Ibiza, Balearic Islands
One of Europe's favorite playgrounds, Ibiza boasts more than 100 miles of coastline frosted with exquisite beaches. It's a hub of sun worship, white sand, beach bars and clubs that buzz all night. And there's history too. The fortified Old Town, known as Dalt Vila, is a UNESCO World Heritage site and a spectacular example of Renaissance military architecture. Carrer del Calvari leads to Portal Nou, the entrance through the old city walls, and a walk up the hill reveals panoramic views of the city.
