Brittany is one of the few French regions you can reach either by a direct overnight ferry from the UK or by a short flight. That makes the choice a genuine one, and it is worth getting right, because the wrong mode can add cost, time and hassle that colours the whole holiday. This guide compares the two honestly, including the times when flying is clearly the better option.
THE SHORT ANSWER
Which mode suits your trip?
The table below sets out common traveller profiles and which mode tends to suit each. These are starting points, not absolute verdicts. The rest of the guide explains the reasoning behind each.
These are general tendencies, not guarantees. Your specific dates, destination and UK starting point always matter. Use the sections below to work through the factors that apply to you.
WHAT THE FERRY GIVES YOU
What taking the ferry gives you
The ferry's advantages are structural rather than promotional. They come from the fact that you are bringing your own vehicle and your luggage onto a ship, rather than fitting yourself into a flight.
Your own vehicle
You drive your own car onto the ferry and off the other side. No hire car paperwork, no adjusting to an unfamiliar vehicle, no mileage limits.
Luggage without limits
There are no baggage allowances or weight restrictions on the ferry. You can pack as much as your car holds, which matters for families, cyclists, surfers and self-catering stays.
Space and comfort onboard
Ferries offer restaurants, bars, decks and cabins. You can walk around, eat a proper meal and sleep in a bed rather than sitting in a single seat for the whole journey.
Pet options
Pets can travel in your vehicle, a kennel or a pet-friendly cabin depending on the ship and route. This is far more practical than the restrictions on flying with animals.
Direct arrival into Brittany
Portsmouth to Saint-Malo and Plymouth to Roscoff both arrive directly in Brittany. You step off the ferry already inside the region, with no onward flight transfer.
Flexibility once in Brittany
Having your own car gives you complete freedom to explore, which matters in a region where many of the best beaches, villages and coastal paths are not served by public transport.
WHAT FLYING GIVES YOU
What flying gives you
Flying has real advantages, and they are not just about speed. For certain trip shapes, flying is genuinely the better option, and it is worth understanding why.
Shorter travel time on short trips
A flight to Rennes, Nantes or Brest takes around 1-2 hours, compared with overnight ferry crossings. On a short break, that saved time can be the difference between a trip being worthwhile or not.
Useful for short breaks
If you are going for 2-3 nights, the ferry's overnight crossing each way can consume a significant portion of the trip. Flying can make a short break feel like a short break rather than a travel day.
Practical without a car
If you don't need a car in Brittany, flying avoids paying to transport one. This suits city-focused trips to Rennes or Vannes, or holidays where you plan to use local transport or stay in one place.
UK departure geography
Travellers in the South East can fly from Gatwick to Brest, Rennes or Nantes. Travellers in the North West can fly from Manchester to Rennes. For some, the drive to Portsmouth or Plymouth is longer than getting to a nearer airport.
Onward rail and car-hire options
Rennes, Nantes and Brest airports have car-hire desks and rail connections. If your destination is on a rail line, flying plus train can be a viable car-free option.
COST
Cost: how to think about it
It is not useful to publish fixed sample prices, because fares for both ferry and flight change constantly with season, demand, how far ahead you book, and the specific route. Instead, it is more helpful to understand the cost structure of each, because that is what determines which is cheaper for your specific trip.
Ferry cost variables: the vehicle fare, each passenger, cabin or seat reservation, season and sailing type, route choice, and fuel to and from the UK port. A family of five with a car splits the vehicle fare five ways, which is why the ferry becomes more cost-effective per head as group size grows.
Flying cost variables: each passenger pays a fare, baggage fees apply, airport transport or parking adds cost, car hire in France is often needed, and onward transport from the arrival airport may be required. A solo flyer pays one fare, which is why flying can be cheaper for one or two people.
A solo ferry passenger pays a vehicle fare plus a cabin, with no one to split it. A solo flyer pays a single fare. But a family of five on the ferry splits the vehicle fare five ways and takes unlimited luggage for free, while the same family flying pays five fares, five baggage fees, and car hire on arrival. The bigger the group and the more luggage, the more the ferry's cost structure works in your favour.
A solo traveller flying to Rennes for a city break will usually find flying cheaper. A family of five with a car and bikes heading to Carnac will usually find the ferry cheaper. Both can be true at the same time, which is why any claim that one mode is always cheaper is wrong.
TIME
Time: the honest maths
Comparing a flight duration against a ferry crossing duration in isolation is misleading. Neither number represents the actual time from your front door to your Brittany accommodation. The honest comparison is door-to-door, and it includes every stage.
Drive to Portsmouth or Plymouth, check-in (usually around 45-90 minutes before sailing), the crossing itself, disembarkation, and the onward drive in Brittany. The overnight crossing means you sleep through most of the sailing, but the total elapsed time from home to destination is still a full day or more.
Travel to your UK airport, arrive 2-3 hours before departure, the flight, baggage reclaim and exit, and onward transport from the arrival airport to your Brittany destination. The flight itself is short, but the surrounding stages add up.
The key insight is that flying may save substantial time on a short trip, because the flight itself is so much shorter than an overnight crossing. But the ferry arrives with your own car, which simplifies the onward journey, particularly if your destination is not near an airport or rail line. For a family heading to a coastal gite, the ferry's door-to-door time may be competitive once you account for airport procedures, baggage and car hire collection.
