Now that casinos have spread in South Africa, Sun City is no longer the only gaming hotspot in the country, but it's still visually dramatic. Located two hours from Johannesburg, it's a sprawling complex of luxury hotels, restaurants and Vegas-style shows on the edge of Pilanesberg Game Reserve.

Hiking trails and art galleries abound in Stellenbosch, but it's wine that takes center stage. More than 100 wine cellars, most open to the public, surround the oak-lined South African town, and tasting tours operate daily. Winter brings a four-day festival celebrating the local vintages. The historic town center houses the trading-post style shop Oom Samie se Winkel, the Neo-Gothic Moederkerk church, and museums dedicated to toys, military memorabilia, autos and early life on the Cape.

The Zanzibar Archipelago, located in the Indian Ocean 15 miles off the coast of Tanzania, is a breathtaking spot to escape from the world. You’ll enjoy clear, turquoise-blue water; shallow sandbars perfect for wading; and many small, nearly deserted islands virtually unvisited by tourists. Explore the World Heritage Site of Stone Town, Zanzibar City’s old quarter. Or just go beach to beach between tiny fishing villages—each one's better than the next.
