The port of Kochi, commonly known as Cochin, occupies a strategic location on India’s Malabar Coast, and its history as a trading hub is reflected in the blend of European, Chinese and Arabian influences. It’s also the gateway to the idyllic Kerala Backwaters, which are best appreciated on a houseboat cruise.

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.

The little island of Pulau Weh is situated just off the northwest tip of Sumatra, and the main city, Sabang, was an important transit hub during the colonial era thanks to its strategic location at the entry to the Malacca Strait. It’s a great destination for snorkelling and diving, with coral reefs rich in fish species.

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.

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.

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.

Almost 2,000 limestone islands and karst formations are scattered across the remarkable World Heritage Site of Ha Long Bay, said to have been created when a dragon fell to earth. A cruise on a small junk boat is the best way to see the many islands and caves, and it's also a great place to explore by sea kayak.
