The reef-safe sunscreen requirement
Oxybenzone and octinoxate (in many drugstore sunscreens) bleach coral in microscopic concentrations — 14,000 tonnes of sunscreen end up on reefs globally each year (NOAA estimate). Buy a mineral sunscreen with zinc oxide or titanium dioxide as the active ingredient. Brands that ship reef-safe formulas: Stream2Sea, Manda, Raw Elements, ThinkSport. We sell a few brands at the dive centre if you forget — but you'll want it before the boat ride, so buy before flying.
What we provide — so you can leave it at home
Full dive gear: BCD, regulator, mask, fins, 3 mm wetsuit, tank, weights — all included with every course and fun dive. Towels at the centre for between-dives. Fresh-water rinse station for your camera/GoPro. Lockers for your dry stuff during the boat. You can rent dive computers for 50,000 IDR per day if you don't own one (you don't need one for the Open Water — the instructor manages your no-deco time). Underwater camera rentals available too.
