Morning light slashes across the Gulf of Thailand as the speedboat cleaves open the water and the limestone towers of Ang Thong lift from the horizon like carved islands. On this full-day circuit visitors hop between emerald lagoons, snorkel reefs, kayak into sea caves, and climb a short ridge on Koh Wua Ta Lap for a panorama of the park’s scattered arches and bays.
