The bus network in Spain is comprehensive and highly popular. Mostly thanks to European Union funding, Spain's road network has vastly improved over the past twenty years and travelling by bus is fast and enjoyable.

There are extensive long distance routes between cities and the service is regular, reliable, comfortable and mostly faster than taking the train. Prices are also very reasonable and travelling by bus is the most common form of public transport in Spain.

Taking the bus in Spain over short distances is equally impressive with high quality, low prices and timely services meaning that their services are always in demand

For rural areas, the service is likely to be run by the local municipality and tend to be more irregular with perhaps only a few buses per day on certain routes. Often it is the only choice.
