I've uploaded a few pics to
http://www.cheddleton.eclipse.co.uk/spain0909/.
The first few are scenes in Rioja.
Pics 7291 to 7333 are in the southern mountains of Rioja, and 7350 onwards are near Nava, Asturia.
The road to the top of the mountain in Rioja was tarmac, with plenty of hairpin bends, as seen in 7311 and 7326. At the top, the road changed to a dirt track, and was even marked on my TomTom and Garmin gps.
The road in Asturia was mostly concrete, very steep in places, although there was one section (approx 5Km) which was muddy and rutted, and I did think about reversing out, but persevered with some spotting. Unfortuantly, I don't have any photos of the bad sections, since I was more concerned about getting past them than taking photos.
