Ko Samui: Ang Thong Marine National Park

The Ang Thong Marine National Park (Mu Ko Ang Thong National Park) is located in south-eastern Thailand and consists of 42 islands of limestone located just west of the island of Ko Samui, the park covers an area of 102 km².

The main islands that are part of the park are those of Phaluai, Mae Ko, Wua Talap, Sam Sao, Hin Dap, Nai Phut and Phai Luak. The islands are composed of limestone, are covered with forest and rising up to 400 meters high, there are some wetlands, such as the lake of the island of Mae Ko, many caves, such as Bua Bok Cave in Wua Talap island, and cliffs where nesting seabirds.

The park is famous for its natural beauty, the beautiful beaches of fine white sand, wildlife and lush vegetation, among the most popular activities are canoeing, snorkeling and hiking.

On the island of Wua Talap, where are the offices of the park and the visitor center, you can see the entire archipelago from above, following a trail that leads up to a lookout point located on top of the mountain.

The seabed of the park are quite low, never more than 10 meters deep, the water around the islands is sometimes cloudy due to the sediments carried by the rivers of the nearby mainland, so the development of coral reefs in the islands is not large, despite this, the place is very popular among those who love snorkeling.


The park can be visited from Ko Samui through a daily taxi-boat (tour boat) that connects Ko Samui with the Mu Ko Ang Thong National Park (the distance is 35 km).

During the monsoon, between November and December, the National Park remains closed due to wind and rough seas that make dangerous to navigate to the islands.
