There is only one, long beach: Hua Hin Beach (ชายหาดหัวหิน Hat Hua Hin). This runs from the Hilton Hotel six kilometres south to a headland where a Buddhist temple clings to the rocks. Fine white sand, resort hotels and many water sports opportunities lend the resort its distinctive ambiance. At the south end of town, the hill of Khao Takiab interrupts the beach. On the other side is a lovely swimming beach with a view of Khao Takiab's south face. Just a little further on, Suan Son Beach is owned by the Thai army but is open to the public. Notable for the tropical sea pines lining the shore. A little south of the Marriott, watch for tiny sand crabs digging industriously, leaving odd patterns of tiny sand clods around their beach front property.
Parts of the beach closer to the town may have greenish water, in this case continue walking down the beach where the water appears cleaner. There is an ample supply of deck chairs along the beach, although many places charge around 100 baht for their hire. Deck chairs that are part of a beachside cafe may be free, on the assumption that you will buy food or drink.
