A coastal national park south of Hua Hin, where limestone peaks rise out of marshes, beaches and mangroves. The star is Phraya Nakhon Cave, where sunlight falls through a hole in the roof onto a small pavilion built for a visit by King Chulalongkorn. It's an easy day trip if you're staying in Hua Hin.
