Steeped in history, thronged with people and buzzing with commerce, the Old City of Hyderabad is one of India's most evocative ancient quarters. Exploring the lanes of this district, with its chai shops and spice merchants, you'll encounter a teeming urban masala of colour and commerce. Looming over the Old City is some of Islamic India's most impressive architecture, in varying states of repair. Most visitors concentrate their time in this area, though the magnificent Golconda Fort should not be missed either.

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.

Most people travel to Bihar to visit the hallowed Buddhist circuit of Bodhgaya, Rajgir, Nalanda and Vaishali, with Patna as a transport hub. It's not the easiest state to visit, with limited English spoken and higher than normal levels of chaos, but explorers will enjoy tracking down the many fascinating, off-the-beaten track destinations waiting to be discovered.

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.

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.

With sublime silken-blonde beaches, twinkling teal shallows and some of the best diving in South Asia, thickly forested Havelock (Swaraj) enjoys the well-deserved reputation of being a travellers' paradise. Indeed, for many, Havelock is the Andamans – it's what lures most visitors across the Bay of Bengal, many of them content to stay here for the entirety of their trip.

Sprinkled with Islamic and British Raj–era architecture, stuffed with fascinating bazaars and famed throughout India for its food, the capital of Uttar Pradesh is something of a sleeper: plenty worth seeing, but often overlooked by travelers. Central Lucknow features wide boulevards, epic monuments and several parks and gardens that contribute to an atmosphere of faded grandiosity.

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.

The beating heart of India, this incredible neighborhood will knock you sideways with the power of its sights, sounds and smells, and with its unrelenting chaos. But if you can survive that first hit, you'll soon realize you've just landed in one of the world's truly special places. Prepare to be amazed.

Strung out along a ridge with steep forested hillsides falling away in all directions, the Himachal capital is one of India's most popular hill resorts, buzzing with a happy flow of heat-escaping Indian vacationers. Traffic is banned from the central part of town, so walking is pleasant – even when huffing and puffing uphill. The long, winding main street, The Mall, runs east and west just below the spine of the hill. South of it, the maze-like alleys and stairways of the bustling bazaar cascade steeply down to Cart Rd.
