The misty hills, lush teakwood and sandalwood forests, and acres of tea and coffee plantations of Kodagu are, in a word, stunning. Also known as Coorg and dubbed "The Scotland of India," Kodagu is a postcard-perfect region of scattered villages and hamlets, which are the epitome of old-world charm. Kodagu is ideal for outdoor activities such as trekking, angling and white-water rafting, and major festivals like Keil Poldu (worship of weapons), Cauvery Shankaramana (return of the river goddess) and the Huttari (harvest) festival are a huge draw.

Known as both the "Garden City" and "The Silicon Valley of India," Bangalore (officially "Bengaluru") is a techie’s paradise, boasting the highest concentration of IT companies in the country. When you’re done geeking out, there are plenty of gardens, museums, natural features, palaces and temples to fill your dance card. Visit Vidhana Soudha, Cubbon Park and the Ulsoor Lake of Bangalore, well known for its beautiful locales and boating facilities. Bangalore is also a major centre of Indian classical music and dance, and of vivid, cutting-edge nightlife.

The people of Tamil Nadu consider providing food to others a service to humanity. Thus the service in the state capital, Chennai, is first-rate.

And don't forget to have a cup of full-bodied Tamil coffee, enhanced with chicory—no visit is complete without it.

Want a taste of being royal? Eat in Hyderabad, where culinary traditions have been passed down from the Nizam monarchy. Arabic, Turkish and Mughlai influences are easily recognisable. The city is famous for its rich, aromatic biryani made with lamb, chicken or vegetables and served with fragrant basmati rice. Satisfy your sweet tooth with double-ka-meetha, a bread pudding.

Mumbai (formerly known as Bombay), India, is famous for its chaotic streets. For bargains and people-watching, outdoor bazaars top the list of attractions. Popular waterfront destinations are Marine Drive, where visitors go to watch the sun set over the Arabian Sea, and the carnival-like Juhu Beach. More sightseeing options are the Gandhi Museum, in the leader's former home, and the cave temples of Elephanta Island. For tranquillity, Mumbai has many religious sites, lakes and parks.

Home to lively festivals and a vibrant artistic community, clamorous markets and packed temples, this city is crowded and polluted, but ultimately invigorating.

Laid out by British architect Edwin Lutyens, the Indian capital is a striking modern metropolis. A gracious contrast to Old Delhi's winding streets, the grand avenues and stately buildings of New Delhi are rich with history and culture, from Gandhi's Delhi home (and the site of his assassination) to the tomb of Humayun, a complex of Mughal buildings reminiscent of the Taj Mahal. Chaotic traffic is best left to the locals. Negotiate a good price for taxis or travel on the new Delhi Metro.

Bangkok is full of exquisitely decorated Buddhist temples—as you go from one to the next you’ll be continually blown away by the craftsmanship and elabourate details.

A visit to Pattaya is a wonderful way to explore the beaches along the Gulf of Thailand. Relaxed and family-friendly Jomtien Beach is a hot spot for watersports and seaside massages. The giant Buddha of Wat Khao Phra Bat keeps watch over the city, and the wooden Wang Boran Sanctuary of Truth pays homage to Buddhist and Hindu art and architecture. At night, tons of bars and strip clubs attract an adults-only crowd.

Singapore is known as a bustling metropolis that also happens to be one of the cleanest and safest cities of its size in the world. (Just make sure you heed the local laws—something like spitting in the street might merely be considered rude in your hometown, but here, it carries a severe penalty.) You'll find historic sites like the Thian Hock Keng temple, superlative shopping (including gargantuan malls) and numerous beaches.
