Ang Thong National Marine Park
Offshore west of Koh Samui, Thailand
Ang Thong gives a Samui holiday its grandest change of scale: steep limestone islands, sheltered shores and a saltwater lake enclosed by cliffs. Choose a guided boat outing that leaves room for kayaking and time ashore, rather than treating every stop as a photograph. The climb to the Wua Ta Lap viewpoint is strenuous, so discuss alternatives before departure. It is a rewarding choice for travellers who want landscape and movement between quieter resort days.
