Spain has a land area that is around twice the size of the UK or of the state of Oregon and a population of around 46 million people. Spain has no less than 17 different areas with the Catalunyan and Basque regions in the north of the country being the most keenly nationalistic.
From the cooler cities of the north like Bilbao and Santander to the hot south of Seville and Granada, the country has a great deal to offer if you rent a car in Spain.
Driving in Spain is generally safe and relaxed and in many cities, there are clearly separated lanes for cyclists to use.
