For the adventurous and the curious. The treasure hunt is designed to immerse you in the world of smuggling, thwart the dangers and discover a treasure. Welcome to Joséphine’s world. A long time ago, this little girl lived in Villers le Lac, where her father, Pierre, was a famous smuggler who had decided to stop, but had nevertheless embarked on his adventure one last time. Unfortunately, he was caught by the customs officers and sent to the galleys. But before he left, he left his daughter some clues to help her find his treasure. There are 10 signs along the walking route with clues and a survey. The answers are revealed on the next panel. It’s a great way for the whole family to discover the Saut du Doubs in a different way, while having fun and learning lots of new things!
