We have 3-4 days planned in Barcelona this summer. My husband is quite set on making a trip across the border to France for the day! I think it's ambitious, but am willing to keep an open mind, especially if you wise travelers have some suggestions for accessible towns or experiences.
I have seen some tour groups offering bus trips to the Andorra region, but we are more of a train ride/walk-explore type travelers. Is a high-speed train to Toulouse or Marseille really reasonable for one day? What about more local-quant villages? Any thoughts appreciated. Thanks in advance!
