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.

Set in an idyllic valley, hemmed in by hills, the Mai Chau area is a world away from Hanoi's hustle. The small town of Mai Chau itself is unappealing, but just outside the patchwork of rice fields rolls out, speckled by tiny Thai villages where visitors doss down for the night in traditional stilt houses and wake up to a rural soundtrack defined by gurgling irrigation streams and birdsong.

The high-rise, high-energy beach resort of Nha Trang enjoys a stunning setting: it's ringed by a necklace of hills, with a turquoise bay dotted with tropical islands.

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.

Heading east of Hoi An, new housing and hotels mix with older rice paddies, and the riverbank meanders for around 5km to sandy beaches. This palm-fringed coastline extends north to Danang, and despite the development, there are still a few quieter stretches; it's a good area to explore independently on two wheels.

Rugged, craggy and jungle-clad Cat Ba, the largest island in Halong Bay, has experienced a tourism surge in recent years. The central hub of Cat Ba Town is now framed by a chain of low-rise concrete hotels along its once-lovely bay, but the rest of the island is largely untouched and as wild as ever. With idyllic Lan Ha Bay just offshore, you'll soon overlook Cat Ba Town's overdevelopment.

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.

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.

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.
