Slip through Koh Muk’s narrow tunnel to a hidden emerald lagoon, then hop between Kradan, Waen and Chueak islands to snorkel coral gardens and relax on white sand. This 6–7 hour speedboat tour pairs dramatic karst scenery with hands-on snorkeling for a compact Andaman day out.

The speedboat lifts on the Andaman’s swell and, within an hour, limestone towers rise like old sentries. You glide toward a narrow slit in Koh Muk’s cliff — the entrance to Emerald Cave — and the sea seems to hold its breath. Slip through the tunnel and a hidden lagoon opens: emerald water enclosed by sheer rock and dappled light that feels removed from time.
