Guam Blue Hole, Great Barrier Reef in Australia

The Guam Blue Hole is located about 100 ft. off the west coast of Guam an island in the Western Pacific Ocean. This rare blue hole is an open chasm that begins at 60 feet, opens to the sea at 130. The scuba divers can see along the reef top some fishes like dogtooth tuna and eagle rays with dolphins and pilot whales can also be found occasionally.

It is strictly bound for skilled divers. Because, the shore line of the Blue Hole is a cliff of almost 150 ft high, hence there is no beach entrance. It is only accessible via boat. Though, besides diving, Guam Blue Hole is a paradise for photography. Also, for Corals, one have to dive at Hap's Reef, located outside Apra harbor or Finger Reef, inside Apra Harbor, which has a wonderful accumulation of corals.
