Tip 2: On the Enterprise, find a seat on the left hand side going south to Dublin, right hand side going north to Belfast, for the sea views north of Dublin. Belfast Central was named after the Belfast Central Railway, not because of its location!

For the "Enterprise" train journey from Dublin Connolly to Belfast Lanyon Place, the right-hand side (when facing the direction of travel toward Belfast) is generally considered the best choice for scenery. As you head north, this side provides the most frequent and dramatic views of the Irish coastline, particularly as the train crosses the Broadmeadow Estuary near Malahide and later moves through the coastal stretches of County Louth. One of the highlights of the journey is crossing the Boyne Viaduct in Drogheda, where sitting on the right offers an expansive view of the River Boyne and the historic town. Further north, as you approach the border and enter the Mourne Mountains region, the right side often catches glimpses of Carlingford Lough in the distance. While the left side offers views of rolling green hills and rural farmland, it doesn't quite match the maritime beauty and engineering vistas found on the east-facing side of the carriage. In 2026, the Enterprise service remains a popular cross-border link, and since many seats are reservable, opting for a right-side window seat can significantly enhance the visual experience of this roughly two-hour trip.
