How Much Does a Return Ticket from Dublin to Belfast Cost?

**No fixed price**—fares vary by mode, operator, booking time, and travel date:

• Train (Enterprise, Irish Rail/NI Railways): €20–€60+ return (book ahead for best)
• Bus (Bus Éireann, Translink, Aircoach, private): €15–€40 return
• Flight: Not practical (DUB–BFS 30 min flight + 2+ hrs airport); rare, expensive
• Car: ~160 km, 2 hrs; fuel + tolls (M1/M50) ~€25–35

Best sources for live fares:

• Irish Rail / Translink (train)
• Bus Éireann, Aircoach (bus)
• Omio, Trainline, Rome2Rio (aggregators)

Book 2+ weeks ahead for cheapest. Off-peak (midday, midweek) saves 30–50%.
