Guam
Guam has some of the best dive sites in the world since there has been minimal tourist impact compared to other better known dive locations. Piti Bomb Holes is a tourist attraction allowing tourists to descend into an observatory where they can take in the beauty that has grown in a sinkhole. Divers can dive around this attraction and feed swarms of fish.
Guam waters maintain a temperature of 82-86 (28C) degrees year round with excellent visibility at most locations.
- The Fish Eye underwater observatory, located in a "Piti Bomb Hole". It is thought that the "Bomb Hole" was actually created by collapsed caves that have been filled with sea and sand.
- While many of the dive sites can be reached by land, some of these entry points require a long walk over coral or a long surface swim.
