Popularly referred to as Ooty, this gem among southern hill resorts is covered in eucalyptus and pine trees and coffee and tea plantations. On a clear day, it's possible to see as far as the Mysore plateau from Dodabetta Peak, the district's most prominent viewpoint. The Stone House, a landmark 1822 bungalow, and St. Stephen's Church are remnants of the area's first British settlement. Also noteworthy: formal botanical gardens, a children's mini-garden and a contemporary art collection.

Kodaikanal has an endangered animal called the grizzled giant squirrel. To us, that alone is reason to book a trip ("grizzled giant squirrel" might be the best animal name ever). Perched on the woodsy southern crest of the Palani Hills, nearly 7,000 feet above sea level, this popular lakeside resort town is a magnet for nature lovers. Wander the peaceful slopes, keeping an eye out for birds, exotic flowers and, of course, grizzled giant squirrels.

Sprawling tea plantations surround the serene hills of Munnar, which attract adventure travellers hungry for paragliding, treks to Anaimudi (South India's highest peak) and hikes originating at the confluence of three mountain streams. The stone Christ Church, built by the British in 1910, is adorned with renowned works of stained glass, and Eravikulam National Park, about 10 miles away, is home to equally colourful wildlife, including the endangered Nilgiri Tahr (ibex), ruddy mongoose and 120 bird species.

The city of Mahabaleshwar is a pinnacle of greenery, boasting one of the only evergreen forests in the world. The landscape abounds with lush hills, valleys and lookout points such as Lodwick Point, Arthur's Seat and Babington Point, all of which offer spectacular views. Trot along on horseback for a delightful four-legged tour of the gorgeous Venna Lake area, and savour juicy native strawberries, mulberries and corn.

Mumbai (formerly known as Bombay), India, is famous for its chaotic streets. For bargains and people-watching, outdoor bazaars top the list of attractions. Popular waterfront destinations are Marine Drive, where visitors go to watch the sun set over the Arabian Sea, and the carnival-like Juhu Beach. More sightseeing options are the Gandhi Museum, in the leader's former home, and the cave temples of Elephanta Island. For tranquillity, Mumbai has many religious sites, lakes and parks.

Laid out by British architect Edwin Lutyens, the Indian capital is a striking modern metropolis. A gracious contrast to Old Delhi's winding streets, the grand avenues and stately buildings of New Delhi are rich with history and culture, from Gandhi's Delhi home (and the site of his assassination) to the tomb of Humayun, a complex of Mughal buildings reminiscent of the Taj Mahal. Chaotic traffic is best left to the locals. Negotiate a good price for taxis or travel on the new Delhi Metro.

Darjeeling, nestled among rolling mountains, is a perfect destination for outdoor enthusiasts. Popular places to visit include Tiger Hill, Batasia Loop and the War Memorial, and the Himalayan Zoological Park and Snow Leopard Breeding Center. What should you bring home?

Established in the Himalaya foothills by a British Army officer in 1820, the "Queen of the Hills" stands above the rest with its deep woods, favorable climate and Doon Valley views. Its name is derived from the berry-covered Mansur shrub found in abundance around this trekker-friendly area. Vestiges of its colonial past are still reflected in the cuisine and architecture. For stunning natural sights, head to Gun Hill or Childer's Lodge, the two highest peaks, or the famous Kempty waterfall.

The capital of the state of Sikkim, Gangtok is an attractive tourist destination, reflecting a unique ambience which derives from its happy blend of tradition and modernity.
