North Sulawesi: a rich and diverse area
North Sulawesi is almost exclusively visited by divers. Why this is, will quickly become clear. It has one of the richest and most varied underwater landscapes on earth. Specialists say that in Bunaken National Park alone, one can find more than 58 different coral species and subspecies and about 2,000 species of fish. These numbers grow even larger if you start counting the other species in the Archipelago of Bangka and Lembeh Strait. Thalassa organizes trips to most of these extraordinary dive sites in this rich area.
North Sulawesi is part of the island where three large bodies of water come together: the Pacific Ocean, Sulawesi (Celebes) Sea and the Indian Ocean. Together they are an important food source for numerous species. The tidal flow and variety of underwater landscapes also contribute to the richness of this treasure under the sea.
The sea around North Sulawesi can be roughly divided into five different dive areas.
Together they offer over 150 different dive sites, suitable for all levels.

Water Temperature
The tidal range in the area is about 2.2 meters and therefore most dives are drift dives. The water temperature varies between 26 and 29 degrees Celsius. Sunburn occurs rapidly and often without you noticing. This is because of the cooling effect of the water. Most divers and snorkelers therefore wear a 3mm shorty or full suit.
