Treasure Hunt 'The Adventures of Rose and Louis at Hahnenbrunnen'

The starting point of this treasure hunt, titled "On the Trail of the Blueberries," is at the Col du Hahnenbrunnen.

Rose and Louis are visiting their grandmother Anna, a cook at the Hahnenbrunnen farm-inn, who is short of blueberries to make her famous pie.

Families, equipped with a game booklet and a map, set off to find clues to discover who to ask for these blueberries.

Over nine stages, taking about 1 hour and 15 minutes, young and old follow the adventures of Rose and Louis while exploring the mountain environment.

The 2.8 km route alternates between shaded and sunny areas.

The game booklet and map are available for download, and a paper version can be picked up at the Guebwiller Regional Tourist Office.
