The Bunaken National Marine Park was formally established in 1991 and is among the first of Indonesia's growing system of marine parks. The park covers a total surface area of 89,065 hectares, 97% of which is overlain by sparkling clear, warm tropical water. The remaining 3% of the park is terrestrial, including the five islands of Bunaken, Manado Tua, Mantehage, Nain and Siladen. Although each of these islands has a special character, it is the aquatic ecosystem that attracts most naturalists.

The waters of Bunaken National Marine Park are extremely deep (1566 m in Manado Bay), clear (up to 35-40 m visibility), refreshing in temperature (27-29 C) and harbor some of the highest levels of biodiversity in the world. Pick any of group of interest - corals, fish, echinoderms or sponges - and the number of families, genera or species is bound to be astonishingly high. For example, 7 of the 8 species of giant clams that occur in the world, occur in Bunaken.

The park has around 70 genera of corals; compare this to a mere 10 in Hawaii. Although the exact number of fish species is unknown, it may be slightly higher than in the Philippines, where 2,500 species, or nearly 70% of all fish species known to the Indo-western Pacific, are found.

On the island you have the choice amongst a number of homestays, with rates starting at around Rp. 80 000 per day and person incl. fullboard. If you only go for the cheapest option don't complain afterwards if the water in your mandi (bathroom) doesn't get filled up regularly, or food isn't quite as nice as you had hoped for. Life in North Sulawesi in general isn't as cheap as in other regions of Indonesia, and most things on Bunaken have to be brought in from Manado. Depending on the season even fish can be pretty expensive. Better think twice before you try to bargain down prices which are already cheap; for the locals it could mean the difference between being able to eat 3 or only 2 meals a day, or buying school books for the children or not.
Some of the dive operations on Bunaken are offering more upmarket accommodation, even hot showers (Living Colours, Cha Cha Nature Resort).
