Choose your language:

The North Side

The north side of Bunaken National Park offers several steep walls of 80 to 200 feet deep.

The walls are covered with huge sponges, hard and soft corals, fan corals, whip corals and other spectacular growth.

In addition, divers and snorkellers can enjoy huge schools of fish and with the help of our experienced dive guides discover the well-camouflaged creatures that hide in small holes and between the corals on the wall. 

The South Side

The south side of the Bunaken National Park is completely different than the north. Here you’ll find sandy slopes covered with sea grass.

Sea cows grazing with their young are often seen. Underwater you will find a macro-environment: seahorses, scorpionfish (Rhinopias), beautiful nudibranchs, sea slugs and octopuses are some of the special animals that live in this shallow area. 

The Coastal Reef

The sloping reefs along the coast near Thalassa dive center offer a wide variety of nudibranchs, many species of the seahorse family, the scorpion fish family and the octopus family. And these are just a few of the more than 2,000 species that live there. Did you know that we can offer you great “muck” diving along the coastline? Mating Mandarin Fish, Mimic Octopus, Flying Gunnar, the Hairy frogfish and Scorpionfish are only a few of the critters you can encounter.
