Overview
So. You're planning a trip to Spain. And somewhere along the way, someone probably said "just fly." Quick. Cheap. Done. But—and this is a big one—flying isn't always the smartest move. It’s not, especially when you've got a car boot full of luggage, a dog that can't go in the cabin, or a family that genuinely dreads airport queues at 4am. The ferry to Spain from the UK is a different kind of travel. Slower, yes. But different in all the right ways.Brittany Ferries has been running these crossings for decades now, connecting the UK to Spain with routes that genuinely change how people think about getting there. You board, you settle in, you sleep—and you wake up somewhere close to where you actually want to be. No rental car hassle. No baggage fees that mysteriously double at check-in. No one is telling you your shampoo bottle is 15 ml over the limit.
Why the Ferry to Spain from the UK Deserves a Second Look
Here's the thing people don't always factor in when comparing travel options: the total cost and the total experience. Flying looks cheaper on paper. But add up airport parking, luggage fees, hire car costs, and the sheer misery of a budget terminal at 5am—and the numbers start to shift.With the ferry to Spain from the UK via Brittany Ferries, you're looking at a different equation entirely. Your car travels with you. Your bags don't have weight limits that send you into a panic at the check-in desk. And the crossing itself? It’s not wasted time. It's part of the trip.
Brittany Ferries operates some genuinely comfortable ships on these routes. Think cabins with real beds, restaurants, sea views, and—on certain sailings—even a spa. It's not a budget crossing. And it’s not meant to be. It's for people who want to arrive in Spain without feeling like they've already run a marathon.
And for road trippers specifically? There’s really no comparison here. You drive on, you drive off, and you're already in Spain with your own vehicle, your own schedule, and none of the hassle of picking up a rental car from a confusing lot outside Bilbao airport.
Portsmouth to Bilbao Ferry: The Classic Route
If you haven't looked into this one, you should. The Portsmouth to Bilbao ferry is probably Brittany Ferries' most iconic Spanish crossing—and for good reason. Portsmouth is easy to reach from a huge chunk of England. And Bilbao? It puts you right on the edge of the Basque Country, with the whole of northern Spain laid out in front of you.The sailing time is roughly 24 to 35 hours depending on the specific crossing. It’s longer on some days and a bit shorter on others. But here's what that actually means in practice: you board in the evening, you have dinner, maybe a drink at the bar, and you sleep in a proper cabin with a real pillow—and you're waking up somewhere over the Bay of Biscay with Spain approaching on the horizon.
Cabins on the Portsmouth to Bilbao ferry range from basic inside rooms to proper en-suite options with a porthole. In peak summer, it's worth booking a better cabin. You'll use it. The crossing is long enough that a decent night's sleep genuinely matters, and the difference between a cramped bunk and a proper bed is noticeable after the first hour.
The Bay of Biscay has a reputation—rough in winter, calmer in summer, and rarely boring. Pack seasickness tablets if you're sensitive to motion. No shame in it. Most people are fine; some aren't. Better to have them and not need them.
Portsmouth to Santander Ferry: The Other Option Worth Knowing
Right. So Bilbao isn't the only Spanish port in Brittany Ferries' network. The Portsmouth to Santander ferry is another option, and for people heading to central or southern Spain, it can actually be the smarter choice geographically.Santander sits slightly further west along the coast, which can shave meaningful time off your drive if you're heading towards Madrid, Salamanca, or anywhere in that direction. The ferry experience itself is comparable to the Bilbao route — similar ships, similar facilities, similar crossing times.
There's a version of this route that departs from Plymouth too. Worth checking both departure points depending on where in the UK you're starting from. Someone driving from Cornwall or Devon will obviously have very different preferences to someone coming from Yorkshire.
The crossing time on the Portsmouth to Santander ferry is typically around 24 hours, give or take. And again—it's not wasted time. That's a full day at sea, with food, rest, maybe some reading, and maybe some staring at the Atlantic, wondering what exactly a gannet is doing out this far. Normal ferry things.
How Long Is the Ferry from UK to Spain?
Fair question, and one that comes up constantly. So let's be clear about it.How long is the ferry from the UK to Spain? It depends on the route:
- Portsmouth to Bilbao: approximately 24–35 hours sailing time
- Portsmouth to Santander: approximately 24 hours
- Plymouth to Santander: roughly similar, around 20–24 hours depending on conditions
The key mindset shift is this: stop thinking of the crossing as travel time and start thinking of it as transition time. You're not sitting in a departure lounge. You're on a ship, moving through the ocean, with things to do and places to sleep. It's genuinely different.
