Raja Ampat is a group of islands on the western tip of Papua in Indonesia, famous for its diving experience. Most of the world's coral reefs biodiversity and rare species of marine life can easily be found in an archipelago about the size of Switzerland. While there are 612 islands, there are four major islands ("Raja Ampat" means "Four Kings") that have a population center: Waigeo, Misool (which is home to ancient rock paintings), Salawati, and Batanta.

Its location in Papua, one of the furthest places you can get to in Indonesia, may give you a head shake. But it's a diver's mecca that relatively advanced divers should not miss. The location of the islands, most of which are remote from the nearest towns, makes the reef pure and seemingly untouched. 

The wide area of pristine blue water contains millions of reefs and fishes, many that you will never find anywhere else. Above the ground, small but soaring islands invite you to climb their peaks, while in between your excursions the friendly locals or your crew will have fun with you. The area is much more popular with foreign tourists who seek adrenaline and natural tranquility, than with domestic ones.
