Blue Hole

Depth Range 60 - 300+ ftWeather82.725.75 mphsse

The Blue Hole, one of Guam’s most popular divesites, is a natural shaft extending down into the reef. Soft and hard corals, sea whips, fish and eels can be seen inside the shaft.

The upper reef is at about 60 feet. From there, the shaft drops to 300+ feet. Gliding down the awe-in-spiring shaft can get even the most ex-perienced diver’s adrenaline up, so watch your descent rate and depth carefully.

The first opportunity to exit the shaft is at 127 feet. It is common to see large pelagic fish below and as you follow the wall on the outside of the Blue Hole you probably will see more.

Once out of the shaft, ascend to about 80 feet and follow the contour of the wall for a while. Then ascend to the 60′ reef flat where. There is a variety of hand-fed fish and several mounds covered with interesting corals and algae. Watch for large trigger fish and lots of schooling fish.
