Blue Hole - Guam

★★★★☆ (955)

Blue Hole is a very unusual dive on a natural limestone plateau. A vertical shaft begins at 60’ with a large “window“ opening at 125’. Drift dives are possible. You must be an experienced Deep diver to “shoot the hole“. Great vis and the 30 to 60’ plateau make this a popular site for all divers.

Green Sea Turtles hang out here and are seen by divers on most dives. Rays, Tuna, and other pelagic species frequent this site, so keep an eye out and enjoy!
