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.

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.

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.

Ho Chi Minh City (HCMC) is Vietnam at its most dizzying: a high-octane city of commerce and culture that has driven the country forward with its pulsating energy. A chaotic whirl, the city breathes life and vitality into all who settle here, and visitors cannot help but be hauled along for the ride.

This stupendous coastline of ravishing white sands and azure bays is Vietnam's premier destination for beach holidays.

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.

South of Hanoi, Ninh Binh province is blessed with natural beauty, cultural sights and the Cuc Phuong National Park. Highlights include boat trips amid karst landscapes at Tam Coc and the Unesco World Heritage-listed Trang An Grottoes.

Meo Vac is a small but charming district capital hemmed in by steep karst mountains and, like many towns in the northwest, it is steadily being settled by Vietnamese from elsewhere. The journey here along the spectacular Mai Pi Leng Pass, which winds for 22km from Dong Van, is the main attraction. The road has been cut into the side of a cliff with a view of rippling hills tumbling down to the distant waters of the Nho Que River far below. Right at the top of the pass is a lookout point where you can stop to take in the scenery.

Highlights of the Danang region include the city's impressive urban energy, the rapidly evolving beach scene to the east of the river, and more remote and spectacular coastal scenery of the nearby Son Tra Peninsula. Look forward to some of Vietnam's best seafood and street food. It's worth booking a walking tour with a local to best understand Danang.

Tra Vinh, one of the prettiest towns in the Mekong Delta, is a peaceful place to explore the region's little-touted Cambodian connection. Around 300,000 ethnic Khmer live in the surrounding province and the area is dotted with more than 140 Khmer pagodas. With wide boulevards shaded by lines of trees, the town itself is more symbolic of the French colonialist era, but get beyond the outskirts and you'll soon discover that Khmer culture is still alive and well in these parts of Vietnam. Tra Vinh also has a small but active Chinese community, one of the few such communities that remain in the Mekong Delta region.
