"Lac de Gérardmer" is a lake surrounded by mountains and forests. It is supplied by the Vologne, which has its source nearby, at the foot of the Hohneck. The vast forest of spruces and oaks tells many legends. A large, flat stone is particularly famous. Emperor Charlemagne would have come to these woods to hunt game and wolves. Feeling tired, he would have rested on this stone, which took his name. A little further on, Saint Colomban would have escaped the pagans who were chasing him. A large stone opened in two and closed, allowing him to escape from his persecutors.
