The Mu Ko Ang Thong National Park is made up of 42 islands and covers a total area of 102 km² with 82% of marine area. 


The national park was previously closed from November until the end of December each year. However, due mainly to the period of Covid 19, which significantly decreased the number of visitors to the park for more than two years, the authorities have chosen not to close the park in December and November 2022.


Angthong National Marine Park is a protected area and is managed by the Royal Forest Department. The park is dedicated to the conservation of the marine ecosystem and the protection of the natural beauty of the islands.

The park is committed to sustainable tourism and encourages visitors to respect the environment and follow eco-friendly practices while visiting the islands.


The Royal Forest Department and the National Parks Division first established the Ang Thong Marine Park on 12 november 1980. A number of studies revealed the area’s ecological significance and the need to protect its distinctive marine environment, leading to the decision to create the park. Ang thong was declared a protected area in 1982.

The park’s name, « Ang Thong, » means « golden bassin » in Thai, and it is said to have been given the name because of the sparkling golden sands on the beaches of some of the islands.

If you can trek a bit, it's a must visit place. Enjoy the big boat tour. I would recommend NOT to take speed boad. Lo g boat has better experience, view relaxation option. And it is cheaper also.Long boat costs around 1400 Bath/person(if u wish to kayak 400bath extra), including hotel transfers to and fro. And speed boat costs 2100 Bath per person.

Ang Thong National Park has been one of the most beautiful places I have ever visited. The nature and the views are simply breathtaking. In addition to that, the whole one day trip was perfectly organized and we all had a lot of fun. If you come to Koh Samui you absolutely have to visit Ang Thong.

Superb experience. The cruise to Angthong Park was beautiful. We saw pink dolphins on the way there and back. The Emerald Lagoon was out of this world. It is definitely worth a visit! Thank you for the great experience 🙏
