Chuuk Lagoon Wreck Liveaboard
Spend 7 nights on a liveaboard, focusing on Operation Hailstone wrecks like the Fujikawa Maru and Shinkoku Maru.
A specialized itinerary designed for experienced divers: board on Saturday, enjoy up to four dives daily for a week, explore major wrecks according to the captain's schedule, and leave one day for land exploration after disembarking. Liveaboard operators generally require an Advanced Open Water certification and around 50 logged dives. Wreck depths vary significantly; deep sites require deep or technical diving certifications. This route is not suitable for non-divers, who should look at island-hopping itineraries instead.
Diving is possible year-round, with the most stable conditions from December to April. Itineraries may be adjusted during the typhoon season.
