This interactive map is a companion to Bryson Guptill's book Camino Francés: A Practical Guide to Walking the Pilgrim's Path from France to Spain.
The book describes the 800 km route from St. Jean Pied de Port to Santiago with suggestions for daily distances and places to stay. It includes detailed descriptions of the route with colour maps to keep you from getting lost and describes our daily journey, where we stayed and what we ate. It's an invaluable companion for your pilgrimage along the Way of St. James.
Bryson's route along the Camino is highlighted in red; each overnight stop is marked with a green marker with the number day of the walk inside. Click or tap on the marker to see the name of the town or village, the overnight lodging Bryson used, and the distance traveled that day, and in total to that point.
If you're actually walking the Camino and using this map as you go, you can tap on the "locate me" icon in the top-left corner of the map, give you device permission to provide its location, and the map will zoom right to your current location.
This blog post by Peter Rukavina details the technical process that went into creating this map.
