Since routes to Saint-Jean-Pied-de-Port are numerous and depend on where you’re flying to, here are direct links to the main railway and bus operators:
🚂 Renfe – Spanish national railway
🚂 SNCF Connect – French national railway
🚌 Alsa – Spanish intercity buses
Tip: Most pilgrims flying into Madrid, Barcelona or Bilbao use Renfe. Flying into Biarritz or Paris? SNCF is your friend.
