About Gun Beach
Gun Beach is a protected Tumon Bay shore reef with a shallow inner zone that opens toward a cable cut and deeper outer water. It works well as a relaxed snorkel and reef dive when conditions are calm, with healthy coral, sea fans, anemones, turtles, manta rays, and schools of reef fish giving the site plenty to look at. The outer edge can become rough when tide, surf, or current picks up, so the easy day and the risky day feel very different here.

Stay inside the reef on outgoing tide or rough water; the outer edge can run hard and the deeper cut should be treated with care.
Access Restrictions
Use the marked cut or channel for entry and avoid the outer reef when the sea is choppy or the tide is falling.
Legal Notes
Gun Beach sits within the Tumon Marine Preserve, so follow preserve rules and local shore-dive etiquette.
