Book on moonless nights
Bioluminescence is brightest around a new moon—check lunar calendars and reserve accordingly.
Wear biodegradable sunscreen
Oils and common sunscreens can harm the lagoon—use reef-safe products and avoid applying before getting in the water.
Bring a red-filter headlamp
A red light preserves night vision and won’t wash out the bioluminescence; keep white lights off while on the water.
