Highlights of this area include the vibrant city of Danang, the former imperial capital of Hue, and the very popular but undeniably stunning historic port town of Hoi An. The best beach scenes are at An Bang near Hoi An and Lang Co near Danang, and for nature fans there is good hiking and birdwatching in Bach Ma National Park. Ancient Cham history is fascinating at My Son, and the compelling Demilitarised Zone (DMZ) showcases the poignant and tragic stories of the American War.

Nowhere in Vietnam is changing as fast as Danang. For decades it had a reputation as a quiet provincial town, but big changes are ongoing. Stroll along the Han riverfront and you'll find gleaming new modernist hotels, and apartments and restaurants are emerging. Spectacular bridges now span the river, and in the north of the city, the landmark new D-City is rising from the flatlands. Venture south and the entire Danang Beach strip is booming with hotel and resort developments.

Often referred to as the Ba Be Lakes, Ba Be National Park was established as a national park in 1992. The scenery here swoops from limestone mountains peaking at 1554m down into plunging valleys wrapped in dense evergreen forests, speckled with waterfalls and caves, with the lakes themselves dominating the very heart of the park.

There’s much more to northeast Vietnam than Halong Bay. The sinking limestone plateau, which gave birth to the bay’s spectacular islands, continues for some 100km to the Chinese border. The area immediately northeast of Halong Bay is part of Bai Tu Long National Park.

Fringed with white-sand beaches and with large tracts still cloaked in dense tropical jungle, Phu Quoc rapidly morphed from a sleepy island backwater to a must-visit beach escape for Western expats and sun-seeking tourists. Beyond the resorts lining Long Beach, rapid development beginning on the east coast and mega resorts in sight of Sao Beach, there's still ample room for exploration and escaping the sometimes littered waters. Dive the reefs, kayak in the bays, eat up the back-road kilometres on a motorbike or just lounge on the beach, followed by a massage and a fresh seafood dinner.

Northwest Vietnam, with its rocky, cone-like mountains, high vistas and deep valleys, encompasses some of the most extreme geography in the country – if not all of Southeast Asia. Travelling to the more remote parts of the region takes time and effort, but those short on either can stick around Sapa, the surrounding hills of which are a microcosm of the region as a whole.

This eponymous provincial capital isn't unpleasant; the climate is mild, and winter days can bring a chilly welcome relief from the heat when a thick fog clings to the banks of the Bang Giang River. But you'll most likely use the city as a base to explore rural Cao Bang province, one of the most beautiful regions in Vietnam.

Ha Giang is the final frontier in northern Vietnam, an amazing landscape of limestone pinnacles and granite outcrops. The far north of the province has some of the most spectacular scenery in the country – if not the region – and the trip between Yen Minh and Dong Van, and then across the Mai Pi Leng Pass to Meo Vac, is quite mind-blowing. Ha Giang should be one of the most popular destinations in this region, but its distance from just about everywhere else keeps visitor numbers at a low level.

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.
