My boyfriend and I will be traveling to Barcelona in late July, for 8 days. This is my first time traveling to Europe and I figured, because train tickets are so cheap, we might as well take a day trip. I was thinking South France, possibly Narbonne or Perpignan. I don't think I would want a trip longer than 4 hours. My question is, should I forgo my desire for France and go somewhere in Spain i.e. Madrid, Valencia, or does anyone have good suggestions for South France? Day trip suggestions in general?
Many Thanks! :)
