The idea of this long hiking trail is to follow approximately the dividing line of the waters between the Mediterranean and the Atlantic. It starts at the Ballon d'Alsace and ends in Andorre-la-Vieille (Andorra).
It is not a treasure hunt, but a free track game, open to everyone, ideal to practice with family or friends.
Do you know? This involves looking for small boxes hidden in nature: discovery of the territory guaranteed!
