This resort town, with its great beaches, has a bit of a Spring Break atmosphere (the parties start in the late afternoon and go all night). If dancing in a bikini is not your thing, though, no worries—you can explore a mediaeval monastery or enjoy cruises on the lovely blue water. Families will want to visit Water World, the biggest theme waterpark in Europe.

Sometimes referred to as the capital of Africa, Addis Ababa is a buzzing hub of economic, social and political activity and home to such notable offices as the African Union and the United Nations Economic Commission for Africa. The diversity of its people is reflected in the many churches, mosques and museums, including the Ethiopian National Museum which houses the fossilized skeleton of Dinkinesh, or Lucy, the Australopithecine discovered in the area in the 1970s.

If it's your first time visiting the Amalfi Coast, chances are you'll do a double-take the first time you see a roadside lemon stand. Yes, those are lemons, and yes, they are the size of your head. But despite their freakish appearance, you will grow to love these lemons because the locals use them to produce limoncello. And take it from us, there's nothing like a glass of limoncello as you gaze out at the sea from the balcony of your hotel in Amalfi. It's pretty much perfection.

Procida is the quintessential Mediterranean paradise, an absolute vision of colourful harbourside homes and picturesque piazzas. Lose yourself in colourful Terra Murata, a walled medieval town that’s perched staunchly on a hill. There you’ll find the 15th-century Palazzo D’Avalos and Abbazia di San Michele, an 11th-century Benedictine abbey. After your tour, scoot down the steps to charming Corricella, then unwind with a poolside cocktail at the magical Maresia Solarium.

Known as Dreiflüssestadt (City of Three Rivers), Passau is the place where the Danube meets the Inn and the Ilz. The picturesque city lies in Germany’s far southeast corner near the Austrian border. Settled since prehistory and a former hub of the salt trade, it became the Roman village of Batavis, then later the Holy Roman Empire’s largest diocese and a sword-making center. Saint Stephan’s Cathedral, home of the world’s second-largest cathedral organ, is one of Passau’s favorite attractions.

Olbia (Greek for “happiness”) is a popular jumping-off point for those visiting the white-sand beaches of the Costa Smeralda, but those who linger in the coastal city uncover a historic centre filled with archaeological landmarks, piazzas ringed by wine bars, and authentic eateries.
