The exact route we walked in 2018 is shown by the blue line on the Institut Géographique National (IGN) map below. Note, it can be slow to load, especially the line showing the actual route. It was created on the Géoportail website and it may be enlarged by clicking the + sign in the top left-hand corner.
Zooming in to a scale of 500 m (seven clicks) produces the TOP 100 map, and one more click (also with a scale of 500 m) shows the TOP 25 map, which is the view we use when making our homemade maps. The making of these maps is described here. To see this map in full screen, click the icon in the bottom right-hand corner.
