My husband, daughter anI are flying into Barcelona and driving to Llafranc for three nights. We love to swim and hike. Any suggestions? Then we drive to Lleida to drop off our daughter to take a train to Madrid. We head north for fly fishing in Aren. Big question....we have four nights to spend time leaving Aren back to Barcelona. What towns should we not miss? Minimum stay for us is two nights, don't like to drive everyday. We love to swim and hike and drink great wines and eat great food. Thank you for any suggestions!
