Pulau Mantanani is a group of three isolated islands northwest of Kota Belud, 80 km north of Kota Kinabalu. It was so isolated in fact that not until recently, only a few locals knew the existence of the islands.
But most popular attraction of Pulau Mantanani are the dugongs (sea cows). Here you can swim with them. The island is virtually unknown to most people, although the indigenous Ubian fishing tribe here have for years sighted dugongs.
The sheltered bays around the Mantanani Islands seem to provide the ideal habitats for dugongs. Sea grass beds are found on shallow sandy areas within the encircling fringing reef of the islands. A small human population has caused minimum pollution and there is little noisy boat traffic.

Near Mantanani Islands many local fishermen have seen dugongs for as long as they can remember, although the sightings are less frequent in recent times. Fortunately, the local people are not used eating dugongs.
