Most people need very little motivation to add Venice to their list of must-see sights. The city makes you feel like you’re walking around in a postcard, and who doesn’t love that? In 2013, however, Venice gives you another reason to visit – Biennale. This major international arts festival only takes place in odd-numbered years, making 2013 another Biennale year. The festival runs from June through November, with exhibits ranging from art to dance to theater to music. Summer is a notoriously busy time in Venice, so if you want to avoid most of the crowds but still enjoy the arts, plan your trip for September-November after the summer rush.
