Ask Eurostat which is Europe's largest roll-on roll-off port and the answer for the third quarter of 2025 is Antwerp-Bruges, ahead of Rotterdam, Calais, Dublin and Lübeck. Ask a haulier and the answer is Dover, which handles around two million freight vehicles a year and does not appear in that table at all, because British ports left the European statistical series after Brexit.
Both answers are correct. That is the problem with ranking RoRo, and it is worse than the usual measurement argument because the three available units, freight units, tonnes and lane metres, disagree with each other about direction as well as size. In the last quarter of 2025 the United Kingdom counted more RoRo units and less RoRo tonnage than a year earlier, at the same time.
The busiest RoRo ports and freight ferry routes in 2026
| # | Port or route | Position | Latest movement |
|---|---|---|---|
| 1 | Antwerp-Bruges | Largest EU RoRo port, Q3 2025 | Up 4.2 percent year on year in the quarter, 3.3 percent across the first nine months |
| 2 | Rotterdam | Second EU RoRo port | Up 0.4 percent |
| 3 | Calais | Third EU RoRo port | Up 1.6 percent, handling between 1.6 and 1.8 million trucks a year |
| 4 | Dublin | Fourth EU RoRo port | Up 0.7 percent |
| 5 | Lübeck | Fifth EU RoRo port | Up 2.5 percent, the Baltic gateway in the top five |
| - | Dover | Outside EU statistics since Brexit | Around 2 million freight vehicles a year, up 88,000 units in Q4 2025 |
| - | Dover to Calais | Europe's busiest freight ferry crossing | DFDS and P&O pooled freight sailings from February 2026, a departure every 36 minutes |
| - | Dublin to Holyhead | Principal Irish Sea freight artery | 26 million tonnes of RoRo truck freight on the route pair |
Two things stand out in that list. The first is how tight the growth rates are: the entire EU top five moved within a band of 0.4 to 4.2 percent, which is a mature market redistributing rather than expanding. The second is that the largest single freight flow in the region sits between two ports where only one of them is being counted.
Units, tonnes and lane metres tell different stories
British port statistics for the fourth quarter of 2025 recorded RoRo freight tonnage down 2 percent to 20.9 million tonnes, while RoRo freight units rose 3 percent over the same period. The statisticians drew the obvious conclusion: more trailers and vehicles are moving, each carrying less.
I see the same effect in booking patterns. When retail demand softens but delivery frequency does not, hauliers keep the sailing and run the trailer lighter rather than consolidate and wait. The ferry operator books a full lane metre either way, so the operator's revenue holds while the shipper's cost per tonne climbs.
- Freight units count vehicles and unaccompanied trailers. This is the measure a ferry operator sells against, and it rose 3 percent.
- Gross weight counts what is inside them. It fell 2 percent to 20.9 million tonnes, and it is what your cost per tonne follows.
- Lane metres count deck space consumed, so a 13.6 metre trailer at half load and one at full load look identical to the vessel.
- Accompanied or unaccompanied changes the cost base entirely, because a driver crossing with the trailer is paid for the sailing while a dropped unit is not.
If you are benchmarking a RoRo lane year on year, compare cost per tonne rather than cost per unit, or the trend will look flat when your economics have moved.
Dover to Calais competes with a tunnel on the same corridor
The short strait is the only major freight ferry route in the world that shares its corridor with a rail shuttle carrying the same trucks. Le Shuttle Freight moved 1,163,124 lorries through the Channel Tunnel in 2025 and is holding that level: 104,032 lorries in July 2026, up 4 percent on July 2025, with 691,742 over the first seven months of the year, flat against the same period. Calais handles between 1.6 and 1.8 million heavy goods vehicles a year, and Dover around two million freight vehicles across all its services.
That competition changed the service pattern in February 2026, when DFDS and P&O Ferries agreed to let freight board the next available sailing operated by either company. The practical result is a departure roughly every 36 minutes instead of a wait for your own carrier's ship, which is the closest a ferry route has come to answering a fixed link on frequency. For a driver on hours, the choice now comes down to which queue is shorter on the day, and both modes publish live border waiting times because neither can afford a bad week at the frontier.
