Tay Ninh town, the capital of Tay Ninh province, serves as the headquarters of one of Vietnam’s most intriguing indigenous religions, Cao Daism. The Cao Dai Great Temple at the sect’s Holy See is one of Asia's most unusual and astonishing structures. Built between 1933 and 1955, the temple is a rococo extravaganza blending the dissonant architectural motifs of a French church, a Chinese temple and an Islamic mosque.

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.

This stupendous coastline of ravishing white sands and azure bays is Vietnam's premier destination for beach holidays.

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.

A large, prosperous coastal city, Quy Nhon (pronounced ‘hwee ngon’) boasts a terrific beach-blessed shoreline and grand boulevards. Its seaside appeal and tidy, litter-free streets make it the kind of place that affluent Vietnamese couples choose to retire to, spending their final days ocean-gazing and promenade-walking.

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 ‘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.

Buon Ma Thuot can trace its origins back to a simple rural settlement: the Ede name translates as ‘Thuot’s father’s village’. But Buon Ma Thuot (pronounced ‘boon me tote’) has long outgrown its rustic origins and is now a thoroughly modern, affluent city.

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.

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.
