Business Visit to Hua Hin, Thailand in May 2017. This time traveled around city and night market. Hua Hin is a seaside resort on the Gulf of Thailand, in the southern Thai province of Prachuap Khiri Khan. Once a quiet fishing village, it grew into a fashionable escape for residents of Bangkok after the 1920s, when the Thai royal family built summer palaces here. Hua Hin Beach, popular for kitesurfing and other water sports, is the main stretch of sand, lined with high-end hotels and seafood shacks.
