Papua and its western province West Papua, both together the western half of Papua New Guinea, is one of the last frontiers for divers. The province, former known as Irian Jaya, is highly inaccessible with not many paved roads, it is filled with jungle and many tribes still live here without knowledge of what goes on in the rest of the world. This is probably why it attracts the more adventurous diver because coral reefs and dive sites are still remote, quiet, untouched and most not even cataloged.

Up till now, the only region slightly known to divers are the Raja Ampat Islands and then in particularly Misool, Waigeo, Salawati, Kri Island and Batanta. It is thought that Irian Jaya might be blessed with the most diverse and rich underwater environments in all of Indonesia, mainly because of its widely varying topography such as walls, caves, mangroves and brackish lagoons. Many different species of fish are still discovered up till today.

In the northwest of West Papua, you can find the Raja Ampat area with the better known islands Misool, Waigeo, Salawati and Batanta, also known as the bird's head peninsular. Raja Ampat means four kings referring to the four sultans that used to rein West Papua, former called Irian Jaya. The village of Sorong is the start off point on a liveaboard trip to the Raja Ampat Islands, a stunning selection of steep mountainous islands with white sandy beaches and turquoise bright shores. Fish life is enormous mainly because the traditional Papua's don't use dynamite fishing yet and hopefully they will never have to. Aquatic life is as diverse as it can be with many kinds of tropical reef fish, pelagic and invertebrates. Sharks such as wobbegongs and the small Epaulette Shark are often found lying on the sea grass. Giant clams in all colors are found on its colorful and crowded hard coral reefs. Its variety of marine life scales directly to its stunning and changing underwater topology. You will find deep drop-offs, healthy flat coral slopes, mangroves and shallow warm water lagoons. Dolphins, manta rays, whales and turtles are some of the larger animals found here.

Misool offers stunning soft coral formation, vivid and found in all colors and shapes, while Waigeo Island is best known for encountering macro underwater life. If you are looking for large schools of fish you should visit the Kri area where currents have created a rich nutrient environment for aquatic life. Other islands that offer unforgettable sights and underwater encounters are Kawe, Minyahun, Bantang, Penemu, Wayag, Batanta and the Padaido archipelago in Biak. But there are too many islands unexplored and while diving here, your boat captain might be interested in exploring an area never dived before.
