The wow factor in this atlas is high because a healthy reef in two metres of water outruns many deeper dives. Risk sits in the middle: sun, boats, current and panic, not decompression. Seasonality follows wind, monsoon and jellyfish more than a federation calendar. This chapter is a craft and site map. It is not a live snorkel briefing and not a ticket from PADI or SSI.
