Language in Galicia? Hola!  I’m travelling the Camino de Santiago from Oporto (PT) to Santiago and Fisterra.  

My family is from Goa and I have a basic understanding of Portuguese (enough for travelling) but virtually no Spanish.  When I travel through rural parts of Galicia or meet people who aren’t as fluent in English, would it be most helpful for me to learn some phrases in Castellano, or would Portuguese be similar enough to Galego?  Do people there have a particular sensitivity to certain languages I should be aware of?  

Muchas Gracias!
