Why Divers Rate This Destination Highly

Truk Lagoon is the undisputed holy grail of wreck diving. The San Francisco Maru at 55 meters is still loaded with tanks and munitions from 1944, like a museum sealed for eighty years. The Fujikawa Maru's engine room, with intact telegraphs and portholes filtering blue light, is one of the most atmospheric dives on Earth. Truk demands experience — deep wrecks, overhead environments, long deco stops — making it strictly a technical divers' destination.
