We did the normal route (route de Napoleon, also called Camino Frances) starting in St Jon Pied de Port in France ~ hiking over the Pyrenees and then across Spain. The most expensive part was the airfare, as we stayed in hostels asking the way specifically set up for the Camino de Santiago. It ranged from 4 Euro to maybe 15 Euro a night, most being around 8 Euro including breakfast (which in Spain was mostly coffee and bread with marmalade or jam). We took 2 months, but it can be done usually in 35 days or so. Was an incredible and safe experience that not many Americans know about but for 2 middle aged women we never felt unsafe, and it was amazing.
