A breathtaking cluster of granite islands, set in aquamarine seas around 15km directly offshore from Hoi An, the Cham Islands make a wonderful excursion. The islands were once closed to visitors and under close military supervision, but now day trips, diving or snorkelling the reefs, and even overnight stays, are possible.

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.

A popular weekend escape from HCMC, Vung Tau rocks at weekends when beach-starved locals and expats descend in numbers, but it is relatively quiet during the week. The city enjoys a spectacular location on a peninsula, with ocean on three sides; the light and sea air make it a refreshing break from sultry Saigon.

Welcome to an alternative reality populated by European royalty, film stars and the otherwise rich and secretive. For the average punter not able to afford an uber-luxurious hotel, this place doesn’t exist. Well, at least not before 2017, when the mother-of-all flashpacker retreats opened here on a private bay.

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.

The site of Vietnam’s most extensive Cham remains, My Son enjoys an enchanting setting in a lush jungle valley, overlooked by Cat’s Tooth Mountain (Hon Quap). The temples are in poor shape – only about 20 structures survive where at least 68 once stood – but the intimate nature of the site, surrounded by gurgling streams, is still enthralling.

Lang Co is an attractive island-like stretch of palm-shaded white sand, with a turquoise lagoon on one side and 10km of beachfront on the other. As a beach resort it's more geared to Vietnamese day trippers than Western travellers, but if the weather's nice the ocean is certainly inviting (if you stay away from the central section, which could be cleaner). High season is April to July. From late August to November rains are frequent, and from December to March it can get chilly.

Draped along the banks of the Hau Giang River (Bassac River), Chau Doc sees plenty of travelers washing through on the river route between Cambodia and Vietnam. A likeable little town with significant Chinese, Cham and Khmer communities, Chau Doc's cultural diversity – apparent in the mosques, temples, churches and nearby pilgrimage sites – makes it fascinating to explore even if you're not Cambodia-bound. Taking a boat trip to the Cham communities across the river or heading to nearby Sam Mountain and Tra Su Bird Sanctuary are other highlights, while the bustling market and intriguing waterfront provide fine backdrops to a few days of relaxation.

Ninh Binh is a good base for exploring quintessentially Vietnamese limestone scenery. Few Western tourists head here, but many Vietnamese flock to nearby sights, including the nation’s biggest pagoda and the Unesco World Heritage–listed Trang An grottoes.

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.
