A seven-hour semi-private speedboat tour from Ao Nang that combines snorkeling at Poda, Tup and Chicken islands with a sunset at Phranang Beach and a guided night swim to see bioluminescent plankton. Small groups (max 12) and included transfers make this an accessible evening adventure.
More ways to explore the area's outdoor wonders
The sun tilts low over limestone towers as the speedboat slips away from Ao Nang; spray smells of salt and citrus, and the distant karsts cut the horizon into dramatic silhouettes. You drop anchor at Poda’s broad white shelf, walk the quiet lee of the island, and push into warm water thick with reef life. Later, the boat threads the shallow sandbar between Tup and Chicken Island, where the tide reveals a walkway that briefly turns three islands into one.

History
Krabi’s dramatic limestone karsts rose from ancient seabeds; the coastline has long been home to fishing communities and the sea-nomadic Moken people, whose knowledge of currents and reefs shaped local maritime culture.
Conservation
Use reef-safe sunscreen, avoid standing on or touching coral, and follow guides’ instructions—small-group tours reduce crowding and help limit pressure on fragile sites.
