Indien

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.

Like a giant wedge plunging into the ocean, South India is the subcontinent's steamy heartland – a lush contrast to the peaks and plains up north.

Separated from fertile Lahaul by the soaring 4551m Kunzum Pass, the trans-Himalayan region of Spiti is another chunk of Tibet marooned within India, a kind of 'mini-Ladakh' with fewer tourists. The scattered villages in this serrated moonscape arrive like mirages while the turquoise-grey ribbon of the Spiti River is your near-constant companion, albeit sometimes way below in precipitous gorges.

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.

Spectacularly jagged, arid mountains enfold this magical Buddhist ex-kingdom. Picture-perfect gompas (Tibetan Buddhist monasteries) dramatically crown rocky outcrops next to fluttering prayer flags and whitewashed stupas, while prayer wheels spun clockwise release merit-making mantras. Gompa interiors are a riot of golden Buddhas and intricately colourful murals and home to red-robed monks. It's a little corner of Tibet marooned in the furthest reaches of India.

Ever since the Beatles visited the ashram of the Maharishi Mahesh Yogi in the late '60s, Rishikesh has been a magnet for spiritual seekers. Today it styles itself as the ‘Yoga Capital of the World’, with masses of ashrams and all kinds of yoga and meditation classes. The action is mostly north of the main town, where the exquisite setting on the fast-flowing Ganges River, surrounded by forested hills, is conducive to meditation and mind expansion. In the evening, an almost supernatural breeze blows down the valley, setting temple bells ringing as sadhus ('holy' men), pilgrims and tourists prepare for the nightly ganga aarti (river worship ceremony). You can learn to play the sitar or tabla; try Hasya yoga (laughter therapy), practise meditation or take a punt on crystal healing.

A sliver of fertile and densely populated land running from the tea-draped Himalayan foothills to the steamy mangroves of the Bay of Bengal, West Bengal presents a remarkable range of destinations and experiences within a single state. In the tropical southern areas, the wildlife-rich, mangrove-lined waterways of the Sundarbans vie for attention with Bishnupur's ornate terracotta Hindu temples and the cultured, arty vibes of Shantiniketan. Upstream from Kolkata (Calcutta) on the Hooghly River (a branch of the Ganges) you'll reach old European trading towns and three former Bengali capitals at Murshidabad, Gaur and Pandua. The cool northern hills are home not just to British colonialist hill stations like bustling Darjeeling and more laid-back Kalimpong, but also to fantastic vistas of massive Khangchendzonga, rolling green tea estates, some great hiking and the huffing and puffing 'toy trains' of the almost 140-year-old Darjeeling Himalayan Railway.

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.

A Portuguese colony for 426 years, tiny Diu island, linked by a bridge to Gujarat’s southern coast, is still infused with the history, architecture and, in some places, the cultural remnants of its European colonizers. The streets of the main town are clean, colorful and quiet once you get off the tourist-packed waterfront strip, and there are numerous crumbling Portuguese villas and churches. Although it's often thought of as being part of Gujarat, this is incorrect. With Daman it's actually a separate union territory known as Daman and Diu, and it has its own rules and government.

Udaipur has a romance of setting unmatched in Rajasthan and arguably in all India – snuggling beside tranquil Lake Pichola, with the purple ridges of the Aravalli Range stretching away in every direction. Fantastical palaces, temples, havelis (traditional, ornately decorated residences) and countless narrow, crooked, timeless streets add the human counterpoint to the city’s natural charms. For the visitor there's the serenity of boat rides on the lakes, the bustle and color of bazaars, a lively arts scene, the quaint old-world feel of its heritage hotels, tempting shops and some lovely countryside to explore on wheels, feet or horseback.
