Admire the highest point in the Vosges massif on a walk between the Haag farmhouse inn, the Diables Bleus monument and the famous Grand Ballon, towering 1424m above Alsace.
A must if you're travelling along the Route des Crêtes.
Highlight: Not to mention the view, the orientation table and the radome.
