42 islands of untouched paradise — the must-do excursion from Koh Samui
The must-do excursion from Koh Samui! In a small group aboard our speed boat, this day trip will take you to Ang Thong National Park — around 50 minutes of navigation on the outward journey and another 50 minutes on the return.
The park comprises 42 islands with limestone monoliths declared a National Marine Park in 1980. It's a protected area housing fish, dolphins, whales, and monkeys.
Experience an exceptional day in this protected nature reserve, with white sand beaches, extraordinary viewpoints, an emerald lagoon, lush vegetation, snorkeling, as well as relaxing time on secluded beaches.
Discover the famous Talay Nai — a hidden saltwater lake surrounded by towering limestone cliffs, glowing emerald green.
Hike to the Wua Talap viewpoint for breathtaking panoramic views over the 42 islands, then relax on secluded white sand beaches.
Ang Thong is a fully protected marine park. Spot monkeys, tropical birds, coral fish and — with a bit of luck — dolphins or even migrating whales.
