North, Central or South Vietnam? The best region for your trip depends on how much time you have, what you want to see and when you plan to visit. North Vietnam is ideal for mountains, rice terraces, traditional culture and destinations such as Hanoi, Ninh Binh and Ha Long Bay. Central Vietnam is a great choice for beaches, ancient towns and historical sites, with Hoi An, Hue and Da Nang among the most popular destinations. South Vietnam offers a warmer climate, lively cities, the Mekong Delta and tropical islands such as Phu Quoc.
