Cambridge might be best known for its university, home to some of the world’s greatest minds (Milton, Darwin, Hawking, etc.). But there’s a vibrant theater and arts scene here as well, and you’ll find fantastic contemporary restaurants mixed in with traditional pubs. Climb the tower of Great St. Mary’s Church for sweeping views of the city.

In the "city of dreaming spires," academia takes center stage. Gaze out at Oxford's world-famous university from the top of Carfax Tower before heading into the city's pedestrian-friendly streets. Follow your nose to the Covered Market for the makings of a picnic to enjoy at Headington Hill Park. Mix the historic and modern with visits to the 12th-century village church of Iffley and trendy Cowley's ethnic shops and music venues.

Southwest of London is Southampton (Soton to the locals), a metropolitan area centered around the port. However, tucked away on the side streets are ancient gems such as the Tudor House, Mottisfont Abbey, and "God's House," a museum located in a tower in the medieval wall. The ultra-modern Sea City Museum celebrates Southampton's seafaring past and the RMS Titanic. Looking for nightlife? Travelers can dance the hours away with bars, clubs, and live music, all accessible by public transportation.

Breezy Madeira is an eponymous island in the Madeira Islands, a Portuguese archipelago. The capital city of Funchal was settled in the 15th century and is a colorful collection of gardens, religious sites, and quirky tourist attractions like the thatched-roof Madeira Story Centre. Hike to the summit of Pico Ruivo and you’ll feel like you’ve climbed through the clouds. Unwind over a glass of Madeira wine, an historic fortified beverage that’s musky and subtly sweet.

Over the centuries, many cultures have added their mark to this prized piece of land. Today, you can experience those influences firsthand by exploring Istanbul’s mahalles (neighborhoods). From the holy sites of Sultanahmet and the 19th-century European elegance of Beyoğlu to the high fashion of Nişantaşı, the vibrant café society of Kadıköy and the football-loving streets of Beşiktaş, it’s easy to see why travelers say that Istanbul isn’t just one city, but many cities within one.

The largest of the twelve Dodecanese islands on the Aegean's eastern edge, Rhodes is also its most popular. The well-preserved medieval city of Rhodes sits at the north of the island of the same name. High rise hotels line the northern and eastern coastlines. Small villages and resorts dot the island's other shores. Whether your interests are beaches, bars or ancient sites, Rhodes offers an abundance of all three. Authentic Greece can be found in the hilly interior of the 50-mile long island.

The Pearl of the Mediterranean has an ambiance more in keeping with its neighbors to the north than with those in the Middle East. Site of Pharos lighthouse, one of the Wonders of the World, and of Anthony and Cleopatra’s tempestuous romance, the city was founded by Alexander the Great in 331 BCE. Today, Alexandria offers fascinating insights into its proud Greek past, as well as interesting mosques, the casino strip of the Corniche, some lovely gardens and both modern and traditional hotels.

Cairo’s an ancient city that also happens to be a modern metropolis—it’s one of the biggest cities in the Middle East and has the traffic and noise issues to prove it.

Even within the midst of the ultra-modern commercial center, there is evidence of its ancient roots, with colorful souks, Roman ruins, cultural museums and monuments painting a picture of the history of the region.

Atmospheric backstreets paint a very different picture to first impressions of Abu Dhabi. The often slick and modern capital of the U.A.E. presents a fascinating mixture of tradition and progression. Tracing its rich history back to around 3000 B.C., Abu Dhabi maintains a more distinctly Arabian ambiance than glitzy Dubai. Taxis are a safe, reliable way to get around sites such as The Corniche Park, the White Fort, the Heritage Village, which offers glimpses into Bedouin life, and the Women's Craft Centre.

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