2. Get a Glimpse of History at Truk Lagoon
Located in Micronesia, Truk Lagoon was once the main base of operations for the Japanese naval fleet during World War II. Then, a series of Allied bombing raids forced the Japanese to pull out quickly. Now, roughly 60 ships and more than 250 airplanes litter the sandy floor of Truk Lagoon, a sight that divers will never forget.
