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.

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.

A stunning introduction to southern India, Karnataka is a prosperous, compelling state loaded with a winning blend of urban cool, glittering palaces, national parks, ancient ruins, beaches, yoga centres and legendary travelers' hang-outs.

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).

Loket frustar otåligt. Så tar det sats och börjar skjuta sina rangliga trävagnar uppför de gröna sluttningarna i Blå bergen. Så värst fort går det inte. Men vad gör det? Det här är en sådan där tågresa som man inte vill ska ta slut.

Here is India's archetypal land of maharajas and medieval forts, palaces and tigers, and kaleidoscopic festivals. Rajasthan really is the jewel in India's crown.

Long considered the ‘wild east’ of India, Nagaland abounds in primeval beauty and tribal culture. Its dazzling hills and valleys, reaching right up to the India–Myanmar border, are other-worldly places where, until not long ago, headhunting Naga tribes fought off intruders and each other. Today Nagas have abandoned headhunting and turned to Christianity. Traditional lifestyles linger strongest in the north, where many people live in thatched longhouses and follow farming and hunting lifestyles. The sense of Naga identity among the 16 or 17 main tribal groups, with multiple languages but cultural similarities, is strong. Traditional attire comes out in full feather-and-spear colour at the many tribal festivals, above all December's Hornbill Festival near Kohima.

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.

Bihar is the birthplace of Buddhism – indeed its very name derives from vihara, the Sanskrit word for Buddhist monastery. Thousands of pilgrims from around the world throng its many places of religious significance. Most extraordinary among these spots is Bodhgaya, the site of Buddha's enlightenment, where getting caught up in the spiritual atmosphere is a major draw for travelers. In tribal Jharkhand, holy Parasnath Hill is a revered Jain pilgrimage site, and joining devotees on the hike to the top is a surreal highlight. That apart, the forests of Betla (Palamau) National Park promise a date with elephants and leopards, and maybe even the odd tiger.

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.
