We are spending a week traveling independently in Barcelona, and then need to get up to Bayonne to join Rick Steves' Basque Country tour. We will depart from Barcelona on Sun, 6/21/14, and need to be in Bayonne Sunday, 6/22/14 at 5 pm to join the RS tour.
No flights direct. Train takes 8-10 hrs, so we are looking at a Vueling flight from Barcelona to San Sebastian (1 hr, 10 min; 80 euro), and then taking a bus to either Biarritz (spending the night and sightseeing, then a bus to Bayonne the next morning) or Bayonne from San Sebastian. Is there a better strategy to get from Barcelona to Bayonne? I've read about taking a ferry across Txingdui Bay to Hendaye, and then a bus to Biarritz from Hendeye, but am uncertain how to proceed.
