Facts about Angthong National Marine Park

Angthong National Marine park is an archipelago of 42 islands found in the Gulf of Thailand to the west of Koh Samui and Koh Phangan, best known as the setting for the Alex Garland novel “The Beach”.

Covering an area of 102km2, of which 82% is water, the park was established in November 1980 to protect an area which is famous for its natural beauty.

Weather at Angthong National Marine Park

The islands consist of limestone mountains, sitting between 10 and 400m above sea level, which also contain many caves created due to the ease with which limestone can be changed by weather conditions and chemicals.

Each island is different in shape and size, and many are named after their distinguishing features, such as “Sleeping Cow Island” and “Three Pillars Island”.

The majority of the islands are covered in 4 types of tropical forests. The larger islands are mainly covered in dry, evergreen forest and have a narrow strip of beach forest running around their edge.

Limestone forest covers the exposed cliff faces and the tops of the hills, where the soil is shallow, and mangrove forest can be found at sheltered spots where sandbars and mudflats have developed.

The islands are also home to the Lady’s Slipper Orchid, a species which is only found in the park.

Uninhabited islands in the Gulf of Thailand

With the exceptions of Koh Wua Ta Lap and Koh Phaluai, all of the islands within the park are uninhabited by people but the larger islands contain a limited number of animal species – 16 mammals, 50 bird, 14 reptile and 5 amphibian.

The mammals include long-tailed macaques, wild boar and smooth-coated otters whilst the birds include the white-bellied sea eagle, oriental pied hornbill and pacific reef heron.

Snorkeling Angthong National Marine Park

The waters within the park are better suited to snorkeling than diving as the average depth is just 10m and the visibility is poor due to sediment which flows from the Tapi River.

Coral development in the park is limited with just a narrow band around each island, close to their shores, particularly on the southwestern and northeastern sides. The northwestern sides have less coral, due to the effects of the monsoon, although sheltered spots still see good coral growth.

Marine Life at Angthong National Marine Park

The type of marine life within the park is dictated by the underwater geography. The coral reef areas contain a variety of animals, including butterfly fish, stingrays, angelfish, groupers and black tip sharks.

The areas with strong currents and murky water show significantly fewer species, predominantly inhabited by brown seaweeds, crabs and seaworms.

Coral cannot survive in the areas around the steep and rocky shorelines where the water is turbid, so these areas are dominated by sedentary marine life, such as clams, mussels, oysters and sea fans.

The evidence of these species can be seen on exposed rock surfaces in these areas.

Best Things to do in Angthong National Marine Park

There are a number of must do activities within the park depending on which island you are visiting. One of the main attractions of the park is the Pha Jun Jaras view point on Koh Wua La Tap (“Sleeping Cow Island”).

Hiking trails

It is accessible via a steep 500m trail which takes around 30-45 minutes to climb and can be slippery when it rains, so be sure to wear shoes with a good grip.

The path has a rope alongside it for support and there are viewpoints approximately every 100m along the trail. The view from the top provides a spectacular panorama of all the islands within the national park.

Once you have climbed the view point, you can make your way over to Bua Bok Cave. The trail to the cave is approximately 1km long and starts on the main beach.

This is a more difficult hike than the path up to the viewpoint and will definitely require good shoes, but once you arrive at the cave the path opens up to reveal a stunning display of stalactite and stalagmite formations.

On Koh Mae Ko, also known as “Mother Island”, you will find “Thale Nai” (Emerald Lake), a saltwater lake. The lake is connected to the ocean via underwater caves and surrounded by limestone cliffs.

No swimming in the lake

There is a trail up the cliffs which takes around 20 minutes to hike and will provide the best views of the lake. Be aware though that swimming in the lake is not permitted to protect the local wildlife.

Located to the East of Koh Mae Ko is Koh Sam Sao, or “Tripod Island”. With several beaches, some great coral, hiking trails and a camping site, this is another of the islands that is worth a visit.

On the north end of the island you will also find a dramatic, natural stone arch curving out into the sea that has been formed from the natural erosion of the limestone island.

Food and Eating in Angthong National Marine Park

There are limited options for food within the park and Koh Wua Ta Lap is home to the only restaurant, which is open until 10pm each night.

The restaurant provides local Thai cuisine at a very reasonable price, although be prepared to wait for your meal as the preparation is done very slowly.
