Departure times

Read the arrival column before you book anything on the far side. The Friday 23:59 out of Rosslare does not reach Spain on Saturday; it reaches Spain on Sunday morning, after 31 hours and two nights. Time zones make the clock lie in the other direction too, because Spain is an hour ahead of Ireland, so the Wednesday sailing that looks like 28 hours 30 on paper is 27 hours 30 in the water. Those durations are not our arithmetic: Brittany Ferries’ own pricing feed returns a UTC timestamp beside each local time, and they were checked one by one. Two wrinkles. The winter timetable drops the Wednesday daytime sailing entirely, leaving one departure a week from Ireland between 6 November 2026 and 19 March 2027, with a single Tuesday exception on 1 December 2026 at 09:00. And there is nothing at all over Christmas: the last Friday sailing of 2026 leaves on 18 December and the next one on 8 January 2027, a gap of three weeks. The published timetable gives the Thursday arrival at Rosslare as 20:15 while the booking engine returns 20:30 on 2026 dates and 20:15 on 2027 dates; the tidal caveat covers a good deal more than fifteen minutes, so treat the evening as approximate.

What it costs

Both columns are lead-in prices from Brittany Ferries’ own booking engine, queried on 5 August 2026, and they are not the same product. Brittany Ferries sells this route on a three-rung ladder: on the dates tested, Standard sat €40 above Economy and Flexi €50 above it. By August the Economy rung had already gone on the peak sailings, so the right-hand column is the Standard fare, which was the cheapest thing still bookable. Three things fall out of the numbers. A car effectively carries two people free: the second adult added €3, while the third and fourth added €63 each. Children are not discounted at all on this route, and the engine proves it: a car with two adults and one child priced identically to a car with three adults, at €218. And the car itself is cheaper than it looks, because €155 for a car and two adults against €88 for the same two people on foot puts the vehicle at €67 each way. That last figure is our arithmetic on the operator’s prices, not a published rate. Across every remaining 2026 sailing we priced, a car with two adults ran from €155 in October to €426 on Friday 7 August out of Rosslare, and to €556 coming the other way on 6 and 16 August.

Route map

South out of Wexford, down the Celtic Sea and straight across the width of the Bay of Biscay to the Basque coast, with the Spanish landfall at Zierbena rather than at Bilbao itself.

Accessible travel

Adapted cabins exist on the ships that work this route. Santoña carries wheelchair-accessible two-berth cabins in both inside and outside grades, fitted with an alarm and a telephone, and her sisters Galicia and Salamanca publish downloadable accessibility guides with deck plans. Both Irish and Spanish terminals are described by the operator as wheelchair accessible with disabled toilets, and Bilbao has designated disabled parking bays.

Then there is what the booking engine says, which is bleaker. We queried every Rosslare–Bilbao departure listed for 2026 and 2027, outbound and inbound alike. The accessible-cabin flag returned available on a single date: Wednesday 9 September 2026, outbound. The likeliest reading is that they are booked out, not that they are missing, which is an argument for phoning months ahead instead of trusting the website.

The most consequential thing Brittany Ferries publishes is a cap, and it publishes it plainly. Assistance must be notified when you book and again at ticket check-in. To meet safety rules the company “may have to limit the number of passengers needing individual assistance on each crossing”, and it may decline a booking where it has already reached the limit of disabled passengers it can carry safely, and will then put you on another sailing or refund you. It also recommends travelling with an able-bodied companion because of how the ships are laid out. On a route with one departure a week from Ireland in winter, “an alternative sailing” means seven days later. The Irish assistance and booking line is 021 427 7801. Brittany Ferries does not publish a required notice period for this route, a count of adapted cabins per ship, or any port-side boarding-lift arrangement at Rosslare, and we could not establish them from any other official source.

Sailing conditions

The tide moves the clock. Brittany Ferries prints the warning on its own timetable page: all times are local, departures and arrivals may vary by up to an hour with tidal conditions, and timetables are subject to change. On a crossing this long an hour is noise, but it is enough to lose a connection at the far end.

The Bay of Biscay is the other variable, and it has a reputation earned on the continental shelf edge, where the water goes from shallow to very deep in a short distance. We found no operator statement quantifying cancellations or rough-weather diversions on this route, so there are no numbers here. Absence of a figure is not absence of weather.

