The great marsh of Liesse-Notre-Dame is in the heart of the Marais de la Souche (Liesse-Notre-Dame, Pierrepont, Chivres-en-Laonnois…).
It is made up of various natural environments: peat bogs, woodlands where numerous heritage plant and animal species thrive.
The trail allows you to discover these areas in complete tranquillity… and in all seasons! (in winter, boots are strongly recommended)
