Fly to/ from – Where can I fly in / out of to begin the trip?

The easiest entry points are Barcelona and Bilbao. Both have frequent flights to and from other European cities. Barcelona also has some direct flights to/from the USA. Madrid is only 1 hours express train away from Zaragoza, where many of our journeys begin. Biarritz, Pau, Tarbes and Toulouse are other possibilities with some, but limited connectivity.
