Hiking in the Odeigne Fens

This 9km loop crosses the peat bogs and wetlands typical of the Odeigne plateau. The start of the hike corresponds to a gradual climb, visible on the elevation profile, which leads to the highest points of the route around the third kilometer.
The route alternates between gentle inclines, small descents and successive ascents, before a steady descent towards the end of the loop.

Departure and start of the hike

The starting point is in Odeigne, with an initial section through the forest. The path then gradually gains altitude until reaching the first open areas of the fens.

Points of interest along the route

Nazieufa Fens: A vast, typical wetland area, crossed at the beginning of the route.
Pouhon Fen: A remarkable peatland environment, characterized by its open expanses and specific flora.
The Aisne: The river is followed along a calm and wild section of the route.
Observation tower: Accessible via a short climb, it offers a panoramic view of the entire plateau and the surrounding peat bogs.
