Very useful. I did a short hike from Sarria to Santiago last year (2015) and plan the whole thing this year (2016). This really shows me what's coming and I know what I can do. It will be a wake up call based on the profiles.
On May 2016, God's help, I'll be on my first Camino (Frances) and these maps offer important indications for preparing the way plus they summarize much information within only two pages and are so easy to consult. Thank you so much!
