Boucle de l'Agrion de Mercure

Discover the flora and fauna of the Bresle on this 7 km loop, which takes in the rich, unspoilt nature of the aquatic environment.
You'll be able to admire numerous natural habitats such as meadows, alluvial forests, pond edges and dry grasslands where wild orchids grow!
You'll also come across local wildlife, including the mercury agrion, the dragonfly that gives the trail its name! This insect, recognizable by its beautiful blue color mottled with black, inhabits the banks of the Bresle, and is unfortunately threatened by the disappearance of its natural habitat.
The trail will tell you more about this insect, as well as the other animals that inhabit the Bresle valley, such as amphibians, migratory birds and Camargue horses.
