Cairns is a buzzing tourist hub, gateway to the Great Barrier Reef and the Daintree Rainforest. A snorkelling trip out to the reef is the most obvious excursion to take here, but other options include riding the Skyrail cableway over the rainforest canopy or swimming in the croc-free saltwater lagoon.

More of a large town than a city, Darwin is less about what’s contained within the city limits and more about the huge expanse of wild landscape that’s outside it. Closer to Jakarta than Sydney, the city really does feel remote in its tropical perch.

Manila is a sprawling, chaotic conglomeration of soaring skyscrapers, faded colonial facades and ramshackle slums, and it’s certainly not everyone’s cup of tea. But if you have the stamina and an inquisitive nature, there is plenty to be enjoyed in the Philippines’ boisterous capital.

Hong Kong is a striking mix of ancient and modern, Chinese and British, and there is a lot more to the city than just skyscrapers and high finance. It's also a fantastic destination for foodies, a melting pot of culinary influences from around Asia and beyond.

Nha Trang is Vietnam’s premier beach destination, on a stunning bay dotted with idyllic islands. The main attraction is the laid back seaside atmosphere, but there are also a few noteworthy cultural sites, including the ancient Po Nagar Cham Towers, which were built between the 7th and 12th centuries.

Singapore’s heritage as an important trading post means that there is a real cultural mix, with four official languages: English, Chinese, Malay and Tamil. Step away from the gleaming towers and you’ll find yourself transported into another world amongst the intoxicating streets of Chinatown and Little India.

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.

Colombo may be a little chaotic, but there is plenty to recommend Sri Lanka's colourful capital. Faded colonial architecture and beautiful Buddhist temples hint at the city's considerable history, while the excellent restaurants, lively bars and characterful streets provide the perfect introduction to contemporary Sri Lankan culture.

Amazing high rise buildings, extensive air-conditioned shopping malls and extraordinary man-made tourist attractions (such as indoor ski-slopes) abound in the glamorous city of Dubai, home to some of the most glitzy and expensive hotels in the world.

Salalah is Oman’s second city, and the capital of the southern Dhofar region. Many visitors are surprised by the pleasant sub-tropical climate, which turns the city into an oasis of lush greenery during the ‘khareef’ (monsoon) season between June and September, and in many ways it’s more reminiscent of Zanzibar than Muscat.

Aqaba is Jordan’s principal beach resort, situated on the Red Sea coast close to the Israeli border. The main attraction in Aqaba itself is the incredible diving, though many visitors will choose to instead use the port as a jumping off point for the 'Rose City' of Petra and the desert landscapes of Wadi Rum.

The UNESCO World Heritage-listed centre of Naples rewards exploration, and in addition to the many cultural treasures waiting to be unearthed Neapolitans are rightly proud of their food; this is where you’ll find the best pizza in Italy. The city also acts as a gateway to the fascinating remains of Pompeii and Herculaneum, and the beautiful Amalfi coast.

Spread across steep hillsides that overlook the Rio Tejo, Lisbon’s colourful cityscape includes Gothic cathedrals, majestic monasteries and quaint museums. But for many the best times will be had wandering the narrow lanes of Lisbon’s lovely backstreets, with their great local food, wine and music.
