With the resources that are available–books, apps, and so forth, you can plan and do your Norte and/or Primitivo with confidence. I hope to post images of the journey to inspire you to plan that trip of your own that you have been dreaming of.
Meanwhile, check out Susan’s Healing Miles: Gifts of the Caminos Norte and Primitivo.
Guy Joaquin, co-coordinator of the Northern California chapter of American Pilgrims, posted a ZOOM video on his walk on the Camino Primitivo. He gives an introduction about the origin of the route, some packing suggestions, info on mileage and options for starting points and then takes you along on his hike from Oviedo onward. As the route split at the town of Pola de Allenda, Guy walked the lower route, La Pola, and Sue Lopez, chapter member, walked the high route, the Hospitales. Link here.
