The day begins before dawn on Khao Lak’s shoreline, boarding a speedy long-tail for the open Andaman Sea as the horizon lightens. Salt air pushes against the boat and the islands climb from the blue—steep granite boulders, white beaches and reefs that pulse with color. By the time the engine eases, you’re at Koh Miang and the water is calling: clear, warm, and brimming with fish that dart like living confetti.
