You’re standing on a windy pier in Anglesey, staring at a massive hunk of steel that's about to carry you across one of the busiest shipping lanes in the world. It’s a bit surreal. Most people think grabbing a ferry from Holyhead to Dublin is just a backup plan for when Ryanair prices get stupid or the liquid restrictions at security feel too oppressive. Honestly? They’re missing the point.
The Irish Sea isn't just a gap between two islands. It’s a mood.
Sometimes it’s a millpond. Other times, it’s a churning gray mess that makes you question your life choices and your breakfast. But if you know how to play it, this three-hour hop is actually the most civilized way to get to Ireland. You bring your car. You pack the "big" liquids. You don't have to deal with a middle seat next to a guy who doesn't understand personal space.
The Stena vs. Irish Ferries Rivalry
Basically, you’ve got two big players. Stena Line and Irish Ferries. They’ve been at each other's throats for decades, which is great for you because it keeps the ships looking halfway decent and the prices somewhat competitive.
Stena usually runs the Stena Adventurer and the Stena Estrid. The Adventurer is a bit of an old workhorse, but it’s sturdy. The Estrid is newer, sleeker, and feels less like a floating cafeteria and more like a modern hotel lobby. On the other side, Irish Ferries hits back with the Ulysses—which is legitimately one of the largest ro-pax ferries in the world—and the Dublin Swift, their fast craft.
If you’re prone to seasickness, here’s a tip: pick the Ulysses. It’s a monster. It’s so heavy it barely notices the waves that would have a smaller boat doing backflips. The fast craft (the catamaran) is great when the sea is flat, but if there’s even a hint of a gale, they’ll cancel it or it’ll feel like you’re inside a washing machine on the spin cycle.
Why Booking the "Club Class" Might Not Be a Scam
I used to think paying extra for the lounge was a total ripoff. I was wrong.

When you take the ferry from Holyhead to Dublin during peak season—think summer holidays or the Six Nations—the main decks are chaos. It's a sea of screaming kids, spilled orange juice, and people trying to sleep across three chairs. Spending the extra £20-£30 for the Stena Plus or Irish Ferries Club Class lounge gets you away from the madness. You get free coffee, snacks that aren't half-bad, and, most importantly, a dedicated power outlet.
Is the food in the lounge gourmet? No. It’s mostly crackers, fruit, and those little packs of biscuits. But the silence? That’s worth the entry fee alone.
The Logistics Nobody Tells You
Holyhead is a weird place. It’s the end of the line, literally. If you’re driving, give yourself way more time than Google Maps suggests. The A55 is notorious for "incidents"—usually a tractor or a breakdown in one of the tunnels—that can turn a smooth drive into a parking lot.
When you get to the port, have your passports ready. Since Brexit, things have gotten a bit more "official." You aren't just rolling onto a boat anymore; there are checks. It’s not quite the US border, but you can’t just wave a library card and expect to get through.
- Check-in times: If you’re a foot passenger, you need to be there at least 40 minutes before. Driving? Make it 60. If you’re five minutes late, they won't wait. They’ll shut that ramp and you’ll be stuck watching your boat sail away while you eat a sad sandwich in the terminal.
- Dog owners: You can keep your dog in the car (for free) or book a kennel. Some of the newer ships have "pet-friendly" lounges now, which is a game changer if you don't want your Golden Retriever judging you from the backseat for three hours.
The Midnight Boat: A Pro Move or a Nightmare?
There is a sailing that usually leaves around 2:00 AM or 3:00 AM.
It sounds terrible. It often is. But if you’re driving a long distance—say, coming from London or the South of England—it’s the only way to arrive in Dublin at dawn. You drive through the night while the roads are empty, roll onto the boat, grab a cabin, and pass out. You wake up seeing the Poolbeg chimneys (those big red and white stacks) and you’re in Dublin before the morning rush hour hits.

Just don't try to do it without a cabin. Trying to sleep on a lounge chair with the hum of the engines and the fluorescent lights is a special kind of purgatory.
Dublin Port vs. The City
One thing to keep in mind: Dublin Port is not in the city center. It’s an industrial wasteland of shipping containers and trucks. If you’re a foot passenger, there’s a bus (the 53 or special ferry links) that takes you to Busáras in the center. Don't try to walk it. It’s long, it’s ugly, and you’ll probably get lost behind a warehouse.
If you’re driving, the Dublin Port Tunnel is your best friend. It costs a bit more during rush hour, but it bypasses all the city traffic and dumps you right onto the M50 motorway. It’s the fastest way to get anywhere else in Ireland without losing your mind in Dublin’s one-way system.
Breaking Down the Costs
People always ask if the ferry is cheaper than flying.
Rarely. By the time you factor in fuel, the ferry ticket, and maybe a meal on board, a budget flight is almost always "cheaper" on paper. But that’s a false economy. If you’re moving house, going on a long road trip, or taking the whole family plus the dog and a roof box full of camping gear, the ferry from Holyhead to Dublin wins every single time.
You pay for the convenience of having your own stuff. No baggage scales. No "your bag is 2cm too wide" fines.

What to Actually Do on Board
Don't just sit there.
Go out on the deck when you're leaving Holyhead. The view of the Breakwater and the South Stack Lighthouse is genuinely stunning. Even if it’s freezing, go out for five minutes. It puts the scale of the journey into perspective.
Then, go to the shop. It sounds cliché, but the "Duty Free" deals are back after Brexit. You can actually save a decent amount on spirits and perfume, provided you don't get carried away and buy a giant Toblerone you didn't want.
Final Practical Advice
- Book in advance. If you show up at the gate hoping for a ticket, you’ll pay double. Or triple.
- Check the weather. Use an app like Windguru or Windy. If the wind is gusting over 40 knots, expect delays or a very bumpy ride.
- Motion sickness meds. Take them an hour before you board. Taking them once you’re already feeling sick is like putting on a seatbelt after the crash.
- Download your movies. The "free" Wi-Fi on ships is notoriously patchy. It works by satellite and as soon as everyone starts trying to stream Netflix, it dies a slow death.
The crossing is a ritual. It’s the transition from the rugged Welsh coast to the green chaos of Ireland. It’s slow travel in a world that’s way too fast. Treat it like a break in your journey rather than a hurdle to get over, and you'll find it's actually the best part of the trip.
If you're ready to book, head straight to the Stena Line or Irish Ferries official sites. Avoid third-party "comparison" sites that add hidden booking fees; they rarely offer a better deal than going direct. Once you've got your reference number, download the carrier's app for real-time gate and boarding updates, as Holyhead's terminal announcements can be hard to hear during the Friday afternoon rush. Make sure your vehicle's insurance covers you for the Republic of Ireland, and if you're planning to use the Port Tunnel on arrival, have your contactless card or small change ready for the toll booths.