What the deep water does produce is wildlife. Brittany Ferries states that over a third of the world’s roughly ninety cetacean species have been recorded in the Bay of Biscay, and it has worked with the marine charity ORCA for years, putting trained wildlife guides aboard and selling Sea Safari crossings that list fin whales, sperm whales, Cuvier’s beaked whales, orca, minke whales, common and Risso’s dolphins and harbour porpoises among the species seen. One honest caveat, because it matters if you are booking for this reason: the Brittany Ferries page advertising the Rosslare–Bilbao Sea Safari at €199 was still showing 2025 departure dates when we checked on 5 August 2026, and ORCA’s own 2026 Sea Safari list carries only Plymouth departures. An Irish 2026 date is not confirmed by either party. The whales are there whether or not a guide is.

Cars and bikes

Here is the comparison that actually decides this route, and it is not against another ferry. Getting an Irish car to northern Spain means choosing between one long sea crossing and one short one followed by a very long drive.

On Wednesday 7 October 2026 the direct sailing to Bilbao was €155 for a car and two adults, plus a compulsory cabin from €114: €269 all in, 27 hours 30 at sea. The same day, the same car and the same two people to Cherbourg was €182 plus a cabin from €67, so €249, and 17 hours at sea. Twenty euro cheaper. It also leaves you at the tip of the Cotentin peninsula with 1,048 km to Zierbena, which routing on OpenStreetMap data puts at about 11 hours 20 minutes of driving before you add breaks, French motorway tolls, diesel or a night in a hotel. That distance and time are our own calculation, not an operator figure. Everything else in this paragraph came from the booking engine.

Two wheels are the bargain. A bicycle and rider cost €50 on that October Wednesday, six euro more than the same person walking on, and a motorbike and rider €77. Both climb steeply in August, to €140 and €173. Vans and minibuses could not be priced at all through the engine on any date tested, which is not the same as saying they are refused; ring the operator.

Pets travel, and the ships decide the terms. Adding one animal to a car booking on 7 October took the fare from €155 to €210, so €55 for the animal. Aboard Santoña there are large and small kennels, pet-friendly four-berth cabins inside and outside with laminate flooring and room for a standard animal bed, and a pet exercise area. There is also a flat prohibition worth knowing before you book: the operator rules out leaving an animal in your car aboard that vessel, and that any dog out of its cabin or off the car deck must wear a muzzle, ashore in the port as well as aboard. Check-in with an animal is 90 minutes, not 45.

Before you board

The national railway company owns Rosslare Europort outright, and that ownership shows in the layout: trains come inside the gates rather than terminating short of them. On a 27-hour crossing the terminal matters less than it would on a short hop, since you will spend more time on the ship than on either country’s roads that day. Get the check-in right and the rest looks after itself.

• The desk shuts 45 minutes ahead of sailing. Bring an animal and that becomes 90. That means 08:15 for the Wednesday 09:00. It also means 23:14 for the Friday 23:59, which is the one to plan around: a late-night arrival at a port at the end of the N25, with nothing open behind you.
• Parking is APCOA’s and it is cheap. €1 an hour, €3 for three hours, €5 for 24 hours, €25 a week, €50 a fortnight, €75 for three weeks. An annual permit is €700. The operator counts 335 spaces there.
• Worth doing the sum before you drive on. Two weeks in the car park is €50. On the 7 October prices, taking the car instead cost €67 each way, so about €134 return plus the extra fuel at the Spanish end. That is our arithmetic on the operator’s fares, and it moves with the date.
• The pay machines are gone. According to the port authority they have been decommissioned, leaving three ways to pay: the APCOA Connect site, its app, or a QR code stuck up somewhere at the port. Meanwhile the operator’s Rosslare page continues to promise cash and card. Trust the port, and arrive with a phone that has data on it.
• By train. Rosslare Europort station is inside the port itself, ten minutes on foot from the terminal by the operator’s reckoning. Trains here work the line up to Dublin Connolly, quoted at as many as five a day and under three hours end to end. No train times appear on this page, deliberately: Irish Rail’s own PDF timetables would not open.
• By bus. Brittany Ferries lists Bus Éireann routes 40, 132, 370 and 379 plus TFI Local Link 387 as serving Rosslare Harbour. In practice the two that matter are the 387 from Wexford and the 370 from Waterford. Neither operator’s timetable could be read, so no departure times are given here. More context in buses in Wexford.
• The same quay serves three other routes. France is Rosslare to Cherbourg; Wales is Rosslare to Fishguard and Rosslare to Pembroke Dock. Bilbao is the long one by a wide margin.

On the other side

You do not dock in Bilbao. The berth is at Zierbena, on the western side of the Nervión estuary in Bizkaia, and Brittany Ferries measures it at 21 km from Bilbao city, roughly twenty minutes by car. Postcode 48508. Nothing about the arrival feels like arriving in a city, because you have not.

