The Blue Hole is one of the best dives in Guam (if not the best). It is a limestone carved hole that has an opening at sixty feet. Once you get to the top and you peer into the shaft, you can see the opening which is right around 126 feet. The visibility of this dive is awesome, but sometimes there can be some heavy currents. Maine life varies. The time i went there, there were many different types of fish. I did see some Lion Fish, and even though i did not see one, they tell me there are several Moray Eels that are local residents to this area. It is one of those dives that if you do not get there early it will be really crowded with many tourist divers.
