Driving to Dublin Airport from Northern Ireland

For many travellers in Northern Ireland, Dublin Airport is the airport of choice: more routes, more long-haul flights and, often, better fares than Belfast. With around 36 million passengers in 2025, Dublin offers a far wider network than either Belfast airport. The drive is straightforward, almost entirely on motorway and dual carriageway, but crossing into the Republic brings a few practical differences: euro pricing, a motorway toll, speed limits in kilometres per hour and questions about insurance. This guide covers the route, journey times, the paperwork UK drivers need, and the best parking options at Dublin for drivers coming from the North.

The drive from Belfast to Dublin Airport is about 158 km (around 100 miles) and takes roughly 1 hour 35 minutes in good traffic, or about 2 hours with normal delays. The route follows the M1 and A1 via Newry, with one toll on the M1 near Drogheda costing €2.30 for a car in 2026.

UK drivers do not need a Green Card to drive in the Republic of Ireland, and a UK driving licence is valid. Parking at Dublin is charged in euro, so expect your card provider's exchange rate. For long stays, Express Red and Park2Travel are the most convenient options from the M1.

How Long Does It Take to Drive from Belfast to Dublin Airport?

Around 1 hour 35 minutes in light traffic and about 2 hours in typical conditions. The distance is about 158 km. Allow extra time for traffic around Belfast and Dublin at peak hours, and for the airport approach roads on busy mornings.

The Route: Belfast to Dublin Airport

1. Leave Belfast on the M1 southbound towards Lisburn and Sprucefield.
2. At Sprucefield, join the A1 towards Banbridge and Newry. The A1 is dual carriageway through to the border.
3. After Newry, cross into the Republic, where the road becomes the M1 motorway towards Dundalk and Dublin. Speed limits change to kilometres per hour.
4. Pass the M1 toll between Junction 10 (Drogheda North) and Junction 7 (Julianstown). The toll for a car is €2.30 in 2026, payable at the plaza.
5. Exit for Dublin Airport at the airport junction and follow signs to your car park. For Express Red, follow signs for the R132 and the Long Term Red Car Park. For Park2Travel, turn onto the Swords Road at the airport roundabout and follow the directions in our Park2Travel guide.

The route does not use the M50, so you do not need to pay the M50 barrier-free toll when driving to the airport from the North.

Do You Need a Green Card to Drive from Northern Ireland to Dublin?

No. Since 2 August 2021, UK drivers no longer need an insurance Green Card to drive in EU countries, including the Republic of Ireland. Your UK motor insurance certificate is sufficient proof of cover, though you should confirm with your insurer that your policy extends to driving in the Republic.

Paperwork checklist for UK drivers

If you are driving a hire car from Northern Ireland into the Republic, check with the rental company that cross-border travel is permitted and covered.

Paying in Euro

All parking at Dublin Airport is priced and charged in euro. When you book with a UK card, DAA notes that the exchange rate is applied by your card provider at the time of booking, and your bank may add a foreign transaction fee. A card with no foreign transaction fees can reduce the cost. The M1 toll plaza accepts card payment.

Where Should Northern Ireland Drivers Park at Dublin Airport?

Express Red and Park2Travel are the most practical long-stay options for drivers arriving on the M1: both are close to the motorway approach, have short shuttles and accept tall vehicles. Holiday Blue is cheaper but has a longer transfer. For early flights after a long drive, a hotel park and fly package removes the risk of a pre-dawn journey.

Compare all options in our guides to Dublin Airport long term parking, hotel parking and Dublin Airport parking. Book in advance: drive-up rates are €25 per day at Express Red and €20 at Holiday Blue, well above typical online prices. See parking without a booking.

Planning Your Departure Time

Combine the drive with DAA's terminal advice: 2 hours before short-haul flights and 3 hours before long-haul. For an 08:00 short-haul flight using Express Red, you would aim to reach the car park by about 05:20, which means leaving Belfast by around 03:30 to 03:45 to allow for the drive and a margin. See our guide on how early to arrive when parking.

Not Driving? Coach Alternatives

If you would rather not drive or pay for parking, direct coaches link Belfast with Dublin Airport around the clock:

• Aircoach 705X: Belfast to Dublin Airport, with departures 24 hours a day.
• Translink X1 and X2: the X1 stops at Banbridge and Newry; the X2 runs directly between Belfast and Dublin Airport, with frequent daytime services and early-morning departures.

Coach fares are typically a fraction of a week's parking, which makes them worth comparing for solo travellers. For groups and families, driving and parking usually works out cheaper and more flexible.
