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.

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.

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.

The ‘rice bowl’ of Vietnam, the delta is carpeted in a dizzying variety of greens. It's a water world that moves to the rhythms of the mighty Mekong, where boats, houses and markets float upon the innumerable rivers, canals and streams that criss-cross the landscape like arteries.

Towering limestone pillars and tiny islets topped by forest rise from the emerald waters of the Gulf of Tonkin. Designated a World Heritage Site in 1994, Halong Bay's scatter of islands, dotted with wind- and wave-eroded grottoes, is a vision of ethereal beauty and, unsurprisingly, northern Vietnam's number one-tourism hub.

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.

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.

Dong Hoi is a pleasantly untouristed port and seaside town. It enjoys an attractive location, clinging to the banks of the Nhat Le River, and has beaches to the north and south. Recently established air links to Haiphong (for Halong Bay and Cat Ba Island) and the northern Thai city of Chiang Mai promise to significantly increase the city's appeal as a destination. Dong Hoi also has excellent transport links to the Phong Nha region.

Once upon a time, Mui Ne was an isolated stretch of shoreline where pioneering travellers camped on the sand. Times have changed and it's now a string of beach resorts, which have fused into one long coastal strip. These resorts are, for the most part, mercifully low-rise and set amid pretty gardens by the sea. The original fishing village is still here, but tourists outnumber locals these days. There are a handful of luxury hotels (and a smattering of cheap guesthouses) but Mui Ne is mainly a midrange resort.
