The CALIBUS network, operated by Transdev Urbain Libournais, serves the Communauté d’Agglomération du Libournais free of charge. It comprises 4 urban lines, 6 regular suburban lines, 3 downtown shuttles and a “Plage” shuttle serving the Dagueys beach on Sundays during the summer. It is complemented by a transport-on-demand service and a transport service for people with reduced mobility.
