Leaving from Lugny, you will discover a corner of the Haut Mâconnais region, a piece of its history and a variety of environments: dry limestone grassland or "teppe", old quarries, a scree slope bearing witness to an ancient "lavière", a forest of oaks emerging from the boxwood. Follow the praying mantis as it guides you. There are four biotope panels along the way and around fifty signs to help you identify the trees and shrubs. Equipment: bring good shoes. Guided tours on request. Site managed by the Conservatoire d'espaces naturels de Bourgogne in partnership with the commune of Lugny.