That distance is the single most useful thing to know before you sail. A driver is past Bilbao within the twenty minutes the operator quotes; a foot passenger is standing on an industrial quay 3 km from the nearest metro station. The two experiences of this route diverge at the bottom of the vehicle ramp, and the operator’s own port page is candid about it, listing a taxi rank number in Santurtzi as the practical answer.

What the crossing buys you, in the operator’s own framing, is the Basque Country, northern Spain and south-west France without touching the United Kingdom or the French motorway network. Bordeaux, Pamplona, Santander and the Pyrenees all sit within a few hours of the ramp. So does Portugal, if you have the stamina.

Worth knowing

Can you do it in a day?

No, and not close. What you can do is something stranger, and Brittany Ferries sells it deliberately.

The tightest possible round trip uses the Wednesday out and the Thursday back. Leave Rosslare at 09:00 on the Wednesday, dock at Zierbena at 13:30 on the Thursday, and the ship you arrived on sails again at 18:00. Deduct the 45-minute check-in and you have three and three-quarter hours in Spain for two nights at sea. You would be back at Rosslare at 20:15 on the Friday.

The Friday version is longer at sea and shorter ashore. Out at 23:59 Friday, into Zierbena at 08:00 on Sunday, and the next departure from Bilbao is 11:00 that same morning. Three hours ashore, three nights aboard. That is not a scheduling accident: Brittany Ferries packages exactly that rotation as an ORCA Sea Safari at €199 per person for two sharing a four-berth inside cabin, sold as a foot-passenger return with three nights of en-suite accommodation and a donation of €60 to the marine charity. Read the small print on dates before you get excited; see the weather section below.

For an actual holiday, the useful pattern in the summer timetable is Wednesday out and Sunday back, or Friday out and the following Thursday back. In winter, with one departure a week from Ireland, your options collapse to multiples of seven days.

Onward travel

• Zierbena is 21 km from Bilbao and about twenty minutes by car, on Brittany Ferries’ own reckoning. Everything below is the foot passenger’s problem, not the driver’s.
• The nearest metro station is Santurtzi, which the operator puts at roughly 3 km from the terminal and calls a five-minute taxi ride. There is no published walking route from the quay, and an industrial port road is not a walk we would recommend on spec.
• The taxi rank has a phone number. Brittany Ferries lists Parada de Taxis de Santurtzi on +34 94 461 03 56, which is the number to have saved before you arrive at 08:00 on a Sunday.
• A shuttle bus exists. The operator says a bus run by the Port of Bilbao goes from the terminal to near the Guggenheim museum, and gives the city stop as what3words ///slimmer.usual.discrepancy. It publishes no times and no fare, and we could not find either on a port source. Ask at the terminal desk.
• Parking at the Spanish end covers short stay, long stay and overnight, with disabled bays and spaces for caravans and motorhomes. Terminal facilities are thin: a snack bar, Wi-Fi, wheelchair access and disabled toilets.
• Bilbao’s main railway station is at Plaza Circular 2, in the city rather than at the port, so any onward train means covering those 21 km first. We publish no Spanish rail or metro times here because we could not open an official Basque source for them.

Booking

The cabin is not an upgrade on this route. We priced Rosslare–Bilbao departures in both directions over two seasons, and the operator’s engine returned the same flag on all of them: accommodation mandatory. Budget for it as accommodation, because that is what it is: on the Friday sailing you are asleep on that ship twice. Lead-in cabin prices ran €114 in October 2026, €144 in spring 2027 and €169 at the August peak, quoted per cabin rather than per head.

Sellouts are real and they are not confined to August. Of the 2026 sailings we priced for a car and two adults, seven came back full: 13 and 28 August, 4, 11, 18, 20 and 27 September. Reclining seats went earlier still, with the seat allocation showing as gone on five more dates in late August and early September. This is a two-a-week route in high season and a one-a-week route from Ireland in winter, so a sold-out sailing does not cost you a few hours. It costs you three days.

Season shape matters more than the day of the week here. The Wednesday daytime sailing runs until 28 October 2026, disappears for the winter, and comes back on 24 March 2027 with Salamanca in place of Santoña, then continues to 3 November 2027. When it started in 2026 we cannot tell you, because the operator’s feed drops sailings once they have gone. The Friday night sailing runs all year, passing from Santoña to Galicia on 6 November 2026 and to Salamanca on 8 January 2027. Brittany Ferries’ Irish booking and assistance line is 021 427 7801.
