About Secret Reef

Secret Reef is a deep reef, stepped reef, pinnacles dive in Channel between Gili Meno and Gili Air, with a working depth range of approximately 14–30 m. The site is known for gorgonian fans, snapper schools, sweetlips, trevally, and reef sharks. Conditions remain variable, so the route, maximum depth and suitability are confirmed by the local guide on the day.

Best months to dive

May–October often provides the clearest conditions, although the reefs are dived throughout the year when daily conditions permit.

Diving is available year-round when wind, swell and current permit. May–October often brings clearer dry-season water; wet-season visibility is more variable. Wildlife encounters are never guaranteed.

Dive tips

  • Follow the local guide’s site- and tide-specific briefing.
  • Agree a maximum depth within certification limits; the published site range is 14–30 m.
  • Maintain neutral buoyancy and avoid contact with coral, artificial structures and the seabed.
  • Stay with the guide on the selected reef step, monitor depth and no-decompression time, and deploy an SMB for the drifting boat pickup.
  • Treat wildlife encounters as possible, never guaranteed, and give animals space.

Underwater photography

Wide-angle equipment suits the reef structure and larger marine life. Set exposure before entering current, keep the rig streamlined and secured, and prioritise depth, gas, buoyancy and buddy contact over the photograph.
