With family or friends, the treasure hunt is an original activity that takes adventurers through the Grande Cariçaie nature reserve.
In a playful format, participants set off from Estavayer-le-Lac to discover Switzerland’s largest lakeshore marshland, with a special focus on the history of the reserve. Questions, riddles and puzzles enhance the walk in the heart of nature. Explorers must use observation, reasoning and memory to solve the challenges at the eight stations. In short, the treasure hunt is fun for all ages.
