There are literally hundreds of videos on YouTube about the Camino de Santiago, from the very well made to the hastily put together. Each and everyone of them tells their own story. I think YouTube is a great source for information for those reading up on the Camino, as well as blogs and forums. So I would encourage any future pilgrim with a few hours to spare to spend time there.
That being said, I would recommend the below set of videos. Andrew Suzuki has recently walked from St Jean Pied de Port to Finistere and he has put together a very slick set of clips with some great advice. He has described this series as a “users guide to the Camino de Santiago”. I think he has managed to fit everything in, including the blisters 🙂 There are also some great pieces of advice from people he walked with. The series is also an extension to his own documentary “Beyond The Way” and if you are Facebook-inclined, you can find out more about here.
