can find things like Leaf Fish, Moray Eels, lots of different Nudibranchs, Ribbon Eels, Mantis Shrimps, as well the very special Dragon Shrimps and Leopard Shrimps.

On trips from Saumlaki to Ambon we will visit Manuk. This is the most easterly volcano in Indonesia and is home to lots of sea snakes. They are very curious and divers will be approached by many snakes during the dives. But don’t worry they won’t bite, they just take a look and keep on swimming! The dramatic rocky dive sites here can be very fishy and there is a chance to spot hammerhead sharks. Above the water frigate birds and brown boobies soar over the volcano.

Banda Islands

These cruises will also include a few days in the Banda Islands. Also known as the Spice Islands, the land excursion here is fascinating. Visit the museum, an old Dutch fort and a nutmeg plantation to learn about the incredible history of these remote islands. Read more about the Spice Islands on our blog.

The diving here includes the typical deep walls of the Banda Sea, as well as sea mounts and drift dive along fish packed reefs. At Batu Kapal the whole pinnacle is covered in schooling Pyramid Butterfly Fish and Red-tooth Triggerfish which mix in with hundreds of fusiliers, creating a myriad of colour. Hammerhead sharks have to been known to visit some of the reefs here, as well as turtles, bumphead parrotfish, eagle rays and napoleon wrasse.

site of Amet Reef. Eagle rays, a huge school of jacks, hammerhead sharks and even a Dugong have all been seen here. The reef is very healthy and it is common to see bumphead parrotfish feeding in the shallows.


Another stop that you will experience on any cruise from Raja Ampat to Ambon or vice versa, is Koon. The dive site here is called Too Many Fish which is all the explanation you need! Large groupers hang out on the deep wall and there are large schools of jacks and snappers. Reef sharks and even dolphins have been seen here.

Ambon Bay

Ambon is a world class muck diving destination. Inside the bay there are numerous dive sites full of critters galore! The holy grail of fish Rhinopias can be seen here along with Frogfish, Ghost Pipefish, Nudibranchs, Leaf Fish, Zebra crabs, cuttlefish, all sorts of Pipefish, Mandarin Fish, Ribbon Eels, all sort of Eels and cute juveniles like the Barramundi Cod, Batfish and Harlequin Sweetlips.

Our eagle-eyed dive guides will be looking out for different types of shrimps such as Bumblebee Shrimp, Harlequin Shrimp, Tiger Shrimp and Coleman shrimps. In the octopus family, we might see the very special Wunderpus or Mimic and at night the Coconut, Starry Night, White-V and Long Arm Octopus come out to hunt. An excellent way to start or finish a trip!

Best Time to Go

The Forgotten Islands and Banda Sea can only be dived at certain times of the year due to weather conditions. Coralia has cruises in the Banda Sea in April when we cross down from Raja Ampat. We go to the Forgotten Islands in October and November when we cross back up to Raja Ampat. This is when the sea is at its calmest.

How to Get There

Coralia’s Banda Sea cruises involve a number of different ports. Some trips depart or arrive in Sorong. The airport code for Sorong is SOQ. Other trips depart or arrive in Ambon (AMQ). Trips also depart from Maumere on the island of Flores, the airport code is MOF. Finally, to get to Saumlaki (SXK) on the island of Tanibar, you have to fly via Ambon.
