Pick up your card at the Tourist Office, located next to the station, or at the tourist information point at the entrance to the cathedral. Make your way to the starting point of the "Détective-Trail" at Lausanne Cathedral, where the first riddle is already waiting for you. The itinerary will guide you from one enigma to the next, and you can solve them according to the information on the spot. If you solve the riddles correctly, you'll be able to open the lock on the treasure chest and leave with a little souvenir.
