Odyssey Adventures offers 7 day trips exploring the many wrecks of Truk Lagoon.
Over a 2 day period from February 17th – 18th 1944 the United States Navy launched an attack on the Imperial Japanese Navy. The Japanese had been using Truk as an anchorage for its large Combined Fleet. Often referred to as the “Gibraltar of the Pacific” or compared with Pearl Harbor, the location of Truk made it a prime shipping hub of aircraft and armaments from Japan to the Japanese “Southern resources area”
Over the two days of Operation Hailstone it is estimated that 250 Japanese warplanes and pilots were destroyed, about 40 ships- 2 light cruisers, 4 destroyers, 9 auxiliary ships and about 2 dozen cargo vessels were sunk. Its estimated about 4500 Japanese Soldiers lost their lives in the attack.
Considerable damage was done to the many island bases, including the dockyards, communications centers, supply dumps and the submarine base. After the operation Truk was effectively isolated for the rest of the war.
Two follow up attacks occurred in April and June of 44′ which brought the total to over 70 ships and 400 airplanes destroyed.
Today Truk Lagoon is massive underwater museum full of history from 1944. Scuba Divers from all over the world come to this small island to see and experience the history for themselves. Others are still working to identify some of the wrecks nearly 80 years on.

Although no two days with Odyssey Adventures will be the same a typical day begins at 7:00 with a hot breakfast followed by a dive briefing at 7:45. You'll have the morning to do 2 dives on the site before we move to the next site during lunch. After lunch 2 more dives are offered or you can relax on one of the sundecks or in your stateroom. Dinner is usually served around 6:30 and if you'd like you can do a night dive afterward. Often you'll find other guests hanging out in the entertainment lounge watching a movie or checking out the footage they got on the day's dives.
One of the best parts about diving aboard Odyssey is that you're not required to dive at a specific time. It is not unusual for you and your buddy to be the only divers on a 500' wreck. For photographers, this offers more opportunities to shoot those popular scenes without having to wait for others to move out of the way.
Diving in Truk Lagoon is an adventure you will never forget. WWII wrecks are scattered across 77 square miles. The wrecks are covered with life. There are over 300 varieties of hard and soft corals. On the outer reef, you’ll find mountains of coral that stretch as far as the eye can see, and drops off into the abyss. Here it is not unusual to see pelagic sharks.
The water temperature ranges from 82 to 84 degrees Fahrenheit. Visibility ranges from 30′ to 100′ depending on where you are in the lagoon and there is little current.
