Diving in South Guam
South Guam has more dive sites than North Guam, offering different experiences for beginners and advanced divers. The topography of North Guam is mostly limestone, while the south is volcanic based, causing steep drop-offs, caves, and caverns. Protected coves and bays make shore diving in South Guam an easy option. Keep in mind that currents can be stronger in this region, so this place is better for more experienced divers. The best way to arrive at most of the dive sites is by boat. The most famous dive site is called Blue Hole, and it’s located toward the central area; Blue Hole plummets down to 90 meters (295 feet) deep, and it has an exit so that experienced divers can “shoot the hole” at 40 meters (131 feet). South of the Blue Hole, you will find Shark Pit, which is home to large tanks, trucks, and trailers, and is filled with sharks and pilot whales. If you are an experienced diver, make sure you include a visit to 11 Mile Reef; this place has strong currents, and massive barracudas, turtles, sharks, and other large pelagic fish. Another important dive site, filled with dramatic drift dives, spectacular wall dives, and big pelagic life, is Cocos Island; this is an uninhabited island famous among divers for its dolphin and shark encounters.
