Spain’s bus services are provided by many different bus companies whose routes comprise an extensive network. The biggest of these Spanish bus companies is ALSA, which operates an extensive network of bus routes throughout the country including international routes to Andorra, France and Portugal. Because of the excellent bus services, the bus should be the first choice for travellers not travelling with a railpass.
Eurolines have international services to most major cities in Spain and travellers using the Eurolines Pass can travel to Alicante, Barcelona and Madrid. Eurolines Pass holders can also use the pass to make domestic journeys on the Barcelona–Madrid route, an exception to the international travel only rule of this pass.
Busabout buses serve the following Spanish destinations: Barcelona, Madrid, Pamplona, San Sebastian and Valencia.
