The letters A, B, C and D are not vaporetto routes. They identify individual boarding docks, or approdi, inside a larger ACTV stop area. Venice vaporetto platforms matter most at busy hubs such as Ferrovia, Rialto, Piazzale Roma, Fondamente Nove and San Zaccaria, where the correct boat may leave from a dock tens or even hundreds of metres from another dock with the same stop name. Always match three things before joining a queue: your line number, your direction or destination, and the letter shown for that departure.
There is no citywide rule that A means one direction and B means the other. The letters only make sense at the stop where you are standing. A Line 1 departure might use A at one stop, E at another, and move to a different letter later in the evening.
What A, B, C and D actually mean
ACTV calls an individual boarding point an approdo. You may also hear pontile for a pier or see imbarco for boarding. At small stops, there may be only one obvious floating pontoon. At major interchange points, several separate pontoons share the same general stop name, so ACTV gives them letters.
Think of the letter as the equivalent of a platform number at a railway station. It tells you where to wait, but it does not tell you where the boat is going.
The important distinction is:
- Line number: the service, such as 1, 2, 4.1, 4.2, 5.1, 5.2 or 12.
- Direction: the side of the route you need, usually indicated by major destinations.
- Dock letter: the physical boarding point for that particular departure.
This is one reason simply telling someone to “take Line 1 from Rialto” is incomplete. Line 1 runs in both directions. You still need to know whether you are heading toward Ferrovia and Piazzale Roma or toward Accademia, San Marco and Lido, then find the dock assigned to that direction.
How to find the correct boarding dock
- Find the correct named stop first. Do not use the nearest yellow ACTV sign just because it says a familiar landmark. Around San Marco in particular, several separate boarding areas serve the same general part of the city.
- Look for the stop map. The useful heading is mappa degli approdi, meaning map of the waterbus boarding points.
- Find your line number and direction. Look at the destinations printed beside the route number. The word per means “to” or “toward.”
- Note the large letter beside that departure. That is the pontoon you need.
- Check the electronic information as well. Temporary changes, evening services and operational disruptions can send a boat to a different dock.
- Validate before boarding. ACTV requires tickets to be validated at the start of a journey and again when changing service or vehicle. Follow the validator instructions before entering the boarding area.
- Check the arriving boat one final time. Route number and destination matter more than the crowd standing beside you.

Ferrovia: A to E in front of Santa Lucia station
Walk out of Venezia Santa Lucia railway station and the Grand Canal is directly in front of you. The ACTV boarding area here is called Ferrovia, not Santa Lucia.
The current official stop map shows docks A, B, C, D and E arranged along the waterfront near Ponte degli Scalzi. Different route families use different pontoons.
A useful example is Line 2. In the current arrangement, one direction uses A for boats heading toward Piazzale Roma, Tronchetto, Giudecca and San Zaccaria, while the opposite direction uses B for Rialto, San Marco and Lido. Lines 4.1, 4.2, 5.1 and 5.2 use other letters.
Line 1 is a good warning against memorising a letter. Its Ferrovia boarding point changes for some late-evening departures. If you return to the station at night and stand where you boarded that morning, check the timetable panel again rather than assuming nothing has changed.
With a suitcase, do this before entering a queue. The pontoons are close enough to look like one stop but far enough apart that discovering you need the opposite end when the boat is arriving can cost you the departure.
Rialto: the two groups are about 50 metres apart
Rialto is particularly easy to misread because the current ACTV map divides the boarding area into two groups: A and B together, then C and D roughly 50 metres away.
During the main part of the day, the current map assigns Line 1 toward Ferrovia and Piazzale Roma to A, with the opposite direction toward Accademia, San Marco and Lido from B. Later in the evening, some Line 1 departures transfer to the C and D side.
Line 2 normally uses C or D here, depending on direction. That means two people can both be “waiting for a vaporetto at Rialto” while standing at different pontoons and both be correct.
If you are changing direction at Rialto, do not expect the return boat to leave from the same shelter. Read the large yellow letter signs before settling in.
San Marco-San Zaccaria: where the letters spread out
The San Zaccaria waterfront is the clearest example of why the letters matter. The official map currently shows A, B, B1, C, D, E and F stretched along the Riva degli Schiavoni. ACTV marks gaps of roughly 40 metres and 70 metres between some groups.
That can turn “just go to the next platform” into a several-minute walk through crowds, especially with rolling luggage or a stroller.
The present arrangement includes:
- A for services including Line 14 toward Lido and Punta Sabbioni.
- B for ACTV services toward Giudecca, Tronchetto and Piazzale Roma, plus Line 20.
- B1 for Alilaguna services. This is especially important because Alilaguna is a separate operator from ACTV.
