By foot from Venice to Venice (city)
The Port of Venice is big and there are several docks and cruise terminals. At first sight it may seem a little difficult to find your way to the city center, but actually it's very easy.
Leave the port through the big gate and turn right. You will see that the center is already indicated. After you have crossed the first bridge (there will be many more!) you arrive at Piazzale Roma. This is an important transportation hub to and from the city. Highlights such as Piazza San Marco and Ponte Di Realto are already indicated from here. Follow the signs through the maze of streets, canals and squares.
TIP: It's possible to walk to the center of Venice, but the first part is pretty boring. You can take the People Mover to skip the first part.
