The seaside town of Hua Hin, meaning “Stone Head”, was named after the rocks at the north end of the powdery sand beach. Hua Hin became Thailand's first beach resort after a train line was laid in the 1920 to provide access from Bangkok and King Rama VII established his summer retreat in the area. With a 5 kilometer-long beach that features numerous activities and hosts an annual jazz festival, the laid back and hospitable town of Hua Hin continues to draw both tourists and Thais.
