Truk Lagoon map

Truk Lagoon, also known as Chuuk Lagoon, is located in the Pacific Ocean, about 1,000 miles northeast of Papua New Guinea. The lagoon is surrounded by a coral reef and contains more than 60 shipwrecks, which are the remains of Japanese naval vessels and aircrafts that were sunk by the US military during World War II.

Truk Lagoon’s history as a Japanese stronghold during World War II, combined with the eerie atmosphere of the sunken ships, has made it a fascinating and unique destination for history buffs and adventure-seekers alike. However, due to the depth and complexity of many of the wrecks, diving in Truk Lagoon requires advanced diving skills and certifications.

What prior travelers say


“Our first trip with Diventures was spectacular. They handled all of the boring parts of travel and left the fun parts to us. I truly felt that they went above what was expected in resolving the unexpected. The dives themselves were incredible, with a professional local team responsible for doing much of the heavy lifting. This left us to focus on the dive experience itself.”
