Across the Gulf of Thailand, Ang Thong National Marine Park awaits on a full-day big boat trip from Koh Samui, blending island sightseeing, beach time, snorkeling, hiking, kayaking, Emerald Lagoon, Thai lunch, and hotel transfer in one route.

After hotel pickup, head to the pier and cruise toward the 42-island archipelago. Relax on the outdoor deck, feel the sea breeze, and take in limestone cliffs, forested islands, caves, and open sea before the first stop.

Arrive at Ko Wua Ta Lap, the park’s main island, where you can swim near the beach, snorkel in clear water, relax on the sand, or visit Bua Bok Cave to see stalactites and stalagmites. For a more active moment, hike to Wua Ta Lap Viewpoint, also known as Pha Chan Charat, for a wide panorama over the islands and sea.

Enjoy Thai lunch on board before continuing to Ko Mae Ko for kayaking along limestone coastlines and cave routes. Then visit Emerald Lagoon, also known as Talay Nai, a hidden saltwater lake surrounded by limestone mountains and naturally linked to the sea.

After the final stop, cruise back after a full island escape packed with snorkeling, kayaking, sea caves, Emerald Lagoon, and sweeping views across Ang Thong’s 42 islands, with Koh Samui hotel transfer included.
