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.

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.

Northwest Vietnam, with its rocky, cone-like mountains, high vistas and deep valleys, encompasses some of the most extreme geography in the country – if not all of Southeast Asia. Travelling to the more remote parts of the region takes time and effort, but those short on either can stick around Sapa, the surrounding hills of which are a microcosm of the region as a whole.

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.

With 307 species of bird, 133 species of mammal, 122 species of reptile and more than 2000 species of plant, Cuc Phuong National Park is one Vietnam’s most important protected areas.

With limestone outcrops amid serene rice paddies, Tam Coc is best appreciated on a languorous rowing-boat ride, with the soundtrack of the river lapping against the oars.

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.

Few parts of Vietnam stir the imagination with the lure of adventure quite like the highlands. The ribbon that is the Ho Chi Minh Hwy winds its scenic way past coffee plantations, pine-studded mountains, rice paddies with their wallowing buffalo, enormous reed-covered lakes and peaceful villages, laying down the challenge of a two-wheeled journey.

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.

Despite enjoying a stunning position on the cusp of Halong Bay, where its high-rise hotel developments dot the shoreline, most travelers opt to skip Halong City, preferring to spend a night out in the bay itself. As such, increased competition for a dwindling clientele means the budget hotel rates here are some of the cheapest in Vietnam.
