Dive tips

  • Follow the local guide’s site- and tide-specific briefing.
  • Agree a maximum depth within certification limits; the published site range is 4–35 m.
  • Maintain neutral buoyancy and avoid contact with coral, artificial structures and the seabed.
  • Use a slow search pattern, keep fins above sand and algae, and never handle or reposition small subjects.
  • Treat wildlife encounters as possible, never guaranteed, and give animals space.

Underwater photography

Use a macro lens, focus light and patient search pattern. Keep fins elevated over sand or rubble, approach subjects slowly and never touch, reposition or crowd marine life. Night photographers should agree light and buddy signals before entry.
