Family bike treasure hunt

Family mystery ride along the river - 23 km. After adjusting your bikes and collecting your log books, you're off on a family mystery ride. You'll reach the banks of the Yonne and begin your excursion along the river. This isn't a stage in the Tour de France, it's all flat and easy.
You'll stop regularly to answer the questions in your logbook, to look for a detail on the façade of a monument or house, or a hidden object... You'll pass through the locks one by one and arrive at Champs sur Yonne for a friendly meeting with a charming lady and her 4-legged guests. Then it's back to the other bank of the Yonne and a leisurely drive back to Auxerre to hand in your precious notebook with the answers to the riddles. A gift will be given to the young participants.
