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.
