Expert Guides and Geographic Resources for Khao Sam Roi Yot National Park, Thailand

Thailand's first coastal national park protecting limestone peaks, marshes, and a historic cave temple

Khao Sam Roi Yot National Park

Khao Sam Roi Yot National Park stands as a landmark in Thailand's conservation history as the first coastal national park established in the country. Located along the eastern shore of the Gulf of Thailand in Prachuap Khiri Khan Province, the park encompasses a remarkable diversity of landscapes within its 98 square kilometer boundary. The limestone hills that form the park's backbone represent a southern extension of the Tenasserim Hills, their jagged peaks creating a distinctive silhouette against the tropical sky. Between these hills lie extensive freshwater marshes, though significant portions have been converted to shrimp farms, highlighting ongoing tensions between conservation and development. The park's marine component includes coastal waters, two scenic beaches, and five uninhabited offshore islands that provide important habitat for seabirds and marine life. The park's accessibility from popular resort destinations like Hua Hin makes it a frequently visited protected area, with approximately 165,000 annual visitors exploring its trails, beaches, and caves. Beyond its natural significance, the park holds archaeological importance following the 2020 discovery of 3,000-year-old cave paintings in unmapped caverns within the limestone formations.
