Between Gili Meno and Gili Air

Secret Reef

Flat on top — then the reef steps down, layer by layer, until the bottom disappears.

1430METRES

The reef that steps down

Secret Reef sits in the water between Gili Meno and Gili Air. You arrive on a flat coral top at around fourteen metres, which gives away nothing about what the site actually is.

Swim to the edge and the reef starts stepping down — terrace after terrace of coral, each one a little deeper and a little bluer, until the last one falls away and there is nothing below you but open water.

The terraces themselves are colourful and well covered, with gorgonian fans on the deeper steps and snapper schooling along the drops. The reason this is Ang's favourite is not a species; it is the edge.

Who can dive it

The top of the reef is already at fourteen metres and the whole dive is about following the steps down from there, so how far you get depends on your certification: eighteen metres on an Open Water card, thirty on Advanced. The crew sets the plan on the boat.

On most dives

  • Gorgonian fans on the deeper terraces

Ang's favourite
Ang has dived every site on this list more times than he can count, and this is the one he picks. Not for what lives on it — for the moment the last terrace drops away and the blue takes over.

Conditions across the Gilis

The same for every site on this list.

Water temperature
27–30 °C year-round — a 3 mm wetsuit is plenty
Visibility
10–35 m — clearest in the dry season, May to October
Boat ride
5–15 minutes from Gili Air
Group size
Maximum 4 divers per guide

Diving works all year here. April to October is the dry season and gives the clearest water, with September, October, May and June the sweet spot; July and August are the busiest. November to March brings plankton and less visibility, and with it a better chance of something big passing through.
