In Venice, "Water Taxi" (Motoscafi) services operate 24 hours a day, 7 days a week, so there is technically no "last" taxi. Unlike the public Vaporetto (water bus), which has a scheduled "Night" (N) service and ends its regular daytime routes around midnight, private water taxis are a premium, on-demand service that can be booked at any time. However, if you are looking for the last Vaporetto (the much cheaper public option), the main lines like Line 1 or 2 typically transition to the "N" route starting between 11:30 PM and 12:30 AM. If you arrive at the airport (Marco Polo) late at night, the "Alilaguna" water shuttle also has a final departure usually around 12:15 AM. If you miss these, a private water taxi is your only option, and you will find them waiting at the airport pier or major hubs like Piazzale Roma and San Marco. Be aware that between 10:00 PM and 7:00 AM, a "night surcharge" (typically around €20–€30) is added to the already high base fare of the private taxis. In 2026, it is highly recommended to use the official "Consorzio Motoscafi Venezia" app to book a late-night taxi to ensure a fixed price and guaranteed pickup.
