Do not stand on the shallow plateau, maintain separation from resting sharks and turtles, and follow the planned side of the submerged island.

Dive tips

  • Follow the local guide’s site- and tide-specific briefing.
  • Agree a maximum depth within certification limits; the published site range is 5–30 m.
  • Maintain neutral buoyancy and avoid contact with coral, artificial structures and the seabed.
  • Do not stand on the shallow plateau, maintain separation from resting sharks and turtles, and follow the planned side of the submerged island.
  • Treat wildlife encounters as possible, never guaranteed, and give animals space.

Underwater photography

A flexible setup works best: use a macro lens for small subjects on sand, rubble and coral, or wide angle for the broader reef structure. Maintain stable trim, avoid stirring sediment and never move or touch wildlife for a photograph.
