Guam, a U.S. island territory in Micronesia, offers a unique blend of vibrant coral reefs and profound historical wreck diving. Its most distinctive feature is the "twin wrecks" in Apra Harbor, where a WWI German freighter lies next to a WWII Japanese cargo ship, creating an unparalleled underwater museum. The island's diverse topography includes coral gardens, walls, and blue holes, all teeming with marine life. This accessibility to both world-class wrecks and healthy reefs from shore makes Guam a truly special destination for divers of all interests.
Diving in Guam is possible year-round thanks to its tropical climate and consistently warm waters. Visibility is generally excellent, often exceeding 30 meters (100 feet), particularly during the dry season. With over two dozen dive sites, many of which are easily accessible from the shore or via short boat rides, it caters to all skill levels from novice to technical divers. The combination of clear, warm water, incredible biodiversity, and significant historical sites provides a compelling reason for any diver to explore the underwater world of Guam.
