Palau’s waters conceal a compelling story—a tale of destruction and resilience, history and nature, past and present. Beneath the turquoise waves lie over 30 shipwrecks, remnants of World War II’s Pacific Theater, silently testifying to the chaos of battle and the passage of time. These relics, encrusted with coral and surrounded by marine life, are not just treasures for divers but living museums that narrate one of history’s most decisive periods.

Fish ’n Fins, Palau’s premier dive shop established in 1972, has become synonymous with exploring these wrecks. Over decades, they’ve uncovered the secrets of these sites, making them accessible to divers worldwide. Their annual WREXPEDITION event, now in its 14th year, is the ultimate opportunity for wreck enthusiasts to experience Palau’s underwater history. From June 4–11, 2025, participants will dive 14 wrecks, enjoy expert-led evening talks at the Barracuda Restaurant, and immerse themselves in the stories of Palau’s WWII past.

Palau in WWII - Operation Desecrate One

In March 1944, the serene islands of Palau became a theater of war. The U.S., determined to cripple Japan’s Pacific strongholds, launched Operation Desecrate One. This meticulously planned assault by Task Force 58 aimed to dismantle Japanese defenses, disrupt supply chains, and pave the way for Allied advances.

Over two days, American carrier-based aircraft unleashed an unrelenting barrage. Fighters strafed airfields, bombers targeted ships, and torpedo planes struck anchorages. The result was the sinking of over 60 ships, destruction of vital infrastructure, and the end of Japanese dominance in Palau. The remnants of this decisive operation now rest beneath the waves, transformed into vibrant reefs and wreck diving sites.

For Palau, these wrecks are more than relics of war. They symbolize the intersection of history and nature, offering a glimpse into the Pacific War’s intensity while supporting marine ecosystems. For divers, they are a portal to a world where time has stood still, surrounded by life’s resilience.

Exploring Palau’s Wrecks - Highlights of the WREXPEDITION

Each of Palau’s wrecks has a story, but a few stand out for their historical significance, accessibility, and allure to divers.

Amatsu Maru

The Amatsu Maru is Palau’s largest shipwreck and a highlight for wreck divers. This 10,567-ton oil tanker sank during Operation Desecrate One and now rests upright at depths of 80–135 feet in Malakal Anchorage. Its massive structure offers an unparalleled exploration experience.

Bow Section: Towering and adorned with black coral, this area provides stunning visibility and vibrant marine life.

Engine Room: A twisted, bomb-damaged area reveals the ship’s violent end.

Stern: Featuring an enormous propeller and remnants of a gun platform, the stern is a photographer’s dream.

Marine life flourishes on the wreck, with schools of fish weaving through the skeletal remains. The Amatsu Maru’s calm waters and historical significance make it a must-dive site for intermediate and experienced divers.

Iro Wreck

The Iro, a Japanese fleet supply vessel, is another iconic wreck. Anchored in Palau during WWII, it was heavily bombed in 1944, sinking to a depth of 60–120 feet. Its massive propeller and visible damage from bomb strikes are striking reminders of its wartime role.

Photogenic Stern: The propeller, untouched by coral growth, is an iconic feature.

Interior Exploration: The ship’s engine rooms and boiler spaces are accessible to experienced divers.

The Iro is both a historical artifact and a diver’s playground, offering thrilling penetration dives for seasoned explorers and external wonders for recreational divers.

Jake Seaplane

Not all wrecks are massive ships. The Jake Seaplane, a Japanese Aichi E13A-1 reconnaissance aircraft, rests at just 45 feet, making it ideal for snorkelers and beginner divers. Its shallow depth and excellent visibility reveal a wreck beautifully encrusted with coral.

Though less dramatic than its larger counterparts, the Jake Seaplane offers unique appeal:

Accessibility: Located just five minutes from Koror, it’s perfect for a quick dive or snorkel.

Vibrant Surroundings: The coral-covered plane attracts marine life, from octopus to colorful reef fish.

Its broken tail and bent wings tell a story of wartime chaos, blending history and marine beauty.

The WREXPEDITION is not just about diving; it’s about immersion—into history, camaraderie, and the unique underwater world of Palau. Over seven days, participants will dive three wrecks daily, guided by Fish ’n Fins’ expert team.
