Doing the
Camino Frances solo is an amazing experience. Experience that you will treasure and cherish the rest of your life. Note however, first and foremost, Santiago de Compostela and Saint James, are not moving or going anywhere. They will be there for your 2nd, 3rd, nth camino. Enjoy your camino, meet people from all over the world (Christian, non-Christian, et. al.), and Spain offers more than the Caminos. Where ever you are, if there is a place where you can get water, get water; or food; if there's a place to rest, rest; if there is a bathroom, use the bathroom (Repsol gas stations have bathrooms akin to other countries and they welcome pilgrims). When you see another pilgrim, look up to him/her, and share with them, "Buen Camino!"
I will share my experiences with Spaniards (farm workers, camino workers, etc). I stopped walking and say, "Ola, and que tal?" (Hello, how are things? or buenos dias, que tal?(Good morning and what's up?), and to camino workers (those who clears and clean The Way), I tell them, "Muchas gracias por limpiar nuestro camino!" (Thank you for cleaning our camino). Certainly, they are very happy a pilgrim is speaking to them in Spanish. Then they started speaking at 100 kph and I did not understand a single word. I just smiled and nodded, said "Si, si, bien, muy bien" (Yes, yes, good, very good) then as I was walking away, I said, "buen dia, gracias" (have a good day, thank you). She/he was happy. I was happy.
Oh yes, Spaniards use Google translate "conversation" mode. She/he speaks, you speak; English-Spanish!
Buen Camino
