The bus journey from Galway to Dublin typically takes between 2 hours and 20 minutes and 3 hours, depending on the service type and traffic. Express services, such as those operated by Citylink (eircom) or GoBus, are the fastest, often reaching Dublin City Centre in about 2 hours and 30 minutes via the M6 motorway. Some of these express buses go directly to Dublin Airport, which takes roughly the same amount of time. Standard "multi-stop" services operated by Bus Éireann can take closer to 3.5 to 4 hours as they stop in various towns along the way. In 2026, buses remain the most popular way to travel this route due to their frequency (often every 30 minutes) and the fact that they are usually faster and cheaper than the train, which requires a transfer or a longer journey time from the outskirts to the city center.
