I will start my first Camino on December 12, 2014. I am taking a train from Paris CDG airport to Bayonne, which I can book online through "raileurope". However, I couldn't find the train booking information from Bayonne to SJPP. Could someone help? Do I need to buy this part of the train ride advance or I can just get it at the ticket window at Bayonne? BTW, I am from the US.