Where the Ferry Wins: Luggage, Pets, and Big Loads
Okay, this section is important. Because this is where the ferry doesn't just match flying — it absolutely beats it.Luggage: No weight limits on your car boot. Bring the hiking gear, the surfboards, and the six bottles of wine you bought last time and swore you'd bring home this time. Your car is your luggage compartment. Fill it.
Pets: Brittany Ferries has proper pet-friendly facilities. Dogs can travel in kennels on board, with owners able to visit during the crossing. Some cabins are even pet-friendly, meaning your dog doesn't have to spend the whole journey alone below deck. Try doing that on a Ryanair flight.
Bikes and sporting kit: Cycling in Spain has become hugely popular. And if you've ever tried to bring a bike on a plane—the boxes, disassembly, and extra fees—you'll appreciate being able to simply roll it onto a ferry.
Large families or groups: Flying a group of five or six gets expensive fast, especially with luggage. The ferry economics can work out significantly better overall when you factor in the car and everything in it.
The Comfort Question: Honestly, How Good Is It?
Honestly? Better than most people expect. Brittany Ferries' ships on the Spanish routes—vessels like the Cap Finistère and Pont-Aven—aren't the old roll-on-roll-off ferries people sometimes imagine. They have restaurants with actual menus; bars; shops; cinemas on some sailings; and cabin standards that compare well to a decent mid-range hotel.Is it a cruise ship? No. Are you going to feel like you're on one? Surprisingly, sometimes yes. The observation decks alone are worth something — there's a particular kind of quiet on the open Atlantic that you simply can't get anywhere else.
The food on board has improved significantly. There's usually a self-service cafeteria option and a more formal restaurant. Breakfast before arrival is genuinely a nice moment—coffee, eggs, and watching Spain come into view through the windows. It sounds small, but it isn’t.
Road Trips from the Ferry Port: Why It Makes Sense
Bilbao and Santander are both excellent starting points for a Spanish road trip, which is probably the strongest argument for taking the ferry in the first place. You arrive, you drive off, and you're immediately in some of the most scenic driving territory in Europe.From Bilbao: the Basque coast, San Sebastián, the Rioja wine region, Burgos, and the road south towards Madrid are all accessible within a few hours.
From Santander: head west towards Asturias and Galicia or south through Cantabria towards the meseta.
Northern Spain, in particular, is underrated. It's green; it's mountainous; it's quieter than the south in summer, and the food—the pintxos in the Basque Country alone—is reason enough to make the journey. Arriving by ferry puts you right in the middle of it without having to touch an airport or a hire car desk.
Final Thoughts
The ferry to Spain from the UK isn't for every trip. But for the right kind of trip—a road journey, a family holiday, a pet-friendly escape, a proper adventure through northern Spain—it's hard to beat. The Portsmouth to Bilbao ferry and the Portsmouth to Santander ferry both offer something that flying simply can't: you arrive relaxed, with your own car, your own stuff, and none of the airport fatigue.Brittany Ferries has been making this crossing work for a long time. The ships are comfortable, the routes are well-established, and the experience of waking up at sea with Spain on the horizon is—genuinely—something worth doing at least once. Maybe more than once.
If you're weighing it up, check the dates, compare the real costs including your car and luggage, and think about what kind of holiday you actually want. The answer might surprise you.

FAQs
Can I bring my car on the ferry to Spain from the UK?
Yes. Brittany Ferries allows vehicles on all Spanish routes. You drive on at departure and off at arrival. It's one of the main reasons people choose the ferry.
Do I need a passport for the UK to Spain ferry?
Yes. Since Brexit, UK citizens need a valid passport to enter Spain. Check that it has at least six months' validity remaining.
Can I take my dog on the Portsmouth to Bilbao or Santander ferry?
Yes — Brittany Ferries has pet-friendly options including kennels and some pet-friendly cabins. Book early during peak season as these spaces are limited.
Is the Bay of Biscay rough?
It can be, especially in autumn and winter. Summer crossings are generally calmer. Motion sickness tablets are a sensible precaution if you're unsure how you'll handle open water.
How far in advance should I book?
For summer sailings, especially July and August, book several months ahead. Peak crossings fill up — particularly if you need pet-friendly cabins or specific cabin types.
Is the ferry more expensive than flying?
For a single traveller with no luggage, flying is often cheaper. For families, couples with a car, pet owners, or anyone with significant luggage, the ferry frequently works out better value once all costs are included.
