Explore One of Thailand's Most Beautiful National Parks
The Ang Thong Marine Park day trip from Koh Samui is one of the most spectacular excursions in the Gulf of Thailand. This protected archipelago of 42 limestone islands offers an extraordinary mix of activities: snorkeling among vibrant tropical fish, kayaking through hidden sea caves, and hiking to breathtaking panoramic viewpoints.
At the heart of the park lies the legendary Emerald Lake (Talay Nai) on Koh Mae Koh — a stunning saltwater lagoon completely enclosed by cliffs. The tour also stops at Koh Wua Talap, where adventurous travellers can hike to one of the best viewpoints in all of Thailand.
