Cudillero to Mérida Road Trip: Asturias to Extremadura

The road from Cudillero (Asturias) to Mérida (Extremadura) spans 700 km along the A-66 and A-8 highways. This route transitions from the lush, rainy Atlantic coast to the arid, sun-baked plains of Extremadura. Historically, the Via de la Plata, a Roman road from Seville to Astorga, roughly parallels this drive.

The drive takes about 8 hours nonstop, but you'll want to stretch it over two days. Key waypoints include León, Salamanca, and the Sierra de Guadarrama.
