Traditionally, Hué has been one of Vietnam's main cultural, religious and education centres. Sadly, the intriguing Forbidden Purple City was largely destroyed during the Vietnam War. About 15km (9mi) south of Hué are the splendid Royal Tombs, of the Nguyen emperors.
Thien Mu Pagoda is one of the most famous buildings in Vietnam. The remains of the huge moated citadel, constructed by Emperor Gia Long, contain many interesting sights, such as the Ngo Mon Gate, Nine Holy Cannons, the Palace of Supreme Harmony, Nine Dynastic Urns and the Halls of the Mandarins.
The city of Dalat is the jewel of the southern Central Highlands region. The cool climate and park-like environment (dotted with Vietnamese-style kitsch) makes it one of the most delightful cities in Vietnam. Dalat is also a good base for trips into the surrounding highlands, which remain tranquil.
Emperor Bao Dai's Summer Palace is stuffed with interesting art and artefacts, and is well worth a look. Make sure you visit the Hang Nga Guesthouse & Art Gallery, nicknamed the Crazy House by locals. It's a counter-cultural gem created by artist and architect Mrs Dang Viet Nga (known as Hang Nga).
Ho Chi Minh City is the heart and soul of Vietnam. It's a bustling, dynamic and industrious centre, the largest city in the country, the economic capital and the cultural trendsetter. Yet within the teeming metropolis are the timeless traditions and beauty of an ancient culture.
This is a city that churns, ferments, bubbles and fumes. The streets, where much of the city's life takes place, are a jumble of street markets, shops, pavement cafes, stands-on-wheels and vendors selling wares spread out on sidewalks. It's impossible not to be infected by its exhilarating vibe.
Situated on the Gulf of Thailand, 8km (5mi) from the Cambodian border, the town of Ha Tien and its surrounding area are famous for their warm-water, white-sand beaches and fishing villages. The area is also noted for its seafood, black-pepper tree plantations and towering limestone formations.
The rock formations around the town support a network of caves, many of which have been turned into cave temples. Ha Tien is a 10-hour bus ride from Ho Chi Minh City. Because of uncleared land mines and booby traps, be wary of travelling off the beaten track near the Cambodian border.
Halong Bay, with its 3000 islands rising from the clear, emerald waters of the Gulf of Tonkin, is one of Vietnam's natural marvels. The islands are dotted with innumerable beaches and grottoes created by the wind and waves. Hang Dau Go is the most impressive grotto, a huge cave of three chambers.
Ha Long means 'where the dragon descended into the sea', and refers to a legend about a dragon who created the bay and islands with its flailing tail. There's a modern legendary creature, the Tarasque, said to haunt the area. Taking a tour of the bay is the main activity here; book one in Hanoi.
Dien Bien Phu, in the heart-shaped Muong Thanh Valley near the Lao border, is in one of the remotest parts of Vietnam. The valley is surrounded by steep, heavily forested hills and the area is inhabited by hill tribes, notably the Tai and H'mong.
Dien Bien Phu was the site of that rarest of Vietnamese military events, a battle that can be called truly decisive. It was here in 1954 that Viet Minh forces overran the beleaguered French garrison after a 57-day siege, ending any chance of France re-establishing colonial control of Indochina.
Hanoi has shaken off its once hostile attitude to travellers to become one of the most beguiling cities in Southeast Asia. It's slow-paced yet quick to charm, with a lovely landscape of lakes, shaded boulevards, verdant public parks and French-colonial architecture.
Hanoi personifies the spirit of historic Vietnam in the temples, monuments and pockets of ancient culture along the narrow streets of the Old Quarter, yet perfectly reflects the rapid changes sweeping the country as Hanoian yuppies sip cappucinos in roadside cafés and compare cell phones.
