This is a link to my website where you can download a free guide to the Camino Francés from Saint-Jean-Pied-de-Port to Santiago and onwards to Finisterre.
The information in the guide was fully updated in summer 2018 and again partially updated in autumn 2019.
The same information is also available in Kindle and printed book format from Amazon. These guides also have detailed route and urban maps for the entire Camino (including Finisterre and Muxia).

It's also available as an app for iOS, Android and Windows Phone.
It's also available on various other platforms such as Apple Books, Kobo, etc. Just search for Walking Guide to the Camino de Santiago. The images attached to this resource are from the printed version available from Amazon. The maps are the same in all paid versions (ie. Kindle, Kobo, apps, etc.)
