I went for hiking in the Dolomites (Italian Front) the last days. (Terrible weather, nothing but snow all over the trenches on Mount Piano) Nevertheless it was very impressive to see the Lagazuoi (Minewar near Cortina d�Ampezzo) and the many Austrian fortifications in South Tyrol.
I have also visited the Battlefields of Verdun in Lorraine and the Lingekopf in the Vosges several years ago. For this summer I plan to visit Chemin de Dames (especially Craonne) and maybe the Somme area. Does anyone have suggestions for detailed maps of the old frontlines for hiking or maybe has experiences by visiting WW1 battlefields in Northwestern France/Belgium himself?
Always thought it would be advantageous to have the old ww1 frontlines as an app in somewhat like google maps.
For myself I can recommend the Lingekopf in the Vosges:

and Verdun where my grand-granddad fought:

Did some of you ever visited the Battlefields of the Great war?
