This looks like a fantastic trip! I was just going to take the AVE from Barcelona to Madrid for a few days but maybe I'll take the long way back home through Cuenca and Morella!
Love the photos. Slovenia and Croatia just got bumped up on my to-visit list :P
Wow, you managed to do a lot in three days!
Interesting to see an Iceland trip without renting a car. I don't drive but I'd love to visit some day too!
Your photos are amazing!!
