How to Get From Belfast to Dublin, Ireland
Trying to figure out how to get from Belfast to Dublin?
I’ve got you!
I have several, short and sweet directional guides to help you plan a trip.
While Google Maps and Apple Maps are great, you can’t always the aps blindly.
I’ve turned up to train stations and buses before just to find them closed for the day!!
Weather can impact operations, too – especially if you’re taking the train.
So be sure to keep an eye on the weather, and whichever app you use to book your ticket – if you’re not driving yourself.
Take it from someone who’s been to Ireland at least six times as of when she’s writing this – you want tips from someone who’s done this before.

First, a Quick Geography Note
If you’re not familiar with Irish geography, here’s the short version: Belfast is in Northern Ireland (part of the UK) and Dublin is in the Republic of Ireland (an independent country).
There’s an open border between the two, so you won’t be showing your passport at the crossing, but you are technically traveling between two countries.
Also, Northern Ireland uses pounds sterling (£) while the Republic of Ireland uses euros (€).
Most ticket prices for Belfast–Dublin routes are listed in both currencies, but it’s worth keeping in mind for cash purchases.
Your Main Options for Getting From Belfast to Dublin
1. By Train – The Fast and Scenic Choice
The train between Belfast and Dublin is called the Enterprise Service, jointly operated by Translink (NI Railways) and Irish Rail.
- Time: Around 2 hours 15 minutes
- Frequency: Every 2 hours during the day
- Cost: Around £17–£30 / €20–€35 one-way, depending on how early you book
- Booking: Book online at Translink or Irish Rail
- Tip: The earlier you book, the better the price. Sit on the left side when heading south for coastal views leaving Belfast.
This is the easiest, most stress-free option, especially if you like a little legroom and the ability to grab a tea from the onboard café.
2. By Bus – The Budget-Friendly Option
Two main companies run coaches between Belfast and Dublin: Aircoach and Translink’s Goldline Express. Both also have services directly to Dublin Airport if you need to fly.
- Time: Around 2 hours 30 minutes
- Frequency: Every 30–60 minutes
- Cost: Around £10–£15 / €12–€18 one-way
- Booking: Aircoach or Translink
- Tip: Coaches can get delayed if traffic is heavy, so avoid peak commuting hours if possible.
The bus is cheaper than the train and still very comfortable—especially the Goldline’s double-deckers with Wi-Fi.
3. By Car – The Road Trip Option
If you’re already renting a car, the drive is straightforward and gives you the freedom to stop along the way.
- Time: Around 2 hours via the M1 motorway
- Border Crossing: No checkpoints, but you’ll notice road signs switching from miles to kilometers as you cross into the Republic
- Tip: If your rental car is from Northern Ireland, make sure the company allows you to take it into the Republic. Most do, but some require an extra fee.
Driving gives you the flexibility to stop in charming towns like Drogheda or explore the Mourne Mountains on the way.
4. By Private Transfer – The Door-to-Door Option
If convenience is the top priority (or you’re traveling with a lot of luggage), a private transfer can take you directly from your Belfast accommodation to your Dublin destination.
I’ve never done this personally, but I have arranged this for clients.
Here’s what you can expect:
- Time: 2–2.5 hours, depending on traffic
- Cost: From around £200+ depending on group size and provider
- Tip: Works out more affordable if you’re traveling as a small group.
Which Option Should You Choose?
- Want speed and comfort? Take the train.
- On a budget? Hop on a bus.
- Want flexibility? Drive yourself.
- Want zero hassle? Book a private transfer.
Final Travel Tips
- Always check timetables in advance.
Irish public transport sometimes changes schedules for holidays or events. - If you’re renting a car, avoid driving in the city center.
Choose a car rental return just outside of Dublin, then take public transportation the rest of the way. - If traveling by train or bus, book online to guarantee your seat.
This is especially true throughout the summer, the week of St. Patrick’s Day, and during local festivals. - The currency changes between Northern Ireland and Dublin.
Keep both pounds and euros handy if you’re paying cash for snacks or tickets.
