I spent a week in Spain in March, it was meant to be 3 weeks, but I still have a problem with my knee so can't do extended walks on the Camino at the moment, still it was a very worthwhile trip I stayed for a few days in Cuenca for the first time, which is a must visit again for me, then a couple of days in Vigo which I realised is the place for me if I ever move to Spain, I never had that certainty before.
Normally I have 2 or 3 big trips to Spain a year planned but because I am trying to to change jobs I have left it open, but if I sort my knee(s) out then next year I will walk the Camino Frances in January and February which is the months I most wanted to walk it in for a while.
I might try and get a handful of extended weekend visits to Spain by the end of the year but I don't care where just if cheap plane offers come up, but I would love to get to Llanes in Asturias for an extended weekend in July or August
