Vietnam

Around 40km west of Danang lies lush Ba Na. Originally established in 1919 by the French as a hill resort, the 200-odd old villas are now ruined, but the refreshingly cool weather and gorgeous countryside views make it a worthwhile trip from Danang.

Wow, the vistas. This is Vietnam's big-sky country; a place of rippling mountains, cascading rice terraces and the winnowed-out karst topography for which the region is famed.

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.

Steadily being transformed into a vast new city, Tuy Hoa is characterised by its vast plaza and multi-laned boulevards. It’s a possible overnight stop to break up a longer journey, especially for cyclists brave enough to tackle Hwy 1, but most visitors are just passing through.

Established as a hill station by the French colonialists in 1922, Sapa today is the tourism centre of the northwest.

Just 3km north of Hoi An, An Bang is one of Vietnam’s most happening and enjoyable beaches. At present there's a wonderful stretch of fine sand and an enormous horizon (with less of the serious erosion evident at Cua Dai), and with only the distant Cham Islands interrupting the seaside symmetry. Staying at the beach and visiting Hoi An on day trips is a good strategy for a relaxing visit to the area.

Practically obliterated during the American War, Vinh was rebuilt with East German aid – hence the brutalist concrete architecture dominating downtown. The only reasons to stop here are if you're a Ho Chi Minh devotee (he was born in a nearby village), or if you're heading to Laos.

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.

Designated a Unesco World Heritage Site in 2003, the remarkable Phong Nha-Ke Bang National Park contains the oldest karst mountains in Asia, formed approximately 400 million years ago. Riddled with hundreds of cave systems – many of extraordinary scale and length – and spectacular underground rivers, Phong Nha is a speleologists’ heaven on earth.

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.
