The 700 nautical mile journey takes us through a range of different land and seascapes. The trip starts in the beautiful Misool Island Group in Raja Ampat. On the south coast of Halmahera we will dive walls and drop-offs with big fish action. The small islands off the west coast of Halmahera home great coral reefs.

Dives Sites


The beauty of the Misool Island Group will carry you away. This entire region is one enormous ancient limestone basin and even has limestone as the seafloor. Those who have travelled to Palau can picture these little tropical islands covered of palms, with steep sided walls where wind and sea has worn the rock away.

The islands, or islets, are uncountable. The larger ones, like Misool itself, have canyons and lagoons speckled with white sand beaches ideal for tender boat rides. One can spend hours exploring and never see the same bay. It really is a place of great beauty both above and below the water. It's rightly being considered by the Indonesian government for national park status and by the United Nations as a world heritage site.

Misool is one of the places on earth where you´ll find the most various species of fish, hard and soft corals, sponges, worms, nudibranchs, shrimps and crabs and all kind of non-vertebrates, like cuttlefish and octopus. You will as well come across Wobbegong shark and Epaulette sharks, which you will only find in the region of “Raja Ampat“. Giant clams as well as fantastic tiny shells. Photographers as well as Videographers will have the dives of their lifetime.

Amazing reeftops where hard and leather corals compete for space, submerged pinnacles, walls and slopes all with beautiful coral growth.

In the volcanic island of Makian a fantastic view awaits as we cruise closer to the volcano looms high with the sunrise behind. With an elevation of 600m and thick vegetation this will be a sunrise to remember. The natural beauty continues below the waterline. Under the pier we have a chance to do a great muck dive with frogfish, ghost pipefish, scorpion fish and all kinds of eels amongst the coral covered pillars. In the north of Makian, colorful coral contrasts beautifully with the black sand.
