Just off the coast of Koh Samui, Ang Thong Marine Park is a cluster of 42 islands where limestone cliffs, hidden caves, and emerald lagoons create a breathtaking adventure. If you’re seeking a little more than just the beach, this protected paradise delivers unforgettable experiences.
Speedboat Tours
While there are plenty of things to do in Chaweng, going beyond the main beaches and heading to a national marine park offers an authentic encounter with Koh Samui’s natural beauty. The best way to explore Ang Thong is by speedboat, offering quick access to its many islands.
With excursions offered by resorts like Avani Chaweng Samui Resort, cruise along the turquoise waters and enjoy views of secluded bays.
Exploring Emerald Lake
One of the park’s most famous highlights is Emerald Lake. Known locally as Talay Nai, this mystical saltwater lagoon is situated within steep limestone walls. A short hike rewards visitors with stunning views and a surreal glimpse into this natural wonder.
Cave-Hopping Adventures
Ang Thong’s caves add mystery to the journey. The Lotus Cave, for instance, enchants with stalactites and serene chambers, while Bua Bok Cave reveals unique rock formations and ancient legends, making cave-hopping a must for explorers.
Snorkelling and Other Activities
Beyond caves and lagoons, the park offers colourful coral reefs perfect for snorkelling, kayaking through hidden inlets, and hiking trails with sweeping island views.
