If you have time to explore Chennai (formerly Madras), this 284-sq-mi (400-sq-km) conglomerate of urban villages and diverse neighborhoods making up Tamil Nadu's capital will pleasantly surprise you. Its role is as keeper of South Indian artistic, religious and culinary traditions.

With mountain adventures beckoning from all directions, Manali is a year-round magnet. Backpackers are well catered for in parts of Vashisht and Old Manai where numerous agents offer trekking, climbing, rafting and skiing according to season. Meanwhile, so many Indian families and honeymooners come for a first taste of snow that greater Manali now has an estimated 800 to 1000 hotels and guesthouses. Tight-packed resort buildings already fill the town center and are now steadily devouring former orchard terraces as far south as once-rustic Prini village. But while the whole area gets jam-packed in season (mid-April to mid-July, mid-September to mid-October, and over Christmas–New Year), it doesn't take too much effort to get off the main tourist trail. And in November, clear skies plus slashed prices make Manali a bargain – if you can handle the cold and the closure of some restaurants.

India’s third-largest city is a daily festival of human existence, simultaneously noble and squalid, cultured and desperate, decidedly futuristic though still in transition. By its old spelling, Calcutta readily conjures images of human suffering to most Westerners – although that's not a complete picture of this 330-year-old metropolis. Locally, Kolkata is regarded as India’s intellectual, artistic and cultural capital. Although poverty is certainly apparent, the self-made middle class drives the city's core machinery, a nascent hipster culture thrives among its millennial residents and its dapper Bengali gentry frequent grand colonial-era clubs.

Delstaten Goa på Indiens västkust är sedan länge känd för sin festliga och avslappnade atmosfär. Men nu har myndigheterna infört förbud mot både alkohol och grillning på stränderna.

Hyderabad, one of Islamic India's greatest cities, is reason enough on its own to visit this region. Its skyline is a sight to behold, defined by the great domes and minarets of ancient mosques, mausoleums and palaces of once-mighty dynasties. Delve inside the city's fabled old quarter for fascinating street markets, Sufi shrines, teahouses and biryani restaurants. Meanwhile, Hyderabad's newer districts are awash with the upmarket restaurants of IT-fuelled economic advancement.

A kaleidoscopic blend of Indian and Portuguese cultures, sweetened with sun, sea, sand, seafood, susegad and spirituality, Goa is India's pocket-sized paradise.

Visakhapatnam – also called Vizag (vie-zag) – is Andhra Pradesh’s largest city, famous for steel and its big port, but also doubling as a beach resort for sea-breeze-seeking domestic tourists. During the main December–February holiday season there's a distinctly kitschy vibe, with camel rides and thousands of bathers (though no swimmers).

Sikkim was its own mountain kingdom till 1975 and still retains a very distinctive personality. The meditative, mural-filled traditional monasteries of Tibetan Buddhism coexist with Hindu shrines of the ever-growing Nepali community, with both religions creating some astonishing latter-day megasculptures to adorn the skyline.

Founded in 1577 by the fourth Sikh guru, Guru Ram Das, Amritsar is home to the spectacular Golden Temple, Sikhism's holiest shrine and one of India’s most serene and humbling sights. The hyperactive streets surrounding the temple have been calmed to some extent by recent urban landscaping, including graceful pedestrianised walkways, but duck into any side alley and you’ll soon discover Amritsar’s fantastically frenetic old-city bazaars, sheltering a sensory overload of sights, sounds and smells.

There are few states more quintessentially Indian than Uttar Pradesh. The subcontinent's historic and religious roots – Hindu, Buddhist, Islamic and secular – intertwine in this land of sacred rivers and vast plains, manifesting in sights of profound importance.
