A hire car is the best way to see Ireland's scenery. Before you book: reserve an automatic early if you're not used to a manual, understand the insurance excess (typically €1,500–€2,000) before you arrive at the desk, drive on the left, and respect how narrow rural roads really are.
A hire car is the single best way to see Ireland. The country's most spectacular scenery — the Wild Atlantic Way, the Ring of Kerry, the Slea Head Drive, Connemara — sits well off the public transport network, and a car gives you the freedom to pull in at every viewpoint and reach the places the coaches can't.
But driving in Ireland comes with a few quirks that catch visitors out. This guide covers everything you need to know before you book, from manual vs automatic to the insurance trap that surprises almost everyone.
Do You Actually Need a Car in Ireland?
For Dublin and the bigger cities, no — they're walkable and well served by buses and trains. But for the scenery that draws most people to Ireland, a car is close to essential. Rural bus services are infrequent, and the best drives (Kerry, the west coast, Connemara) simply aren't reachable any other way.
If your trip is city-only, skip the car. If you want to see the coast and countryside — which is most of what makes Ireland special — rent one.
Compare hire cars across the major suppliers in one place, and add full excess cover when you book online rather than paying marked-up rates at the desk.
Compare car hire — coming soonManual vs Automatic
This is the big one. The vast majority of hire cars in Ireland are manual (stick shift). Automatics are available but more limited and noticeably more expensive, and they sell out first in peak season.
If you're not confident driving a manual — especially while also adjusting to driving on the left — pay the premium for an automatic and book it early. Learning to work a clutch on a narrow Kerry road with a stone wall on one side is not the introduction to Ireland you want.
Driving on the Left
In Ireland you drive on the left-hand side of the road, and the driver sits on the right of the car. For visitors from the US, mainland Europe and most of the world, this takes a little adjustment.
A few things that help: the gear stick is on your left (in a manual); roundabouts go clockwise, so give way to traffic coming from your right; it's easiest to make mistakes when turning into an empty road or pulling out of a car park, so take an extra beat at those moments; and take it slow for the first hour — it clicks faster than you'd expect.
The Insurance Trap (read this before you book)
This catches almost every visitor. The headline rental price includes a Collision Damage Waiver (CDW), but that waiver caps how much the company will cover — the portion you remain liable for is called the excess, and it's typically €1,500–€2,000 for a standard car, rising to €3,000 or more for premium SUVs and 7-seaters. If anything happens to the car, you're on the hook for that amount.
There's a second sting: if you decline the desk's excess-reduction cover, the company will place a pre-authorisation hold of around €5,000 on your credit card for the duration of the rental. You need that much available credit, on a card in the lead driver's name, or you'll be required to buy their cover anyway.
Your options:
• Buy the desk upgrade (Super CDW) — reduces the excess to zero. Simplest, but the most expensive, typically €12–€28 per day.
• Buy standalone excess insurance before you travel — far cheaper, often €3–€8 per day from a third-party provider, and it reimburses any excess you're charged. Note that many of these standalone policies are sold to Republic of Ireland residents; visitors should check eligibility before relying on one.
• Check your credit card or travel insurance — but be careful here: Visa cards generally offer no rental coverage in Ireland, most American Express cards exclude it, and many Mastercards do too. Ireland is one of the most commonly excluded countries, so never assume — get written confirmation from your card issuer that you're covered specifically in the Republic of Ireland.
Whatever you choose, decide before you arrive at the desk. Being presented with a high excess at the counter after a long flight is exactly when people overpay. If you do plan to buy standalone excess cover, it usually must be purchased before you sign the rental agreement, so sort it in advance.
Understanding Irish Roads
Irish roads are graded by letter, and knowing the difference helps you plan realistic driving times. M roads (motorways) are fast and modern, mostly around Dublin and between major cities. N roads (national) are the main routes between towns and are generally good. R roads (regional) are where the scenery is, and where roads get narrow — the Slea Head Drive is the R559. L roads (local) are often single-track with grass growing up the middle: beautiful, but slow.
The key thing for visitors: distances are short but journeys are slow. A 100km drive on regional roads can take well over two hours once you factor in the bends, the tractors and the views you'll want to stop for. Don't over-pack your daily itinerary.
Narrow Roads and What to Expect
Rural Ireland's roads are genuinely narrow — often barely wider than a single car, with stone walls or hedges right at the edge and no hard shoulder. Some scenic drives, like the Slea Head Drive and the Conor Pass, are particularly tight.
A few survival tips: drive the popular loops in the recommended direction (Slea Head clockwise, Ring of Kerry clockwise) to keep tour coaches behind you; use the pull-ins, where whoever is nearest waits or reverses and a friendly wave is standard; a smaller car is your friend on these roads, so resist the urge to upgrade to something big; and slow down — almost every visitor scrape happens by clipping a wall or hedge while going too fast.
Most rental insurance is voided the moment you take the car off a public tarmac road — and some policies specifically exclude routes like the Conor Pass where signs warn against rental cars. Stick to the sealed road, mind the "no rental cars" signage, and never drive onto a beach or forest track in a hire car.
Practical Booking Tips
Book well in advance for summer (June–August) and bank-holiday weekends — automatics in particular sell out. Pick up at the airport if you're driving straight out; Dublin, Shannon, Cork and Kerry airports all have rental desks. Bring your physical driving licence and the card — most visitors don't need an International Driving Permit, but check your country's requirements. Photograph the car thoroughly at pickup and drop-off — every existing scratch and dent — to protect against disputed damage charges. And refuel before returning to avoid steep refuelling fees.
Ready to Plan the Driving Routes?
Once you've sorted the car, the fun begins. Build your trip around the Slea Head Drive on the Dingle Peninsula and the Ring of Kerry — our 4 days in Kerry itinerary ties them together — then explore the wider Wild Atlantic Way along the entire west coast. A car turns Ireland from a series of stops into one continuous, unforgettable road trip — which is exactly how it's best seen.
Frequently Asked Questions
Do you need a car in Ireland?
Not for the cities, which are walkable and well connected. But for Ireland's best scenery a car is close to essential, as rural buses are infrequent.
Manual or automatic?
Most hire cars are manual. If you're not confident with a stick shift, book an automatic early — they're limited and sell out first.
What's the insurance excess?
Typically €1,500–€2,000 for a standard car, even with the included CDW. Decide how you'll cover it before you reach the desk.
