Starting out from Lugny, you'll 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 screechstone testifying to an ancient "lavière", a forest of oaks emerging from the boxwood. You'll be guided by a praying mantis. There are four biotope panels along the way and around 50 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.
