Yes, buses do run on Sundays in Galway, Ireland, but travelers should be aware that the frequency of service is typically reduced compared to the Monday-through-Saturday schedule. The main city service, operated primarily by Bus Éireann, runs most of its major routes (such as the 401 to Salthill or the 402 to Merlin Park) on Sundays, though they often start later in the morning—frequently around 9:00 AM or 10:00 AM—and may end earlier in the evening. In addition to the city routes, the TFI Local Link Galway services provide vital connections to rural areas and surrounding towns, though some specific local routes may not operate on Sundays or public holidays. For those traveling between Galway and other major cities like Dublin, Limerick, or Cork, private operators like Citylink and GoBus maintain a very robust Sunday schedule, often running hourly or near-hourly services throughout the day. In 2026, it is highly recommended to check the "Real Time Ireland" app or the official Bus Éireann website before traveling, as timetable updates are common and specific routes may have seasonal variations. Overall, while you can certainly navigate Galway by bus on a Sunday, you should plan for longer wait times between departures and double-check the final bus times for your specific route.
