Guam has some of the best scuba diving sites in the world . . .

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.

What to see:
  • 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.
Need to know:
  • 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.
  • Many of the dive sites are accessed by land through US military bases.
  • No vaccination requirements for any international traveller.

Don't bother - Nothing to see.  Bell Marine Sport Co Ltd, Guam 1 Star Rating Added: 7th December 2008 by hesterstudio
This location is at the Sheraton Hotel. We went on 2 dives. Both sites offered nothing to view, except the Dive Master killing an octupus for his dinner. Not very enjoyable.
