Ring of Fire
The volcanoes of North Sulawesi are part of the "Ring of Fire" around the Earth. Of course you can visit volcanoes on the mainland, but you can also do so under water. Traces of their activity can be found in the north, at a dive site called 'Paradise Jetty. Here hot water comes up from the seabed.
While diving in this extraordinary archipelago it soon becomes clear that this is relatively new area where most species of hard coral haven’t even had the chance to grow yet.
Basalt rocks
Under water, basalt rocks are covered with the most amazingly colored soft corals. Around the pillars, large schools of yellow snappers have the time of their lives. And the many caverns and sponges form the perfect hiding place for many small but interesting sea creatures. It is nature at its best. Because of the waves, the visibility is not always as good as around the sites of Bunaken National Park, but this area is not something you want to miss.
