Explore South Guam

Diving in South Guam is a truly unique experience, offering a diverse array of underwater environments that cater to both beginners and seasoned divers. Unlike North Guam, South Guam's volcanic topography creates breathtaking dive sites with steep drop-offs, mysterious caves, and expansive caverns. One of the most renowned sites is the Blue Hole, where experienced divers can descend to impressive depths of 90 meters/295 feet and "shoot the hole" through an exhilarating exit at 40 meters/131 feet. The region is also known for its protected coves and bays, making shore diving accessible and providing a sheltered oasis for divers seeking tranquility.

South Guam is a treasure trove of marine life, where divers can encounter an array of fascinating creatures. The Shark Pit, located south of Blue Hole, is a remarkable site filled with historical artifacts including tanks and trucks, and teeming with sharks and even pilot whales. Adventurous divers will find 11 Mile Reef irresistible, with its strong currents attracting massive barracudas, turtles, and a host of large pelagic fish. Just off the coast, Cocos Island offers thrilling wall and drift dives amidst schools of dolphins and sharks, making it a must-visit for those seeking adrenaline-fueled encounters. South Guam's vibrant marine life and dynamic dive environments make it a standout destination for divers worldwide, promising unforgettable underwater adventures.
