Day Trip to Belfast from Dublin — Trains, Buses, and What to Know

Belfast Is Two Hours Away — and Worth Every Minute

Belfast is the capital of Northern Ireland, which is part of the United Kingdom — not the Republic of Ireland. It sits on the same island, just two hours north of Dublin by train, but once you cross the border you are in a different country, currency included. The border itself is invisible — no passport checks, no queues — but you will notice that road signs switch to miles and the first shop you enter quotes prices in sterling.

How to Get There

• Enterprise Train (recommended): The intercity service between Dublin Connolly Station and Belfast Lanyon Place runs eight times a day in each direction. Journey time is 2 hours 10 minutes. Book at irishrail.ie or translink.co.uk. Advance fares start at €17 single and around €30 return if you book a week or more ahead. Walk-up price on the day is roughly €34 single. The train has Wi-Fi, power sockets, and a café car.
• Bus Éireann / Goldline Express: Runs from Dublin Busáras (the central bus station) to Belfast Europa Bus Centre, several times daily. Journey time is 2.5–3 hours. Tickets from €10 single when booked online in advance. Slower than the train but noticeably cheaper.

What to Bring

You do not technically need a passport to travel from Dublin to Belfast — there are no border checks between the Republic and Northern Ireland. However, always carry valid photo ID. If you plan to fly onward from Belfast to another destination, you will need your passport at check-in.

The most important thing to know before you go: Northern Ireland uses British pounds sterling (GBP), not euros. Many shops near the city centre tourist area accept euros, but at a poor exchange rate. Use a card without foreign transaction fees — Wise and Revolut are both ideal for this — or withdraw a small amount of GBP from a Belfast ATM when you arrive. Avoid currency exchange bureaus; their margins are bad.

What to Do in Belfast

• Titanic Belfast: A world-class museum built on the exact spot where the RMS Titanic was constructed. Adult ticket costs around £21. Book online to skip the entrance queue. Allow 2–3 hours inside.
• Cathedral Quarter: The best area for food and a drink. Compact, walkable, full of independent bars and restaurants. The Duke of York pub — narrow, covered in old whiskey advertisements — is the most atmospheric place to sit for a while.
• Political Murals and Black Taxi Tours: The famous murals in the Falls Road (republican) and Shankill Road (loyalist) areas tell Belfast's complex recent history. A guided black taxi tour costs around £15 per person and takes 90 minutes. It is one of the most memorable things you can do in Ireland.
• Victoria Square: A shopping centre with a glass dome that offers free panoramic views of the city from the top. No ticket needed to go up.
• St. George's Market: Open Friday to Sunday mornings. Fresh food stalls, local crafts, and live music. Free entry.

Getting Back to Dublin

The last Enterprise train from Belfast Lanyon Place to Dublin Connolly departs at around 20:00 on weekdays — check the exact time when you book, as it varies slightly by day. The last Goldline bus from Belfast Europa Bus Centre leaves around 21:00. Plan your day around these times and you will have a comfortable 10–11 hours in Belfast.
