Beginner-friendly north Guam reef drift finishing near Gun Beach.
Fai Fai is a north Guam reef drift that is usually run by boat and finished toward Gun Beach, giving newer divers an easy look at Tumon's outer reef when the sea is settled. The route follows shallow coral structure with steady turtle and reef-fish traffic rather than a complicated navigation plan. It is best timed for calm weather because swell and surface movement make the beach side rockier and less forgiving once conditions build. In calm water, the same reef edge also works for confident snorkelers.

Best Season
Calmer periods with settled seas are the easiest window; spring and fall are the usual manta season.
Typical Conditions
Usually dived as an easy north-coast boat drift, with the most comfortable finishes and snorkels in calm seas.

Safety Notes
Plan Fai Fai for calm seas and treat the Gun Beach side conservatively when swell is running, because the shoreline gets rockier and less forgiving as surface movement builds.
Community notes to help plan your visit.
Scuba Diving
Most scuba dives are run as a gentle boat drift that follows the reef toward Gun Beach. The appeal is an easy moving dive with turtles and reef fish when the sea state is cooperative.
Snorkeling
In calm conditions the reef starts close enough to shore for a rewarding snorkel, but the beach side is rockier and more tide- and swell-sensitive than central Tumon.
