Getting here

You can reserve your tour in any travel agency on Koh Samui, Koh Phangan or Koh Tao and you might choose to go to the marine park either by a speed boat or with a slower tour boat.


What to do?

Swim and snorkel surrounded by amazing limestone mountain islands in turquoise water. Or/and go on a Kayak trip and eat a well deserved dinner afterwards on a beautiful beach. Many tour operators include meals and refreshments in their tour package.


When to go?

It is usually ok to go here at any time of the year as the temperature is high year round on the islands of the Suratthani province. The monsoon or rain season is normally occurring from September until November, but usually there are many days with sunshine and blue sky in this period as well.


Islands and Beaches

Mu Koh Angthong became a national park in 1980. It consists of 42 islands of which Koh Wua Talap (the island of the sleeping cow) is the largest one.

There is a nice beach with white sand on the island of Ao Kha and you will also find a small national park office and a camping site here.

North of this island you will find Koh Mae Koh. On this island there is a beautiful inner sea named Talay Nai. It is about seven meters deep and has a few viewpoints. It is worth visiting even if you'll have to walk (and sometimes almost climb) for some time to get there. There are also two beaches on this island suitable for swimming: Ao Na Thap and Ao Tham Rang.

Other examples of islands situated here are Koh Sam Sao (North of Koh Mae Koh with a few pleasant beaches) as well as Koh Prayad, Koh Hin Dap and Koh Kha further North.


Be gentle with Nature

Please remember to treat the nature, sea and wildlife with respect in the Angthong National Marine Park. Please throw bottles and other waste in a garbage can to protect the nature and the animals. Please do not bring any corals or shells from the marine park. They belong to the nature.

Let our future generations enjoy these islands as well
