Located near the National Capital Region of Delhi, this upcoming district houses numerous multinational companies and as a result, has plenty of tourist-friendly malls, hotels and restaurants. The area's top attraction is the Sheetla Mata temple, a popular pilgrimage site named for the Indian goddess who could dispel small pox; a festival is held there in March and July. For a more rural setting, visit nearby Sohna, which is surrounded by ancient ruins and known for its hot springs.

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.

Iceland’s biggest city, Reykjavik bears the distinction of being the world’s northernmost capital, and for virtually every Icelandic visitor it serves as a gateway, just to the city itself or to the rugged adventure options beyond. Founded in the country’s southwest at the end of the 18th century, Reykjavik has been Iceland’s cultural hub ever since. These days, that culture includes a hip and internationally recognised music and arts scene, not to mention a notoriously wild nightlife.
