The Indian and colonial influences in this South African beach city can’t be missed, and the blend of cultures and architecture makes Durban unique in South Africa. Durban’s Golden Mile is a destination for surfers, families and fisherman, due to its blend of natural beauty and modern resort. Major-city attractions abound, making this a good destination for families and couples alike.

South Africa’s most popular tourist destination offers the urban thrills of Cape Town, its adjacent wine country and an aura of the rich political history of South Africa. The Overberg's perfect whale-watching perches provide excitement of a different nature. The Garden Route's lakes and forests and the Klein Karoo's ostrich-farming towns and vineyards present another take on the Cape. For extra kicks, try bungee jumping or cage-diving among Great Whites.

Miles of powder-white beaches hug the coast at Belle Mare, where championship golf courses, posh resorts, a family-friendly water park and abundant aquatic sports ensure activity-filled days. Deep-sea fishing for tuna, marlin and mako shark is especially popular in this eastern Mauritius enclave. Belle Mare also serves as a convenient base camp for a trek to 1,575-foot Lion Mountain, where sweeping views reward those who make the challenging hike to its peak.

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. But as long as you’re not looking for solitude, Cairo—the City of the Thousand Minarets—is a splendid place to explore Egyptian history and culture. (Editor's note: Our list was compiled before political unrest prompted many countries to issue travel warnings for Egypt. If you're currently planning a trip to Egypt, please consider the risks and monitor your government's travel alerts.)

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 (neighbourhoods). 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 travellers say that Istanbul isn’t just one city, but many cities within one.

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.