- C and D for several services running toward the Grand Canal, Giudecca, Ferrovia and Piazzale Roma.
- E and F for services heading in the other direction toward places including Fondamente Nove, Murano and Lido.
AVM introduced a more directional layout here to make passenger flows clearer and reduce conflicting movements. Even so, you should treat the posted information on the day as authoritative because maintenance, events and operational changes can alter assignments.
Fondamente Nove: the letter mistake that can mean a 100-metre dash
Fondamente Nove is one of Venice’s main departure points for the northern lagoon. The official stop diagram shows A separated from the central B/C group by about 100 metres, with D another short distance beyond them.
That is a meaningful distance when your boat is already pulling in.
At present, Line 12 toward Murano, Burano, Torcello and Treporti uses A. Other services to Murano, Lido, San Marco, Ferrovia and Piazzale Roma use different pontoons. Travelers heading out to the islands should therefore find the letter before waiting beside whichever ACTV shelter they see first.
If Burano is your destination, our guide to getting from Venice to Burano covers the rest of that journey.
Why your platform can change during the day
Dock assignments are not permanent promises. ACTV can alter them because of timetable changes, maintenance, crowd management or unusual navigation conditions. Fog, high water and major Venetian events can also produce temporary routing changes.
Even ordinary timetables may switch a route to another letter at a specified hour. Rialto and Ferrovia are good examples, with current stop maps explicitly showing evening changes for some departures.
This is why an old screenshot from a travel blog is useful for understanding the layout but poor evidence for tonight’s departure. Before a journey through one of the larger interchanges, check ACTV’s current maps of waterbus stops and then confirm the live information when you arrive.
The Italian words that make the signs easier to read
- Approdo: boarding dock or waterbus stop.
- Mappa degli approdi: map of the boarding docks.
- Partenze da: departures from.
- Per: to or toward.
- Imbarco: boarding.
- Uscita: exit.
- Ferrovia: railway station.
- P.le Roma: abbreviation for Piazzale Roma.
- F.te Nove: abbreviation for Fondamente Nove.
- Lido S.M.E.: Lido Santa Maria Elisabetta, the main Lido transport interchange.
The biggest trap is reading only the route number. If Line 2 appears twice on a board, the destination list beside each entry tells you which direction that departure is taking.
Do not confuse the platform letter with the stop name
A dock letter is one level below the actual stop. This distinction becomes important around San Marco, where names such as San Marco-Giardinetti, San Marco-Vallaresso and San Marco-San Zaccaria can appear in journey information.
Walking to “San Marco” is therefore not precise enough. First identify the named ACTV stop specified by your journey, then look for its lettered pontoon.
The same rule helps when organising several transfers in one day. Once you know which named stops you need, you can plan your Italy route around the walking sections instead of treating every vaporetto connection as if the boats arrived at a single central platform.
With luggage, strollers or reduced mobility
Get the letter right before approaching the boarding gate. Moving between pontoons can involve narrow waterfront paths, crowds and, at some locations, a surprisingly long walk.
ACTV requires luggage to be kept out of passageways and allows staff to restrict its transport if crowding creates a safety problem. On waterborne services, unfolded pushchairs and wheelchairs can be carried when crowding and safety conditions allow.
Some major docks also have separate boarding gates. Where ACTV’s priority system is installed, red gates marked PRIORITY VENEZIA UNICA are intended for eligible priority passengers, including passengers with reduced or impaired mobility, while black gates marked ALL PASSENGERS are for general boarding. The priority facility is available only at selected docks, not automatically at every letter within a stop complex.
Validate at the dock you actually use
Do not board first and plan to sort out the ticket later. ACTV says travel media must be scanned before accessing waterbus stops, and tickets must be validated again when changing service or vehicle. The current rules and fare information are published on the official ACTV urban services page.
If every validator at a waterbus stop is malfunctioning, ACTV’s transport conditions instruct passengers to ask the sailor to validate the ticket when boarding. A broken machine is not a reason simply to ignore validation.
What to do if you are waiting at the wrong letter
If you realise the error before the boat arrives, follow the public walkway to the correct pontoon. Do not climb barriers or try to use an exit gate as an entrance.
If the boat is already alongside another dock, resist the urge to sprint unless the route between the two is obvious and safe. At a place such as Fondamente Nove or San Zaccaria, the correct boarding point may be much farther away than it looks from the water.
If you miss the departure, check the board again before simply waiting for the next boat. The following service could use another letter, especially late in the day. Also check that you had the right direction in the first place. Boarding the correct line number in the wrong direction is one of the easiest ways to turn a five-minute wait into a tour of the Grand Canal you did not schedule.
The reliable habit is simple: stop name, line number, destination, letter. Read them in that order every time, even on a route you have already used earlier the same day.
