Up until about 2018 I did not really use the bus service when visiting Cork mainly because of the frequency of the service however for the last three years I have made extensive use of the service and have tried nearly all the routes but did encounter issue when using the orbital routes but I will not describe the problems here.

Public bus services within Cork City are provided by the national bus operator Bus Éireann. City routes are numbered 201 through 226 and connect the city centre to the principal suburbs, colleges, shopping centres and places of interest. Two of these bus routes provide orbital services across the Northern and Southern districts of the city respectively. Buses to the outer suburbs and towns, such as Ballincollig, Glanmire, Midleton and Carrigaline are provided from the city's bus terminal at Parnell Place in the city centre. Suburban services also include shuttles to Cork Airport, and a park and ride facility in the south suburbs only.

The first 24-hour bus in Ireland, route 220, was initiated in Cork in January 2019. The 220 links the two major satellite towns of Ballincollig and Carrigaline with the city centre and operates once an hour between the hours of 01:30 - 05:30. One year after 24-hour service commenced, Bus Éireann announced they had witnessed a 70% growth in passenger numbers on the route, resulting in 1.3 million customer journeys. Local politicians have called for the introduction of further 24 hour bus routes in the city owing to the success of the 220.
