A commented walk to discover this ancient island of the Rhone, called «Prentegarde» formerly, and now «Printegarde» by the grace of its classification as a Natura 2000 site (2005): we see and hear many birds, we admire and appreciate the sweetness and harmony of its landscape of water, reeds, forests, animated by the flight of many dragonflies, ducks or egrets; and that’s not all: we will add that, perhaps, during the walk, you could spot traces of the beaver guided by specialists who will tell you about this discreet but endearing animal. It is also an opportunity to discover the operation of the developments carried out by the CNR as part of the construction of the Baix-Logis-Neuf dam, for the hydroelectric production and the life of the residents installed there for a long time, on these lands rich in alluvium of the Rhone but living in fear of the occurrence of the next flood that will submerge land, crops and dwellings.
