Safety notes

Control depth on the descending slope, use low-impact finning over fine substrate and assess pebble entry conditions before carrying equipment into the water.

Dive tips

  • Follow the local guide’s site- and tide-specific briefing.
  • Agree a maximum depth within certification limits; the published site range is 5–40 m.
  • Maintain neutral buoyancy and avoid contact with coral, artificial structures and the seabed.
  • Control depth on the descending slope, use low-impact finning over fine substrate and assess pebble entry conditions before carrying equipment into the water.
  • 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.
