Spend a day island-hopping from Ao Nang aboard a speedboat or traditional longtail—snorkel coral gardens, walk a sandbar at low tide on Tup Island, and relax on powdery white beaches. This 6-hour trip balances easy swimming with dramatic limestone scenery.
More ways to explore the area's outdoor wonders
You step from the pier and the Andaman wind hits first — warm, saline, and insisting. The longtail and speedboats slice across cobalt water, islands rising as limestone ribs from the sea. Chicken Island’s head juts up close enough to inspect; Tup Island reveals its ephemeral sandbar at low tide like a borrowed bridge between two shores. Small coral gardens ripple beneath snorkel masks; sea and sky push and pull the day’s tempo.
