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.

The once sleepy backwater of Kompong Som, renamed after the former king Norodom Sihanouk, is the rising star of the Cambodian coast’s burgeoning tourist industry. Here you’ll find beautiful sandy beaches and a string of laid back islands that are still largely undeveloped.

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.

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.

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.

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.

Booming Shanghai has long been China’s most outward-looking, cosmopolitan city, as evidenced by the fascinating mixture of European and Asian architecture. The Bund, a riverfront promenade flanked by grand colonial era buildings, is the city's most famous thoroughfare, while the Pudong financial district lights up the city skyline at night with its futuristic towers.

Three days after Hiroshima was flattened by an atomic bomb, Nagasaki suffered the same horrifying fate. The reconstruction of both cities has been quite extraordinary; Nagasaki today is a vibrant, cosmopolitan place, with a fascinating history that goes back a lot further than 1945.

The friendly southern Japanese city of Kagoshima enjoys a balmy climate, and sits just across the bay from the very active Sakurajima volcano, which erupts so regularly that an ‘ash forecast’ is included in local weather reports.

Ishigaki is the most developed of the Yaeyama islands, an idyllic tropical archipelago located closer to Taiwan than mainland Japan. The offshore coral reefs make this a popular spot for diving and snorkelling, while the jungle interior offers some great hiking opportunities.
