It is situated within Chuuk State, part of Micronesia, and is renowned as one of the best wreck diving destinations in the world. Diving Chuuk Lagoon is a highlight of many recreational and technical divers' careers, and the wrecks can be explored from either a liveaboard or land-based resort.
Truk Lagoon scuba diving is best known for its 60+ World War II wrecks, which easily makes Chuuk Lagoon one of the world's best wreck diving destinations. Due to its strategic location, Truk Island used to be a Japanese Naval Base during WWII. Today the shipwrecks of Truk Lagoon offer a good amount of marine life, with many soft corals and schools of small fish. Some of the wrecks are quite deep, reaching 215 feet (65 meters), while others have parts of the superstructure as shallow as 40 feet (12 meters). This makes Truk Lagoon an excellent destination for all experience levels, from recreational to advanced technical divers.
Though known for its amazing wreck diving, Truk Lagoon is surrounded by a barrier reef. You can see corals of all shapes and colors, plus what is even more amazing, most of the wrecks are covered in soft coral. Even if wreck diving is not your favorite, it is full of beautiful coral and it is amazing to see tropical fish swimming around tanks, bicycles, trucks, torpedos, airplane parts, and much more.
The lagoon offers dive sites for every level of scuba diver. You can find shallower wrecks to dive at or there are also options for exploring deep inside various wrecks. Marine life enthusiasts will be captivated by all the marine life that the soft corals on wrecks have attracted. You can see plenty of macro objects like nudibranch and anemones or even larger animals like reef sharks. The dive conditions are great with warm waters all year round and very little current inside the lagoon that makes the dives relatively easy.
The name "Truk" is actually a corruption of the native name for this area, Chuuk, which is part of the Federated States of Micronesia. Many know it also by the name Chuuk Lagoon but for divers, it is more known as Truk Lagoon or Truk Island.
The diving season in Truk Lagoon lasts year-round as visibility is fairly consistent year-round and rain is intermittent. However, it's important to take note that therainy season lasts from April to December, and while thedry season lasts from December to April.
The wrecks of Truk Lagoon host beautiful soft corals and schools of small fish. There are reef sharks swimming by, but they can be hard to take photos of. However, numerous species of large jellyfish abound in Truk. While macro life may not be as abundant here as in other places nearby, there are various nudibranchs, anemones, porcelain crabs, shrimps, and small fish to photograph.

There are far too many wrecks to explore at Truck Lagoon, so here are some of the best dive sites in the area:
The San Francisco Maru (Depth 100 - 200 feet) - It is the most famous wreck because of its 3 tanks with guns on the deck, but it is also very deep, sitting at 170 ft (52 meters). Thus the wreck is only suitable for advanced divers that can see the tanks or technical divers who wish to go deeper. The wreck is not surrounded by a lot of marine life, but it has some amazing war artifacts.
The Fujikawa Maru (Depth 0 - 120 feet) -Is a favorite wreck to dive for many scuba divers as it is filled with fish and corals. The ship still has a gun perfectly intact and you can easily access the staterooms and baths.
Betty Bomber (Depth 50 - 60 feet) - A shallow wreck that is great for all levels of divers. The plane used to lit up when fired its guns which gave it the nickname "flying cigar". The wreck lies around 65 feet (19 m) but lost its nose, engines, and wingtip that still can be found around 325 feet (100 m) away from the wreck.
The I-169 "Shinohara" (Depth 85 - 130 feet) - The sunken submarine that accidentally flooded is now a wonderful dive site. You cannot enter the submarine but diving around is truly spectacular, plus it's a favorite spot for jellyfish and occasionally you can spot some turtles, rays, or sharks passing by.
