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.
