Cenderawasih Bay Whale Shark Diving Trip

Diving trips in the largest whale sharks sanctuary: Cenderawasih Bay

The enormous Cenderawasih Bay, in the northeast of the remote Papua, is home to the largest marine park in Indonesia, with some of the finest coral gardens and dramatic vertical walls to dive. Cenderawasih Bay is the only place in the world where it is possible to see such a large quantity of whale sharks and with such ease, and not only diving, but just snorkeling or swimming. The numerous Japanese wrecks scattered around the bay from the Second World War are another major call. Underwater exploration of the Cenderawasih region has only just begun, and we expect more surprises to emerge for these extra ordinary seas.

On the seabed of the Gulf of Dore, near the town of Manokwari, are numerous Japanese shipwrecks, sunk during the Second World War. Currently there are 6 wrecks open to divers, with the other wrecks either sat too deep for exploration or not yet located.

The Manokwari Wrecks are covered in corals and home to an enormous variety of sea life. Inside the boats and on the decks you can still see cases of grenades, ammunition, helmets, bicycles, bottles, pots, pans and plates etc. On some of the wrecks you can visit the machine rooms and the radio station.

The largest ship wreck in the Manokwari Gulf is the Shinwa Maru, a immense 120m long cargo ship that is relatively intact.

It is also interesting to note that many fish that would normally live in very deep seas, are found living Cendrawasih Bay in relatively shallow waters.
