Hello! I am traveling to Barcelona on March 27th and staying until April 8th. I am interested in seeing the south of France as a day trip. Does anyone have any suggestions as to which place would be the most beautiful to see? I would like to keep the travel time at a minimum and doable by train. It would be nice if it had a beautiful beach, but I would also be interested in a place that had a great winery. Any suggestions would be much appreciated!!!
