If you haven't been to Venice, it's time to leave the world behind. Unspoiled by mass tourism, this impressive city is filled with art, history, beauty and mystery – all within easy reach of its canals. The grandeur of St. Mark's Basilica and tour boats leaving from its square will leave you breathless; but don't leave without checking out the Biennale and Carnevale, two amazing annual flower shows that take place throughout February and March.
