Cat Tien comprises an amazingly biodiverse area of lowland tropical rainforest. The 72,000-hectare park is one of the outstanding natural treasures in Vietnam, a true jungle, and the hiking, mountain biking and birdwatching here are the best in the south of the country. At weekends and public holidays it gets busy with domestic tourists – it's worth calling ahead to book the most popular excursions.
With its river setting and relatively traffic-free streets, relaxed Kon Tum makes a great stop for travelers intent on exploring the surrounding hill-tribe villages, of which there are 700 or so dotting the area – mostly Bahnar, but also Sedang and Jarai. This is a far better base than Pleiku for delving into indigenous culture, and there are a few intriguing sights in Kon Tum itself.
The spectacular karst limestone landscapes around Ninh Binh and Tam Coc are ideal for exploring by boat or bicycle, and there are stellar opportunities for caving and trekking amid the fast-developing travellers' scene of the Phong Nha-Ke Bang National Park. Dong Hoi, the coastal gateway to Phong Nha, also has an enjoyable low-key beach scene and good restaurants.

Practically obliterated during the American War, Vinh was rebuilt with East German aid – hence the brutalist concrete architecture dominating downtown. The only reasons to stop here are if you're a Ho Chi Minh devotee (he was born in a nearby village), or if you're heading to Laos.
The epicentre of the Mekong Delta, Can Tho is the largest city in the region and feels like a metropolis after a few days exploring the backwaters. As the political, economic, cultural and transportation centre of the Mekong Delta, it’s a buzzing town with a lively waterfront lined with sculpted gardens, an appealing blend of narrow backstreets and wide boulevards, and perhaps the greatest concentration of foreigners in the delta. It is also the perfect base for nearby floating markets, the major draw for tourists who come here to boat along the many canals and rivers leading out of town.
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.
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.
Wow, the vistas. This is Vietnam's big-sky country; a place of rippling mountains, cascading rice terraces and the winnowed-out karst topography for which the region is famed.
The bustling port city of Phan Thiet is traditionally known for its nuoc mam (fish sauce), producing millions of liters of the stuff per annum. There's not much to see in town, but the riverside fishing harbor is always chock-a-block with brightly-painted boats and there are sights nearby including the Ke Ga lighthouse and Ta Cu Mountain.
