To experience and explore the garden differently in winter Available in French only Élio, a charming little squirrel who is a bit absent-minded, accidentally discovered an extremely rare botanical treasure: a bright red hazelnut! However, in a moment of distraction, he hid it for the winter and forgot his location, as often happens to him… Can you help Élio and his friends find this precious hazelnut? Come and experience an outdoor and independent activity that takes the form of a fun trail in the Garden using a mobile application. The mobile application is designed to act as a virtual facilitator and allows participants to directly validate the answers to the tests on their smartphone, to be geolocated, to obtain clues and directions. The games are directed by the application, but the tests themselves are physical and dynamic. This activity is a Parcours ludiques design.   Where to download the app? In the lobby of the Botanical Gardens reception complex.
