A protected archipelago of 42 islands, with limestone cliffs, rainforest, hidden lagoons and coral reefs. It's best explored on a full-day private charter from Koh Samui.
Angthong National Marine Park, a stunning archipelago off the coast of Koh Samui, is a must-visit destination for nature lovers. Its 42 islands are covered in lush rainforest and rise into towering limestone mountains, with vibrant coral reefs below, making the park ideal for snorkelling, kayaking and hiking. Whether you’re exploring hidden lagoons or relaxing on pristine beaches, it offers an unforgettable day for all ages.
Two landmarks make the trip. On Koh Mae Ko, a short climb leads to Thale Nai, the Emerald Lake: a saltwater lagoon enclosed by cliffs and fed by the sea through underground channels. On Koh Wua Talab, home of the park headquarters, a steep trail climbs to a viewpoint over the whole archipelago. Between the two, there’s time to kayak along the cliffs, snorkel the reefs and stop on a beach that feels far from anywhere.
A private boat charter with Samui Explorer Boat Charters lets you plan the day around your own group of family and friends. You explore at your own pace, swim in crystal-clear water wherever it suits you, and our experienced captains and crew guide you to the best spots in the park.
Good to know: Angthong is a national park, so a park entry fee applies per person and is paid on the day [check: current fee and any seasonal closure]. Bring shoes with good grip for the viewpoint trail.
Book a private boat charter and discover Angthong National Marine Park at your own pace. It’s the ultimate Koh Samui day out.
