Before you go: the Northern Ireland basics
Belfast is in Northern Ireland, which is part of the United Kingdom — a different country and a different currency from the Republic of Ireland. When you cross from Dublin into Northern Ireland, you’ll notice:
Currency change: Northern Ireland uses GBP (British pounds sterling), not euros. Dublin is EUR; Belfast is GBP. Euros are accepted in some tourist-facing businesses in Belfast, but at unfavourable exchange rates. Bring GBP, use a multi-currency card (Revolut, Wise), or withdraw from a Belfast ATM.
Entry requirements: There’s no passport check or border control between the Republic and Northern Ireland — you cross freely. However, US citizens travelling from Dublin to Northern Ireland currently require a UK ETA (Electronic Travel Authorisation, currently £10, valid for 2 years). Check the Ireland entry checker for your nationality.
Time zone: Northern Ireland is on the same time as the Republic (and the UK) — no change.
Phone: Your EU roaming deal (if you have one) covers the Republic but not Northern Ireland. Check roaming costs for UK before you travel.
Option 1: Enterprise train — the best experience
The Enterprise is a cross-border intercity train operated jointly by Irish Rail and Translink NI. It runs between Dublin Connolly Station and Belfast Grand Central Station (formerly Lanyon Place; the new Grand Central opened 2024).
Journey time: Approximately 2 hours in normal conditions.
Frequency: Around 8–10 trains per day in each direction, departing roughly every 1.5–2 hours. First train from Dublin is around 07:35; last back from Belfast is around 21:00.
Price (2026): Varies by booking time. Standard off-peak single: approximately €25–30 from Dublin, £20–25 from Belfast. Early booking can get advance tickets for less. Prices are in EUR from Dublin and GBP from Belfast.
Book at: irishrail.ie or translink.co.uk. Booking in advance is recommended on weekend routes and in summer.
The experience: The Enterprise is comfortable, has a café car, and runs through attractive border countryside. This is the most relaxed way to travel — you arrive in central Belfast ready to walk out. Belfast Grand Central Station (opened 2024, replacing Lanyon Place) is a major new transport hub in the city.
Option 2: Express bus — cheapest option
Several operators run express coaches between Dublin and Belfast:
GoBus/Translink Goldline: The Translink Goldline service runs hourly between Dublin city centre (Busáras) and Belfast Europa Bus Centre. Journey time: approximately 2–2.5 hours.
Bus Éireann / National Express: Also serves the route from Busáras.
Price: Typically €10–20 return depending on booking time. Among the cheapest intercity options in Ireland.
Bus stops: Departs from Busáras (the main bus station, near Connolly on the Northside). Arrives at Belfast Europa Bus Centre, a short walk from the city centre.
Compared to train: Cheaper but slightly less comfortable, and journey times vary more with traffic on the A1 motorway. Fine for day trips.
Option 3: Organised day tour from Dublin
For a day trip to Belfast where you want the logistics handled, a coach tour from Dublin makes sense — especially one that includes Titanic Belfast admission, which is the main draw.
The day tour to Belfast and Titanic Museum (~€45) departs from the Dublin city centre, includes return transport, and covers the Titanic Belfast museum — a genuinely impressive modern attraction in the docklands. Duration: approximately 10 hours.
For those who want to pair Belfast with the Causeway Coast, the Giant’s Causeway, Dark Hedges, Dunluce and Belfast tour is a longer day (12 hours) but covers two of Northern Ireland’s headline sites in one trip. This is a very full day but highly efficient.
See the Belfast day trip guide for what to do once you arrive.
Booking and timing tips
Book train and bus tickets a few days ahead where possible — prices rise closer to travel, especially on Friday and Sunday afternoon services when commuters and weekend travellers overlap. For a day trip by train or bus, aim to catch one of the first two departures so you have a full day in Belfast before the last return service, which is typically around 21:00 for the train and slightly later for some bus operators. If your schedule is tight, an organised tour removes this planning entirely since the return time is fixed and guaranteed.
Option 4: Driving
The distance from Dublin to Belfast is approximately 165km via the M1/A1 motorway. Drive time is around 1.5–2 hours in light traffic, up to 3 hours during peak hours or bank holidays.
Practical notes:
- The M50 toll (Dublin ring road) applies: €3.10 per journey, paid by midnight the following day at the eflow.ie website or at petrol stations. Easy to miss if you’re not used to Irish motorways.
- The road switches seamlessly from Republic motorway to Northern Ireland A1 road — no border check.
- Fuel prices differ: Northern Ireland tends to be slightly cheaper than the Republic due to UK fuel duties.
- Car hire from Dublin includes cross-border permission from major companies; check the specific rental agreement — some budget operators don’t allow NI crossings.
Parking in Belfast: Fairly affordable compared to Dublin. Car parks are signed throughout the city centre; a day in a city-centre car park costs approximately £8–12.
Driving is most useful if you’re combining Belfast with the Causeway Coast (Giant’s Causeway, Carrick-a-Rede, Dark Hedges) — the north Antrim coast is difficult to cover by public transport in a single day.
What to do in Belfast
Titanic Belfast: The centrepiece of Belfast tourism — a museum telling the story of the Titanic’s construction in Belfast’s shipyards. Genuinely excellent, allow 2–3 hours. Book online to save the queue.
Political murals and peace wall: The murals in the Falls Road (Republican) and Shankill Road (Loyalist) areas are powerful visual documents of the Troubles. Black taxi tours are the standard (and safe) way to visit both areas. The Belfast full-day tour with Titanic experience combines several highlights.
Cathedral Quarter and pubs: The Cathedral Quarter around St Anne’s Cathedral is Belfast’s cultural neighbourhood — Victorian pubs, good restaurants, independent galleries.
Ulster Museum: Free, and excellent for Northern Irish history, archaeology and art.
Queen’s Quarter: Around Queen’s University, the Botanic Gardens and the Ulster Museum. Pleasant for a walk.
For the full details, see Belfast day trip guide and the Belfast destination guide. If you’d rather explore on foot with a guide, the Belfast black taxi tour is the standard, well-regarded way to see the murals with proper context from a local driver.
Belfast vs a Dublin-only trip
If you’re deciding whether Belfast is worth the day at all: Titanic Belfast is genuinely one of the best museums in Ireland or Northern Ireland, and the political history on show at the peace walls is not replicated anywhere in Dublin. Against that, a day to Belfast is a full day away from Dublin sightseeing, so weigh it against other best day trips from Dublin if your visit is short. For a longer Ireland trip, the Dublin 7-day Ireland base itinerary shows how Belfast and the Causeway Coast fit alongside the rest of the country.
Combining Belfast with the Giant’s Causeway
If you have two days rather than one, combining Belfast with a night in Antrim and a morning at the Giant’s Causeway is among the best itineraries available from Dublin. The coastline road from Belfast to the Causeway — through the Glens of Antrim, past Carrick-a-Rede rope bridge and Dunluce Castle — is spectacular.
For those managing it as a single long day trip, the Giant’s Causeway, Dark Hedges, Dunluce and Belfast tour covers the main Causeway Coast highlights and Belfast in 12 hours. It’s a long day but efficient. See the Giant’s Causeway day trip guide for more.
For longer Northern Ireland trips including Derry and the Causeway Coast, see Dublin to Northern Ireland transport and the northern Ireland 3-day itinerary.
