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.

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.

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.

Founded in the mid-17th century as a winter quarters for traders and tax collectors, Irkutsk came to prominence in the 1800s. Participants in the Decembrist revolt against Tsar Nicholas I were exiled to Siberia in droves, turning Irkutsk into their cultural center. Today, it’s one of Siberia’s biggest and most important cities, with over half a million people, many universities, many historic churches and museums, and beautiful Lake Baikal, just about an hour away by train.

Grindelwald is postcard-perfect, a charming example of a Swiss ski resort. There are slopes for all experience levels, plus plenty of snowy activities for those who don’t ski, such as sledding, hiking or snowshoeing. Not feeling particularly active? Just cozy up by crackling fire and enjoy the merry atmosphere. After a long day, nothing’s better than lingering over a pot of Swiss fondue and a glass of crisp wine as you plan the next day’s adventures.