Verified current ferry crossing times: Portsmouth to Saint-Malo is an overnight sailing averaging around 11 hours, with evening departures and morning arrivals most days. Plymouth to Roscoff has overnight sailings averaging 8-11 hours most days, plus a daytime crossing of around 5 hours 15 minutes on Fridays. Schedules vary by season and tidal conditions, so always confirm current timetables with the operator.
WHEN FLYING MAKES MORE SENSE
When flying makes more sense
This section exists because an honest comparison must acknowledge where flying wins. If any of these describe your trip, flying is likely the better choice.
On a short break, the ferry's overnight crossing each way can consume a large portion of the trip. Flying can make a short break genuinely feel like a short break rather than two travel days bracketing one full day.
If you don't need a car in Brittany, flying avoids paying to transport one. This suits city breaks to Rennes, stays in Vannes or Saint-Malo where everything is walkable, or holidays where you plan to use local transport.
A solo ferry passenger pays a vehicle fare plus a cabin, with no one to split the cost. A solo flyer pays a single fare. For one or two people, flying can be more cost-effective, especially if booked in advance.
If you live near Gatwick, Stansted or Manchester, a direct flight to Rennes, Nantes or Brest can be quicker than driving to Portsmouth or Plymouth, crossing overnight, and driving on in France.
If your destination is near Rennes, Nantes or Brest, or on a rail line from one of them, flying plus onward train or a short car-hire can work well. This is particularly relevant for southern Brittany, where the ferry ports in the north and west add driving.
WHEN THE FERRY MAKES MORE SENSE
When the ferry makes more sense
If any of these describe your trip, the ferry is likely the better choice.
If you want or need your own vehicle in Brittany, the ferry is the only practical option. You drive on, drive off, and your car is part of the journey rather than a separate hire arrangement.
For families, the ferry's lack of baggage limits is a genuine advantage. You can pack pushchairs, bikes, surfboards and self-catering supplies without paying excess baggage fees or wrestling cases through an airport.
The ferry is by far the more practical option for pets. Depending on the ship and route, pets can stay in your vehicle, travel in a kennel, or share a pet-friendly cabin. Flying with pets is severely restricted and often impractical.
On a one or two-week holiday, the overnight crossing becomes a smaller fraction of the total trip. The convenience of having your own car in Brittany, with no hire paperwork or mileage limits, tends to outweigh the crossing time.
If you are staying near Saint-Malo, Dinan, Roscoff or the north coast, the ferry ports are right there. Arriving in Plymouth-Roscoff or Portsmouth-Saint-Malo means minimal onward driving for these destinations.
PETS
Travelling with a pet
If you are travelling with a dog, cat or ferret, the ferry is almost always the more practical option. Pets can travel in your vehicle, in a kennel, or in a pet-friendly cabin depending on the ship and route. Flying with pets is severely restricted and often impractical for a typical family holiday.
Since Brexit, UK pet travel requirements apply. Your pet needs a microchip, a valid rabies vaccination, and an Animal Health Certificate (AHC) issued by an official veterinarian within 10 days of travel. A new AHC is needed for each trip unless you hold a valid EU pet passport. For return to the UK, dogs require tapeworm treatment administered by a vet 24-120 hours before the return sailing. Always check the current requirements on gov.uk before travelling.
FERRY: WHAT NEXT?
If you decide the ferry is right
If the ferry is the better option for your trip, the next decision is which route suits your destination. The two direct routes arrive in different parts of Brittany, and that matters for your onward journey.
Arrives in eastern Brittany. Best for Saint-Malo, Dinan, the Emerald Coast, and onward travel to southern Brittany. Overnight sailings most days, averaging around 11 hours.
Arrives in western Brittany. Best for Finistere, the Pink Granite Coast, and western Brittany. Overnight sailings most days averaging 8-11 hours, plus a daytime Friday crossing of around 5 hours 15 minutes.
FLYING: WHAT NEXT?
If you decide flying is right
If flying is the better option for your trip, the next step is choosing your airport and onward transport. There are three airports that serve Brittany, and they suit different parts of the region.
Brittany's regional capital, in the east of the region. Direct UK flights from London Gatwick (EasyJet) and Manchester (EasyJet). Good for eastern and central Brittany, and a useful rail hub for onward travel.
Technically in the Pays de la Loire region but the main airport for southern Brittany. Direct UK flights from London Gatwick (EasyJet) and London Stansted (Ryanair). Best for Carnac, Vannes, the Gulf of Morbihan and the south coast.
In western Brittany (Finistere). Direct UK flights from London Gatwick (EasyJet). Best for western Brittany, the Pink Granite Coast and Finistere destinations.
Direct flight schedules can be seasonal, so always check current availability with the airline before booking. If you need a car in Brittany, all three airports have car-hire desks, but book ahead in peak season. If your destination is on a rail line, flying plus train can be a viable car-free option, particularly from Rennes.

BOTTOM LINE
The bottom line
Neither the ferry nor flying is the better way to reach Brittany. The better way is the one that fits the shape of your trip.
If you are taking your own car, travelling as a family or group with luggage, going for a week or more, heading to a destination near Saint-Malo or Roscoff, or travelling with a pet, the ferry is usually the better choice. It arrives directly in Brittany with your vehicle and your luggage, and its cost structure favours larger groups.
If you are travelling without a car, going for a short break, flying solo or as a couple, departing from near Gatwick, Stansted or Manchester, or heading to a destination near Rennes, Nantes or Brest, flying is often the better choice. It is faster on short trips and avoids paying to transport a vehicle you do not need.
The decision should start with your trip, not with a presumption that one mode is better. Work through the factors above, and the right answer for your specific holiday will usually become clear.
