Located on the far west end of Venice, this small cruise ship and ferry terminal is a short but ugly walk to the Piazzale Roma. Another option is the inexpensive People Mover monorail, which links the port area to Piazzale Roma and Tronchetto.
The terminal has a left luggage facility, but do check its opening hours. There's another one in Piazzale Roma.
