The case for it
Why dive here
- Submerged seamount rising from about 75m to within 3-4m of the surface, in open water north of Gili Lawa
- Whitetip and grey reef sharks patrol daily; giant trevally, dogtooth tuna and mackerel hunt through the water column
- Reef hook dive on the current-facing side; 20-30m+ visibility in the dry season
Check before booking
What may rule it out
- Advanced open water certification is the stated minimum.
