Public bus services within the city are provided by the national bus operator Bus Éireann. City routes are numbered from 201 through to 219 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, 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.
