Dive Guam's Blue Hole
Widely regarded as one of Guam's best dive sites, the Blue Hole is a natural limestone shaft that descends to 300 feet. Divers can expect to see hard and soft coral, sea whips, and trigger fish are frequently spotted; reef sharks and tuna are not uncommon, either.Only experienced deep sea divers are recommended to "shoot the hole," but dives around the upper plateau are safer for less experienced divers.
