Bunaken National Marine Park

With 390 species of coral, 2000 species of fish make the protected park of Bunaken a truly special destination for diving in North Sulawesi. The biodiversity and colors are spectacular and every dive is a chance to discover something. On top of that, the park’s wide reefs are excellent for snorkelers as well.

Lembeh Strait

As a more recent addition to the canon of diving locations, the Lembeh Strait has already earned its stripes as a remarkable diving hotstop. Here, you can find some of the most bizarre and well-camouflaged critters. Come and witness the grand spectacle of life on a tiny scale, whether it’s on the black volcanic sand or the coral gardens.

Bangka Archipelago

At a point where the Celebes Sea and the Molucca Sea meet, the currents bring in nutrients in an area where spectacular volcanic topography is home to a convergence of rich underwater life. This is a dive adventure you cannot afford to miss!
