History of the Ang Thong National Marine Park

Established in November 1980, Ang Thong Marine Park became Thailand’s 21st national park. Initially, the park was only accessible to researchers and environmentalists, without any facilities for visitors. However, as the words of its untouched beauty spread, the park gradually opened to the public and gained popularity. In the 1990s, more facilities and basic accommodations were built, allowing visitors to experience the islands’ nature more deeply. 

The park consists of 42 islands, most of which are located close to each other, offering a stunning panoramic view around the park. Each island differs in size and shape, and their names are often based on their distinct geographical features, for example, Sleeping Cow Island or Three Pillars Island. 

The various shapes of the islands were formed due to centuries of erosion, which also sculpted hidden caves and cliffs among the islands. Because of the alluring landscape, Ang Thong National Marine Park was established and protected by the government to preserve the significant, diverse ecosystems of dense forests and rich underwater life. 

One of the reasons why the park gained popularity was its appearance in the novel, The Beach by Alex Garland. The renowned natural beauty of the park attracts many backpackers to visit and search for the secret island as mentioned in the novel. Until today, Ang Thong National Marine Park has been on the bucket list among travelers around the world.
