I walked alone in winter from SJPdP to Samtiago in 2006, 2007, 2008, and 2009. Later years I finished autumnal caminos in December .
I never had a reservation and always carried my pack staying usually in Xunta albergues often the sole pilgrim, but also in back rooms of an open bar/restaurant.
In winter hospitaleros usually knew what was open on the next section. There were no summer crowds and beds/bunks were available.
Walking off-season during those past years I rarely saw more than 20 pilgrims at one time. There usually was a strong sense of camaraderie amongst those of us on the route especially during storms or difficult stretches.
Difficult CF stretches after storms could be; the Valcarlos route up to Roncesvalles (as you know the Napoleon route is closed from November to April), across the Montes de Oca from Villafranca, Najera to Santo Domingo de la Calzada, Monte Irago and, of course, to and from O Cebreiro. You must be prepared for
snow in the mountains.
Many who go at this time wear and carry lightweight but warm layers which can easily be added or removed. Here are a
kit list and tips from the viewpoint of a woman who often walked in cold weather
For any winter camino I also stress this bit of info re:
carrying food supplies.
Many of my earlier posts on the forum describe winter walking. If you would like further info please just ask.
Happy planning and
Carpe diem!
