Twin Rocks
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily — treat everything here as planning ranges.
Twin Rocks is the proof of what a small, well-guarded sanctuary can do. Two boulder heads a short swim apart rise from 15 m of sand, packed so densely with life that new divers assume it is normal: carpets of anemones boiling with clownfish, jacks and snapper in rotating schools, batfish escorts, giant clams settled between coral heads, and green turtles that graze through unbothered. Fish feeding was stamped out years ago, yet the residents never lost their boldness. It works equally as a first sanctuary dive, a relaxed afternoon, or a slow macro lap for photographers.
The moment you come for: Anemone cities, confiding schools, turtles at sanctuary ease
Topography: Two coral-crowned boulders on a sandy slope
Current: Occasionally a light current along the slope; easily managed.
Entry: Buoyed sanctuary a few minutes by banca from most resorts; no anchoring inside.
Know before you splash
Hazards: Weekend diver traffic; titan triggerfish territory in nesting season.
Conservation: A municipal marine sanctuary with per-dive fees; the density of life here depends on everyone keeping hands off.
