Towering limestone pillars and tiny islets topped by forest rise from the emerald waters of the Gulf of Tonkin. Designated a World Heritage Site in 1994, Halong Bay's scatter of islands, dotted with wind- and wave-eroded grottoes, is a vision of ethereal beauty and, unsurprisingly, northern Vietnam's number one-tourism hub.

If the tenacious spirit of the Vietnamese can be symbolised by a place, few sites are more symbolic than Cu Chi. At first glance there is scant evidence today of the fighting and bombing that convulsed Cu Chi during the war. To see what went on, you have to dig deeper – underground.

Established as a hill station by the French colonialists in 1922, Sapa today is the tourism centre of the northwest.

Lao Cai is squeezed right next to the Vietnam–China border. Razed in the Chinese invasion of 1979, most of the buildings here are modern. The border crossing slammed shut during the 1979 war and only reopened in 1993. Now it’s a bustling spot fuelled by growing cross-border trade.

Beyond the urban buzz and excitement of Ho Chi Minh City, the attractions of the surrounding region include fascinating cultural and historical sights such as the Cu Chi tunnels and the Cao Dai Holy See temple at Tay Ninh. Also worth exploring is the Unesco-accredited area around Can Gio, especially the extensive mangrove forests that were an integral part of the Viet Cong resistance effort during the American War.

Plonked about midway between My Tho and Can Tho, Vinh Long is a major transit hub and the capital of the province. For travelers, it's a gateway to island life, Cai Be floating market, abundant orchards and rural homestays.

The geographic heart of the nation, central Vietnam is packed with historic sights and cultural interest, and blessed with ravishing beaches and outstanding national parks. Marvel at Hue and its Imperial Citadel, royal tombs and excellent street food. Savour the unique heritage grace of riverside jewel Hoi An, and tour the military sites of the Demilitarised Zone (DMZ). Check out Danang, fast emerging as one of the nation’s most dynamic cities. Also emerging as a must-visit destination is the extraordinary Phong Nha region, home to three gargantuan cave systems (including the world’s largest cave), and a fascinating war history concealed amid stunning scenery. Enjoy well-earned downtime on the golden sands of An Bang Beach or learn to cook central Vietnamese cuisine, the nation’s most complex. With improving highways, and upgraded international airports at Hue and Danang, access to this compelling and diverse part of Vietnam has never been easier.

With 307 species of bird, 133 species of mammal, 122 species of reptile and more than 2000 species of plant, Cuc Phuong National Park is one Vietnam’s most important protected areas.

Dalat is an alternative Vietnam: the weather is spring-like instead of tropical hot, the town is dotted with French-colonial villas rather than socialist architecture, and the surrounding farms cultivate strawberries, coffee and flowers instead of rice.

Isolated from the mainland, the Con Dao islands are one of Vietnam's star attractions. Long the preserve of political prisoners and undesirables, they now turn heads thanks to their striking natural beauty. Con Son, the largest of this chain of 15 islands and islets, is ringed with lovely beaches, coral reefs and scenic bays, and remains partially covered in tropical forests. In addition to hiking, diving and exploring deserted coastal roads there are excellent wildlife-watching opportunities, such as the black giant squirrel and endemic bow-fingered gecko.
