About Siau Island

The island of Siau lies in the Celebes Sea, 130 km north of Sulawesi island, and part of  the Sangir archipelago, the islands of which sit like stepping stones between Indonesia and the Southern Philippines.

These islands are volcanic, formed where two of the Earth’s crustal plates collide. The volcano Karangetang makes Siau particularly special. At 1,800m high, and one of Indonesia's most active volcanoes - with more than 40 eruptions recorded since 1675 - Karangetang throws out hot rocks and ash everyday. At night the volcano glows red, the red hot lava can be seen cascading down its slopes.

Karangetang has made Siau a very fertile island. This, in combination with the tropical climate, has created one of the best places in the world to grow nutmeg and cloves which are a major source of income to the island. The aroma of these spices fill the air during harvest when they are laid to dry along the road sides.

The climate is tropical, with a wet and a dry season. The wet season tends to be from October to April but the temperature is fairly constant throughout the year at a pleasant 30o to 32o C. It is slightly cooler in villages on the slopes of Karangetang.

Siau is 275,96 km² in area with a population of about  40,000, living in clean, laid back villages dotted around the island. The majority of the population are fishermen, and farmers who grow nutmegs and cloves.


Siau offers many tourist attractions in addition to Karangetang. Hot springs, amazing ocean life, great seafood and incredible white sandy beaches - and more - will make this a holiday you’ll never forget.

Siau is also home to many distinct species of birds and animals. Bird watchers can find birds unique to Siau and the neighbouring islets, including maleos.

The animal wildlife includes the siau tarsier, wooley cuscuses and the large green turtles which lay their eggs on our beach!

The Celebes Sea which surrounds Siau has deep trenches from which ocean currents bring nutrients that feed a rich and diverse marine life. As a result there are numerous dive and snorkelling sites around the island to rival those in Bunaken and Lembeh in North Sulawesi. 

Where else can you find all this, what are you waiting for?
