Sam Roi Yot National Park

A stunning coastal national park 60km south of Hua Hin, Sam Roi Yot ("Three Hundred Peaks") is famous for its dramatic limestone hills, caves, wetlands and beaches. Phraya Nakhon Cave — featuring a royal pavilion bathed in natural light — is one of Thailand's most photographed sites. A paradise for birdwatchers, with hundreds of species including the rare purple heron.
