One of the amazing activities that you shouldn't miss is to take a tour on the Grand Canal. Take the water bus (vaporetto) is an inexpensive and a great way to get some awesome pictures of the buildings lining it. You will see the bustling Venetian waterfront and iconic historical landmarks as traditional palazzos, stunning churches, the oldest and most famous bridge, etc.
Vaporetto tickets can be purchased in advance at
