China is not usually associated with beach holidays, but the island of Hainan, billed as ‘China’s Hawaii’, aims to challenge those preconceptions. It’s fair to say that there’s still a fair way to go, but the beaches around Sanya are pleasant enough, and the rapidly developing skyline is a sight in itself.

The port of Chan May is close to a number of central Vietnam's star attractions. Just to the north lies Hue and its crumbling Imperial Citadel, a UNESCO World Heritage Site, while to the south is the city of Da Nang, a major US airbase during the Vietnam War, and pretty Hoi An, a dreamy tropical haze of teetering merchant houses, bustling markets and Chinese temples.

Saigon, as it was known then, was the capital of the South during the Vietnam War, and American-style capitalism has been embraced more enthusiastically here than in the North, with a clutch of shining skyscrapers standing as testament to Vietnam’s surging economic growth.

Attracting everyone from budget backpackers to ostentatious oligarchs, Koh Samui is one of Thailand’s most popular islands. It’s no surprise, given the truly stunning beaches, but the more developed areas such as Chaweng have lost a lot of their charm, so head for the quieter south and west if you can.

Thailand’s sprawling capital is an assault on the senses, an invigorating blend of tradition and modernity. Soaring skyscrapers, air-conditioned shopping malls and an efficient public transport system combine with shimmering golden temples, ancient palaces, floating markets and at times gridlocked rush hour traffic.

Laid-back Langkawi boasts some of Malaysia’s finest beaches, and it’s a place where the traditional kampung (village) way of life survives in spite of the island’s development as a tourist destination. It’s also a popular spot for snorkelling and scuba diving thanks to the clarity of the surrounding waters.

As well as a plethora of luxury resorts, Phuket has a charming old town replete with pretty Sino-Portuguese architecture, and acts as a jump-off point for exploring nearby islands and coastline.

The beaches, spectacular volcanic scenery and lush green rice terraces lend Bali a natural beauty that seems to dovetail perfectly with the island’s distinct Hindu culture, which adorns the landscape with stunning temples.

Komodo Island is situated within an area of spectacular natural beauty, home to the famous Komodo dragon. The stunning beaches are tinged with pink thanks to the high concentration of red coral just offshore, and the waters draw intrepid divers from all over the world.

The historic port of Albany was the first European settlement in Western Australia, and the town still has plenty of photogenically faded colonial architecture. Albany sits on Princess Royal Harbour, one of the world’s best natural deep water harbours, and the surrounding coastline is spectacular.

Kangaroo Island is Australia’s third biggest island, situated to the south west of Adelaide. It’s a rural and underdeveloped place, with an abundance of wildlife and some spectacular scenery, such as the weird, weather-sculpted boulders of Flinders Chase National Park.

Residents of Adelaide still take pride in the fact that their city was freely settled rather than founded as a penal colony, and the city traditionally had a reputation as a stuffy and pious sort of place. Adelaide has moved on, however, and these days it’s a thriving cultural hub with a superb culinary scene.
