Nearly crossing northern Italy from the Adriatic Sea westward, Emilia-Romagna gets its name from Via Emilia, the Rimini-to-Piacenza ancient Roman road it straddles. With a rich mix of age-old agriculture and modern industry, the region is home to many historic and cultural gems, both in its larger towns like Bologna, Modena and Ravenna, as well as in its many small hilltop villages. Of course, the region’s best offerings also include native culinary wonders like parmigiano cheese and tortellini.

A spot of white in the turquoise waters of the Aegean Sea, the island of Naxos is a unique blend of ancient ruins and beach culture. The largest of the Cycladic Islands, Naxos is the childhood home of none other than Zeus, king of the gods. Upon arrival in Naxos, hike over a causeway to Palatia, where the Portara, a stone gateway to an ancient temple that no longer exists, stands alone, the symbol of the island. At sunset, the views of the island, and the sea beyond, are breathtaking.

The largest game reserve in South Africa, Kruger National Park is basically a synonym for the word "safari." Home to over 500 bird species, 100 reptiles, nearly 150 mammals, multiple archaeological sites, and a stunningly diversity of trees and flowers, Kruger is the country’s flagship national park. Adventurers can explore the park in a 4x4, take a bush walk or fly above in a hot-air balloon.

Maybe your local zoo has lions, leopards, zebras or elephants. Maybe they even have wildebeest. But we bet they don't have 1.3 million wildebeest—never mind 1.3 million wildebeest in migration, with predators in hot pursuit. It's one of the most awesome sights in nature, and you can see it at Masai Mara in southwestern Kenya.

The Maasai call the plains of Serengeti National Park "the place where the land moves on forever"—so prepare to be astonished by its vastness. And here, you can witness the famous Serengeti annual migration, the largest and longest overland migration on earth.

Situated at the foot of the western Pyrenees near the French border, Spain's Basque country comprises three provinces: Guipúzcoa and the popular beachfront capital of San Sebastian; Viscaya, where capital Bilbao houses the jaw-dropping Gehry-designed Guggenheim Museum; and Alava, whose capital Vitoria teems with medieval architecture. Running with the bulls at Pamplona and drinking rioja from local wineries add to the region's exotic romanticism. Travel in early summer and autumn to avoid the crowds.
