The deep-cut Shayok and Nubra River Valleys offer tremendous scenery on a grand scale, with green oasis villages surrounded by thrillingly stark scree slopes, and harsh arid mountains, strongly reminiscent of Pakistan's Northern Areas. There are sand dunes, monasteries, a ruined palace and – at Turtuk and Bogdang – a whole different culture (Balti) to discover. Permits are required by foreigners.

South India’s most popular wildlife reserve, Periyar, encompasses 777 sq km, including a 26-sq-km 1895 artificial lake created by the British. This vast expanse – which became Kerala's first tiger reserve in 1978 (though founded as a sanctuary in 1934) – shelters wild boar, sambar, bison, langur, 2000 elephants and 35 to 40 hard-to-spot tigers. It's firmly established on both the Indian and foreigner tourist trails and known for its scenic lake cruise. But if you dig deeper, perhaps on a trek with a tribal villager or an ex-poacher, Periyar's hilly jungle scenery takes on a wild, magical feel. Bring warm, waterproof clothing.

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.

Kachchh, India’s wild west, is a geographic phenomenon. The flat, tortoise-shaped land, edged by the Gulf of Kachchh and Great and Little Ranns, is a seasonal island. During the dry season, the Ranns are vast expanses of dried mud and blinding-white salt. Come the monsoon, they’re flooded first by seawater, then by fresh river water. The salt in the soil makes the low-lying marsh area almost completely barren. Only on scattered ‘islands’ above the salt level is there coarse grass, which provides fodder for the region’s wildlife.

Varanasi is the India of your imagination. This is one of the world's oldest continually inhabited cities, and one of the holiest in Hinduism. Pilgrims come to the Ganges here to wash away sins in the sacred waters, to cremate their loved ones, or simply to die here, hoping for liberation from the cycle of rebirth.

Rimmed by layers of alpine peaks, the 140km-long Kashmir Valley opens up as a giant, beautiful bowl of lakes and orchards. Tin-roofed villages guard terraced paddy fields delineated by apple groves and pin-straight poplars. Proudly independent-minded Kashmiris mostly follow a Sufi-based Islamic faith, worshipping in distinctive wooden mosques with central spires, and they are fiercely proud of their homeland. It's a stunningly beautiful place, but one wracked by political violence in recent decades.

Thiruvananthapuram, Kerala's capital – still usually referred to by its colonial-era name, Trivandrum – is a relatively compact but energetic city spread across low-lying hills and is an easygoing introduction to urban life down south. Most travelers merely springboard from here to the nearby beaches of Kovalam and Varkala, but Trivandrum (once capital of the princely state of Travancore) has enough good food and intriguing sights – including a zoo, a Travancore palace and a cluster of Victorian museums in glorious neo-Keralan buildings – to justify a stay.

Welcome to the British Raj. New Delhi was designed on an imperial scale after George V decided to move the capital of British India from Calcutta to here in 1911. Much of the colonial footprint remains today, including the circular, colonnaded shopping precinct Connaught Place, the imposing government buildings that look out along Rajpath, and the rambling bungalows, some of which now house museums.

Ahmedabad (also called Amdavad, Ahmadabad or Ahemdavad), Gujarat's major city, will bowl you over. Its incredible architecture ranges from centuries-old mosques and mausoleums to cutting-edge contemporary design — and then there's the old quarter, where the narrow streets hide excitement around every twisting corner. Throw in some excellent museums, fine restaurants and a bustling street-food scene and you end up with a city that rightly deserves its place as India's first Unesco Urban World Heritage Site.
