Mighty Mehrangarh, the muscular fort that towers over the Blue City of Jodhpur, is a magnificent spectacle and an architectural masterpiece. Around Mehrangarh’s base, the old city, a jumble of Brahmin-blue cubes, stretches out to the 6-mile-long (10km), 16th-century city wall. The Blue City really is blue! Inside is a tangle of winding, glittering, medieval streets, which never seem to lead where you expect them to, scented by incense, roses and sewers, with shops and bazaars selling everything from trumpets and temple decorations to snuff and saris.

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.

Lahaul is braced for massive changes. For years, reaching this spectacular if desolate region has involved crossing the seasonal, infamously treacherous Rohtang Pass. However, by 2020 the new Rohtang Tunnel is expected to have opened, making access a breeze from Manali. In its wake, you can expect a rush of new tourism.

There are few more refreshing Tamil Nadu moments than leaving the heat-soaked plains for the sharp pinch of a Kodaikanal night or morning. This misty hill station, 75 miles (120km) northwest of Madurai in the protected Palani Hills, is more relaxed and intimate than its big sister Ooty (Kodai is the ‘Princess of Hill Stations’, Ooty the Queen). It’s not all cold either; days feel more like deep spring than early winter.

Chennai may be the capital of Tamil Nadu, but Madurai claims its soul. Madurai is Tamil-born and Tamil-rooted, one of the oldest cities in India, a metropolis that traded with ancient Rome and was a great capital long before Chennai was even dreamed of.

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.

Separating the Assam valley from the plains of Bangladesh, hilly Meghalaya (‘the abode of clouds’) is a cool, pine-fresh mountain state set on dramatic horseshoes of rocky cliffs. Cherrapunjee and Mawsynram are among the wettest places on Earth; most of the rain falls between June and September, creating very impressive waterfalls and carving out some of Asia’s longest caves.

For many visitors, particularly cashed-up young Indian tourists from Bangalore and Mumbai plus Europeans on package holidays, this is Goa’s party strip, where the raves and hippies have made way for modern thumping nightclubs and wall-to-wall drinking. The Calangute market area and the main Baga road can get very busy but everything you could ask for – from a Thai massage to a tattoo – is in close proximity and the beach is lined with an excellent selection of increasingly sophisticated restaurant shacks with sunbeds, wi-fi and attentive service.

Stretching 600km along the Brahmaputra River Valley, with a spur down to the hilly southeast, Assam is the largest and most accessible of the Northeast States. Well known for its national parks abounding in rhinoceroses, elephants, deer and primates (with respectable tiger numbers too), it welcomes visitors with a subtly flavoured cuisine and a hospitable population with a vibrant artistic heritage. The archetypal Assamese landscape is a golden-green panorama of rice fields and manicured tea estates, framed by the blue mountains of Arunachal Pradesh in the north and the highlands of Meghalaya and Nagaland to the south. The birthplace of Indian tea, Assam has more than 3000 sq km of land carpeted in bright-green tea gardens, and visits to these estates are high on many travellers' itineraries.

Steeped in history yet overflowing with modern life, colorful, cacophonous Delhi pulsates with the relentless rhythms of humanity like few other cities on Earth.
