About Ang Thong National Marine Park

Ang Thong National Marine Park
 

Ang Thong National Marine Park is located in the Gulf of Thailand within Surat Thani Province. Established in 1980, it encompasses 42 uninhabited islands spread over approximately 102 square kilometers. The park is renowned for its striking limestone cliffs, hidden lagoons, white sandy beaches, and dense tropical jungles. The marine park is a protected sanctuary for diverse species of fish, coral reefs, seabirds, and other wildlife. Its crystal-clear waters provide excellent visibility for snorkeling and diving, while numerous caves and lagoons are accessible by kayak, offering immersive nature experiences. The park’s primary islands, such as Ko Wua Talap, Ko Mae Ko, and Ko Ta Pu (famous for its towering limestone spire known as James Bond Island’s ‘sister’), serve as focal points for hiking trails and panoramic viewpoints. Visitors can hike to scenic lookouts featuring breathtaking views of emerald bays and surrounding islands. While camping is restricted, day visits through organized tours from nearby Koh Samui and Koh Phangan are popular. This marine park is a vital conservation area balancing sustainable tourism with environmental protection. It offers an exceptional escape into nature where visitors can appreciate the beauty of Thailand’s coastal ecosystem and marine life.
