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.

When Swiss architect Le Corbusier was commissioned with the job of designing Chandigarh from scratch in 1950, he conceived a people-oriented city of sweeping boulevards, lakes, gardens and grand civic buildings, executed in his favourite material: reinforced concrete. Seventy years on and the parks, monuments and civic squares are all still here, albeit somewhat aged.

Irreverent, cheerful and pleasantly boisterous, Sikkim’s modern capital is layered along a precipitous mountain ridge, descending the hillside in steep tiers. Viewpoints survey plunging green valleys that remain beautiful even when partly shrouded in mist. If the weather plays ball, look for glimpses of snow-topped Khangchendzonga on the distant skyline. More than specific sights, Gangtok is appealing as a place for post-trek R & R or for meeting fellow travelers to organise group tours and permits. The city's mostly pedestrianised social-commercial heart is Mahatma Gandhi (MG) Marg, packed with restaurants, shops, travel agents and a bustling early-evening passeggiata of relaxed wanderers. High above, the contrastingly calm central ridgetop links manicured gardens and an almost jungle-like area around the Chogyal Palace (former royal residence).

For many travelers, Kerala is South India's most serenely beautiful state. This slender coastal strip is defined by its layered landscape: almost 373 miles (600km) of glorious Arabian Sea coast and beaches; a languid network of glistening backwaters; and the spice- and tea-covered hills of the Western Ghats, dotted with fiercely protected wildlife reserves and cool hill stations such as Munnar. Just setting foot on this swathe of soul-soothing, palm-shaded green will slow your subcontinental stride to a blissed-out amble. Kerala is a world away from the hectic action of the rest of India, its long, fascinating backstory illuminated by historically evocative cities like Kochi (Cochin) and Thiruvananthapuram (Trivandrum).

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.

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.

Bikaner is a vibrant, dust-swirling desert town with a fabulous fort and an energising outpost feel. It’s less dominated by tourism than many other Rajasthan cities, though it has plenty of hotels and a busy camel-safari scene, which attracts plenty of travelers looking to avoid the crowding that occasionally occurs around Jaisalmer-based safaris.

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.

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.

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.
