I took the train back- odd as that might seem- which wasn't cheap, and took nearly 24 hours! But it suited me, as it gave me a long chance to unwind, and in a sense, say 'goodbye' to the walking pilgrim lifestyle I had lived for nearly three months.The daytime train through Spain retraced some similar landscapes, though not the exact route, that I had walked through. Then I had a couple of hours wait at Hendaye before I boarded the night train to Paris.
Some young ones I met found the cheapest option. They went overland to Porto, then caught a flight out from there that was far cheaper than any of the options they found from Santiago.
