Of all the ferry routes out of Portsmouth, the run to St Malo is the one that feels most like a proper voyage. You board in the evening, eat dinner as the Isle of Wight slips past, sleep in a cabin and wake up looking at the granite walls of a Breton corsair town. It is slower than flying, but it drops you and your car straight into Brittany with no airport in sight.

Who sails the route and how long it takes
Brittany Ferries is the only operator on the Portsmouth to St Malo route, and has been for decades. The crossing takes around nine hours in the daytime and closer to eleven hours overnight, and runs up to once a day in the summer, dropping to a few sailings a week in the quieter months. Most departures leave in the evening and arrive the next morning.
The headline facts are easy to hold in your head:
| Operator | Brittany Ferries |
| Crossing time | About 9 hours by day, 11 hours overnight |
| Frequency | Up to daily in summer, fewer in winter |
| Leaves from | Portsmouth International Port |
Where the ferry leaves from
Sailings go from Portsmouth International Port, on the western shore of the city just off the M275, not from the Historic Dockyard or the harbour railway station. It is well signposted from the motorway, has its own check-in lanes and offers paid parking if you are leaving the car in England and travelling as a foot passenger. Check-in usually closes a good while before departure, so give yourself time.
If you are driving on, follow the port signs rather than the city-centre ones, as the two lead to very different places.
Day crossing or overnight?
The choice between a daytime and an overnight sailing shapes the whole trip, so it is worth thinking about before you book:
- the overnight sailing saves you a hotel night and lands you in France fresh in the morning, but you will want a cabin to sleep properly;
- the daytime crossing is cheaper and fine with a reclining seat, though it uses up a whole day of your holiday;
- cabins are limited and sell out first in summer, so book one early if you want the overnight option.
For a week or more in Brittany most people take the overnight boat out and sleep on board, treating the crossing as the first night away.
What it costs
Brittany Ferries prices move with demand, the season and how far ahead you book, so treat any figure as a ballpark and confirm a live quote before you commit. As a rough guide a foot passenger can cross from somewhere around 50 to 90 pounds one way in quieter periods, while a car with a couple of people usually starts near 130 pounds and climbs steeply in peak summer. A cabin on the overnight boat is an extra charge on top, often adding 60 to 120 pounds depending on the type, and is effectively required if you want to sleep properly.
The usual tricks apply if you want to keep the cost down: book as early as you can, avoid the school holiday peaks, and look at midweek rather than weekend departures.
Arriving in St Malo
St Malo earns the slow journey. The old town, the intra-muros, is a tight grid of tall granite houses wrapped in sea walls you can walk right around, with wide tidal beaches on the other side. The ferry terminal is close to the walls, so foot passengers can be inside the old town within minutes of stepping off.
It also makes a brilliant base. Dinard sits across the estuary, the oyster town of Cancale is a short drive, and Mont Saint-Michel is close enough for a day trip. One regular traveller summed up the appeal.
You step off the boat and you are already on holiday, there is no transfer, no airport, you just walk into the old town and find breakfast.
That ease, as much as the town itself, is why people keep choosing the boat.
Is it worth it?
If you are carrying a car, a bike or more luggage than a plane allows, the St Malo ferry is hard to beat: you trade a few hours for a comfortable, scenic arrival right in the heart of Brittany. Book early for a summer cabin, pack for an overnight stay on board, and the crossing stops being a chore and becomes part of the trip.
