Hi Richard - we were in the Asturias / Picos a couple of years ago. The
mountains were wonderful and we drove for miles and miles through them
without meeting any traffic - BUT it takes forever to get anywhere and the
coast roads are very busy! We drove from Llanes to Fuente De and what we had
expected to take 2 hours took 4! Then when we finally arrived, the top of
the mountain was shrouded in mist - this is not unusual as we later found
out. Having driven all that way we queued anyway - 90 min wait - and arrived
at the top in a thick wet mist. Some people just turned around and joined
the down queue!
Now you know why this is a lovely 'green' part of Spain - it rains! of
course as we're English this didn't bother us too much!
We had a lovely holiday and certainly found this area very different to
other parts of Spain - have a great trip
