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.

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.

Malaysia’s capital is a hot and humid cultural melting pot, defined by its distinctive Malay, Chinese and Indian communities. The dazzling Petronas Towers are KL’s most recognisable landmark, while at street level you’ll find temples and mosques, elegant colonial buildings and bustling markets.

The Malaysian island of Penang is a fascinating blend of East and West, far more than just a beach destination. Lovely Georgetown, a UNESCO World Heritage Site, is home to British colonial architecture, crumbling Chinese shophouses and incense-perfumed temples.

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. Koh Phing Pan, better known as James Bond Island, and Ko Phi Phi are breathtakingly beautiful, as are the limestone formations that surround Krabi.

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 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.

Mangalore, officially known as Mangaluru, sits on the coast of Karnataka, sandwiched between Goa and Kerala. The port was an important hub for trade with Arabia and Persia, and was later colonised by both the Portuguese and the British, leaving a rich architectural legacy of mosques, temples and churches.

The port of Mormugao is the gateway to the diminutive Indian state of Goa, famous for its golden sand beaches, hippie vibe and unique Portuguese heritage. Highlights include the beautiful colonial architecture of Old Goa, the charming capital, Panjim, and the fragrant spice farms of the interior.
