The boat slips away from Ao Nang as late afternoon light gilds sheer limestone cliffs; salt smells of the Andaman press against your skin and the sea dares you to dive in. Over the next seven hours you’ll hop from coral-strewn snorkeling sites to a widening sandbar that links Tup, Mohr and Chicken Islands, watch the sun set behind Poda’s cliffs while a buffet waits, then wade into warm ink-black water to see bioluminescent plankton flare around your hands like captured stars.