The border system is now part of the schedule
The European Union's Entry/Exit System went live on 12 October 2025, and freight drivers were in the first phase alongside coach passengers rather than in a later one. Nearly 13,000 traveller profiles had been created at Dover in the early months, accounting for around 30 percent of all registrations made across French seaports, and the border police have been running full compliance for freight at the tunnel sites since October.
Tourist car traffic is the part that has kept slipping. Rollout for cars was pushed into 2026 to avoid the Christmas period and has been phased since. For freight planning the practical read is that your drivers were enrolled in the first wave and the biometric step is behind you, while the risk of a general queue at the port stays open for as long as car processing is still being introduced alongside it. Our ranking of the busiest border crossings makes the same point on land frontiers: the throughput of a crossing is set by the slowest booth, not by the widest road.
The Irish Sea rebuilt itself around the customs line
Dublin's position as the fourth largest RoRo port in the European Union is a post-Brexit artefact. Nearly 500,000 articulated trucks were carried on Irish Sea ferry routes last year, and the Dublin to Holyhead pairing alone accounts for 26 million tonnes of RoRo truck freight. Direct continental sailings from Ireland grew sharply when the British land bridge acquired paperwork, then partly reverted once the process settled, which is why Dublin's 0.7 percent growth looks unremarkable next to Antwerp-Bruges.
Holyhead's storm damage over the winter of 2024 to 2025 forced a temporary schedule that hauliers then asked to keep, on the grounds that the revised pattern moved trade more smoothly than the old one. That is a useful reminder that ferry timetables are historical artefacts as much as commercial optimisations.
Where this fits with our other maritime rankings
RoRo freight and deep-sea vehicle shipping are separate trades that share terminology, so read this next to our ranking of the biggest car carriers and RoRo ships if what you are moving is vehicles rather than trailers.

Frequently asked questions
What is the busiest RoRo port in Europe?
Antwerp-Bruges led the European Union ports in the third quarter of 2025, followed by Rotterdam, Calais, Dublin and Lübeck. Dover handles around two million freight vehicles a year and would rank near the top on a like-for-like basis, but British ports are no longer counted in the European series.
What is the busiest freight ferry route?
Dover to Calais on the short strait, with a crossing of about 90 minutes. Since February 2026 freight can take the next available DFDS or P&O sailing under a pooling agreement, giving a departure roughly every 36 minutes. Calais alone processes between 1.6 and 1.8 million heavy goods vehicles a year, and the same corridor carried a further 1,163,124 lorries by rail shuttle through the Channel Tunnel in 2025.
Is RoRo freight growing?
In units, modestly. In tonnage, no. British ports recorded RoRo freight units up 3 percent and RoRo tonnage down 2 percent to 20.9 million tonnes in the fourth quarter of 2025, meaning more trailers carrying less each. Growth rates across the top five EU ports ran between 0.4 and 4.2 percent.
Does the EU Entry/Exit System delay freight?
Freight drivers were enrolled from the launch on 12 October 2025 and that phase has run without the disruption predicted for it, with Dover accounting for roughly 30 percent of registrations across French seaports early on. The unresolved risk is car traffic, whose rollout was deferred past the 2025 Christmas period and has been introduced in phases since, so port-wide queueing remains the variable to watch rather than the driver's own biometric step.
Should I book ferry or tunnel for a trailer?
Treat them as one capacity pool and choose on the day. The tunnel shuttle is faster in crossing time, the ferry gives more sailings and more resilience when one service fails, and both are hostage to the same border processing at either end. Hauliers running the strait regularly hold accounts with both for that reason.
Port rankings follow the European statistical office's quarterly series, which excludes United Kingdom ports and reports gross weight of goods rather than units, so a port's position can shift with the measure chosen. Dover and Calais vehicle counts come from the port authorities and mix accompanied and unaccompanied traffic. Quarterly British figures are provisional and subject to revision. Channel Tunnel shuttle volumes are the operator's published traffic. Entry/Exit System implementation dates have moved several times and apply differently to freight, coach and car traffic: confirm the current requirement for your drivers before dispatch.
