Indien

This ethereally beautiful valley stretches up through touristy, forest-ringed Kasol and the busy if grubby little pilgrim hot-springs town of Manikaran to a collection of villages around Barshani with glorious views of 5000m Himalayan peaks. Places like Pulga and Kalga here are key stops on the pre-Goa 'hummus trail' for young Israeli travellers, while Kasol and Tosh increasingly draw young Indian travellers and weekenders. The valley has plenty of hippie/backpacker hang-outs, with cheap accommodation, international food and nonstop music. The well-deserved reputation for charas (hashish) is most noted at the very odd village of Malana. Police sometimes make spot checks for drugs.

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.

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.

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.

Welcome to the lush Western Ghats, some of the most precious heat relief in India. Rising like an impassable bulwark of evergreen and deciduous tangle, from north of Mumbai to the tip of Tamil Nadu, the World Heritage–listed Ghats (with an average elevation of 915m) contain 27% of India’s flowering plant species and an incredible array of endemic wildlife. In Tamil Nadu they rise to over 2000m in the Palani Hills around Kodaikanal and the Nilgiris around Ooty. British influence lingers a little stronger up in these hills, where colonialists built 'hill stations' to escape the sweltering plains and covered slopes in neatly trimmed tea plantations. It’s not just the air and (relative) lack of pollution that’s refreshing – there’s a certain acceptance of quirkiness and eccentricity here. Expect organic farms, handlebar-moustached trekking guides and leopard-print earmuffs.

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.

Uttarakhand is a place of myth and mountains. Hindus think of it as Dev Bhoomi – the Land of Gods – and the dramatic terrain is covered with holy peaks, lakes and rivers. Twisting roads and high-altitude hiking trails lead to spectacular pilgrimage sites where tales from Hindu epics are set. Though the presence of Shiva and Parvati (in a few of her forms) tower over the state, the imprint of British colonialism is equally apparent: the legend of hunter Jim Corbett lives on in the famed tiger reserve that bears his name; popular holiday towns were once Raj-era hill stations; and the Beatles turned Rishikesh into a magnet for spiritual seekers and yoga practitioners worldwide.

Sometimes the Seven Sisters of the Northeast (the states of Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland and Tripura) hardly seem like India at all. The region's hundreds of tribes and subtribes are slowly ceding to modernity, but remain extremely diverse. Nagaland's former headhunters now go to church on Sundays. Many Arunachalis also attend church-like buildings on Sundays – to worship the sun and moon. Cloudy Himalayan valleys near the border of Tibet are dotted with colorful monasteries, echoing with Buddhist chants and clashing cymbals.

South Goa is the more serene half of the state, and for many travelers that’s the attraction. There are fewer activities and not as many bars, clubs or restaurants, but overall the beaches of the south are cleaner and not as crowded as those in the north.

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.
