Ang Thong National Marine Park

About Ang Thong

Established as a marine national park in 1980, Mu Ko Ang Thong National Park is an archipelago of 42 islands covering 102 km² at the shore of the Surat Thai Province east of Ko Samui in the Gulf of Thailand. The park is registered as a Ramsar site by Ramsar Convention, an international treaty for recognition of important wetlands. Many sources refer to the islands as "Angthong" which is wrong, "Ang Thong" is the correct spelling and means "golden bassin".

The islands cover 18 km² of the park, the major ones are Ko Phaluai, Ko Wua Ta Lap, Ko Mae Ko, Ko Sam Sao, Ko Hin Dap, Ko Nai Phut and Ko Phai Luak. Highest peak is located on Ko Phaluai at 396 meters asl. Islands consist mainly of rugged and steep limestone hills, sinkholes, caves and inland marine lakes. There is one nomadic village at Ko Wua Ta Lap and one other at Ko Phaluai, other islands are uninhabited.

The nearest tourist destinations are Ko Samui (~30 km), Ko Pha Ngan (~35 km), Ko Tao (~55 km), Krabi (~240 km).

The headquarters and some basic facilities are located at Ko Wua Ta Lap.

Inspired by the novel "The Beach" by Alex Garland, Ang Thong became one of the prime destinations for backpackers in Thailand when the subsequent movie starring Leonardo Di Caprio came out. While the beach scenes from the movie were filmed on Phi Phi Islands in Krabi Province, some of the film sequences were filmen in Ang Thong Islands. The jump scene from the waterfall was filmed on Haew Suwat Waterfall in Khao Yai National Park.


The forests consist mainly of dry evergreen forest on bigger islands, also limestone forest and minor planted mangrove forest around the beaches and bays. Among the plants, Ang Thong Lady's Slipper Orchid (Paphiopedilum Ang Thong) is an endemic species found only in Mu Ko Ang Thong National Park.

The number of reported animal species from the park is limited; according park authorities 16 mammal, around 50 bird, 14 reptile and 5 amphibian species so far found in the islands but very likely most amphibian and reptile species reported from Ko Samu and Ko Phang Nga are also found in the park. Some of the mammal species on the islands are dusky leaf monkeys, long-tailed macaques, leopard cats, fishing cats, wild boar and smooth-coated otters. Some of the bird species are collared kingfishers, white-bellied sea eagles, brahminy kites, black bazas, oriental pied hornbills, eurasian woodcocks, pacific reef herons and common hill mynas.

The islands and the waters around are a popular destination for day-trips from the nearby islands for snorkelling, canoeing/kayaking, enjoying the beaches, hiking and more. There are many tour companies offering both group and private tours to the islands, these can easily be arranged on arrival to the island.

There are no canoes/kayaks to rent in the Islands, they must be arranged via a tour operator.

Canoeing in Ang Thong National Park

There are a few diving sites on the northern islands, more ideal for snorkeling. The average depth of the dive sites is around 10 meters with low visibility due to heavy sediment from the Tapi River on the mainland. Diving on one of the coral gardens may give an opportunity to see marine species like green sea turtles, hawksbill sea turtles and yellow-spotted trevallies. Best time for diving is February to October with best visibility around March to April.


Getting to the park

The only way to enter the park is through licensed tour operators. The recommended way of visiting the park is to hire a tour boat in a group and decide both schedule and destinations.
