Hello folks:
I will fly from the US to Copenhagen in early June and end my Europe trip in Barcelona in the third week of June. It's going to be my second visit in Copenhagen and my SO has a music event to attend in Barcelona. This leaves us with approx. one week (second week of June) with no fixed destination. Where should I go? Theoretically, this place could be anywhere in Europe, but we don't want to fly too much. So, somewhere in Spain with a direct transit link with Barcelona would be great. I have been to Madrid and NW Spain. Yet, from Madrid, I have not made day trips to any charming town nearby except Salamanca. So, this would be a good time to do it, together with Zaragoza (en route to Barcelona).
From Google Flights, Madrid is the cheapest to fly to (Iberia). There are also flights served by low cost airlines to Barcelona and Bilbao.
I saw Carlos' post about the water shortage in Barcelona. However, we already purchased tickets to the music event and paid for our hotels. We promise to be conscious of our water use.
