Are you planning to stay a couple of days or longer in Asturias and would like to see more than its main cities (Oviedo, Gijon and Aviles)? Then we really recommend you to rent a car!
You can do this in one of the cities. Also, you can rent a car upon arrival at Asturias airport or at one of the airports further away: Bilbao (300 km), Santiago de Compostela (300 km) or Santander (200 km). The highways from these airports to Asturias are well-maintained and usually quiet. This enables you to enjoy the beautiful view on the mountains as well as the rough coastline.
Renting a car allows you to explore Asturias to the fullest!
