What It Feels Like

Guam delivers signature walls, photogenic macro at pinnacles, and historically significant wrecks. Boats from Cabras Marina reach Apra Harbor reefs in minutes and outer wall sites like Blue Hole and Shark's Pit along the Orote Peninsula. Operators such as Micronesia Divers Association and Guam Tropical Dive Station run daily charters and training, with nitrox widely available.
