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.

It’s nicknamed the Eternal City for a reason. In Rome, you can drink from a street fountain fed by an ancient aqueduct. Or see the same profile on a statue in the Capitoline Museum and the guy making your cappuccino. (Which, of course, you know never to order after 11 am.) Rome is also a city of contrasts—what other place on earth could be home to both the Vatican and La Dolce Vita?

Tossa del Mar has beautiful beaches—and tourists flock to them in summer, so make sure you have a reservation if you’re planning to visit in high season. Enjoy the seafront restaurants (and, of course, fresh-caught fish specialties) and many tapas bars in this charming Catalan town.

Perched serenely on the banks of a sparkling river, Eskilstuna is a charming medieval city in southeast Sweden. The trees near the towering Klosters church boast great puffs of pink blossoms, making for cinematic springtime. The Parken Zoo features animals from all over the world, including an impressive Komodo Dragon.
