A hike in Champagne to discover the vestiges of the First World War and the terrible battle of the Chemin des Dames.
The observatory and the abbey of Vauclair are distant of 10 kilometers (20 kms round trip), the two sites are connected by a forest path. This path is called "chemin du facteur" (letter carrier's path) because it was the path taken by the letter carrier before the war. The path is not very practicable in rainy weather and in summer there are many reports of mosquitoes. Moreover, it is quite difficult to distinguish the traces of the fighting along the path. It is possible to go to both sites by car without doing the hike. Everything is free, there is no entrance fee. The observatory is really worth a look, it allows you to see a large part of the Chemin des Dames in a single glance.
