Plan to cross many bridges when in Cork. Ireland's third-largest city began life as an island and now spans both banks of the River Lee, with watery channels running beneath some of its main thoroughfares. The best way to experience this hilly southern seaport is on foot, following the signposted walking tour past St. Finn Barre's Cathedral and the riverside quadrangle of University College up the hill to red and white Shandon Church. Along the way, you'll meet plenty of the city's talkative residents.

Dubai is a destination that mixes modern culture with history, adventure with world-class shopping and entertainment.

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.

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.
