Cha-am and Hua Hin are both closely associated with Thai royalty, and located on the Gulf of Thailand, some 3 hours southwest of Bangkok. These are quiet and relaxing seaside resorts, ideal for family vacations. Merely 15 miles apart, Cha-am in Phetchaburi and Hua Hin in Prachuap Khiri Khan enjoy a wealth of satellite attractions. Prominent among these are national parks and historic cities.
