Countless ships have come to grief in the waters of the Asia/Pacific region, victims of war, storms, piracy or poor navigation. Found in this area are everything from ancient Chinese junks carrying priceless porcelain to Spanish galleons loaded with silver and gold to more modern cargo ships. But some of the famous shipwrecks in this area were sunk in the many fierce battles of World War II.

While there are plenty of amazing individual shipwrecks in this region, like the SS Yongala or Bali’s Liberty Ship, this article is focusing on dive destinations where you can explore numerous shipwrecks during your stay. Following is a guide to the best wreck diving destinations in the Asia/Pacific region.

Espiritu Santo, Vanuatu

The small town of Luganville, on Espiritu Santo, was once a major American base during World War II and is now one of the best wreck diving locations in the world. Its main claim to fame is the former ocean liner SS President Coolidge, but there are many more wrecks worth exploring at this destination.

Sunk after hitting two mines in 1942, the 198m long SS President Coolidge now rests on its port side in depths from 18m to 70m and is a spectacular dive. The ship sank while fully loaded with war supplies, and divers today can explore every nook and cranny of this immense ship. With a ship this size, in this depth, it takes at least a week to cover all its major points of interest, but divers have been known to spend months exploring this incredible ship.

If you can drag yourself way from the Coolidge, other great wreck dives in the area include the destroyer SS Tucker, the tug boat Tui Tuate, the island trader Henri Bonneaud and the leftover war equipment dumped into the sea at Million Dollar Point.

Guadalcanal & Iron Bottom Sound, Solomon Islands

A small stretch of water separates Honiara and Tulagi, known as Iron Bottom Sound. It was once called Savo Sound, but after the massive loss of ships in this strait in World War II it was renamed and today offers incredible wreck diving. Easily accessible from the shore west of Honiara are three Japanese cargo ships – Hirokawa Maru, Kinugawa Maru and Kyusya Maru. Run aground while being attacked, the ships are broken up at their bows but more intact at their sterns, allowing some penetration.

These wrecks are also covered in colourful corals and home to fishes big and small. Also accessible from the shore is a B17 Bomber and the very broken up I1 Japanese submarine. Other wrecks off Honiara that are done as boat dives include the Japanese freighter Azumason Maru, the American Coast Guard liberty ship USS Serpens, the American attack transport ship USS John Penn and in deeper water the legendary American destroyer USS Aaron Ward – which features on most wreck-lovers’ bucket lists.

Coron Bay, Philippines

Another great collection of World War II shipwrecks can be found in the Philippines in Coron Bay, at the northern end of Palawan. Used as a secret harbour by the Japanese, the fleet was discovered and attacked by the Allies in 1944, and while the ships were later salvaged, they still offer sensational wreck diving.

The largest shipwreck in Coron Bay is the Okikawa Maru, a 168m long auxiliary oil tanker that rests upright in 26m. This ship is simply enormous, so it takes several dives to see all its features. One of the most unique shipwrecks is the Akitsushima, a 118m long seaplane tender that rests on its port side in 35m. Machine guns and the giant crane boom are just some of the features that can be seen.

Many of the Coron Bay shipwrecks are freighters, like the Olympia Maru, Kogyo Maru, Irako Maru, Kyokuzan Maru and the Morazan Maru. Other ships in the area include 20m long Lusong Bay Gunboat and the Nanshin, a 50m long tanker. Most of these wrecks are in depths between 20m to 35m. One note of warning, Coron Bay is tidal, so does have strong currents at times and the visibility can vary from 6m to 30m. However, these nutrient rich currents mean the ships are covered in incredible coral growths and play host to a wonderful variety of marine life.

The Japanese ships sunk in the waters of Palau went to the bottom in two attacks in 1944. Most of the wrecks rest in the harbour in depths between 10m and 40m, and while they don’t enjoy the brilliant visibility of the offshore reefs, they still offer exciting diving.

  1. I don’t like doing large groups, so are private dives available for some of the most popular wrecks at Chuuk?

    1. Hi Charlie, we often send solo divers to Truk Lagoon. We can enquire about a private dive guide, but in general dive groups are usually small.
