The Vallée de Misère

A sensitive natural area

Nestled in the heart of the Alpes Mancelles mountains, this steep-sided valley is overhung on either side by rocky bars and scree dating from the Quaternary Armorican sandstone period, making it a highly picturesque site of remarkable geological and landscape interest, unique in the Pays de la Loire region. Newly acquired by the Sarthe department in 2017, this scree is made up of moorland, dry grassland and woodland, home to abundant and diverse pioneer vegetation (mosses and lichens), with several species that are rare in the region.

A Sensitive Natural Area

to discover

Nestled in the heart of the Alpes Mancelles, this deeply incised valley, overhung on either side by rocky bars and scree from the Quaternary Armorican sandstone, forms a very picturesque site of remarkable interest, not only geologically but also landscape-wise, unique in Pays de la Loire.

This valley is one of the few Sensitive Natural Area (Espaces Naturels Sensibles in french) in Sarthe. Acquired in 2017 by the Sarthe department, this scree is made up of moorland, dry grassland and woodland, home to abundant and diverse pioneer vegetation (mosses and lichens), with several species that are rare in the region.

A place to

walk with the family


On the heights of Mont Narbonne, you can also discover several rare and familiar animal species: llamas, sika deer, fallow deer, mouflons, Ouessant sheep, goats, ponies or Cotentin donkeys frolicking in a wildlife park accessible all year round.

This is an ideal place for a family outing, and also for contemplating the village of Saint-Léonard-des-Bois, surrounded by a rocky cirque where the river Sarthe meanders below.

Take a stroll near the

Vallée de Misère

A perfect place for hiking, you’ll cross this site by taking the “Vallée de Misère” hiking trail, or by following the “Histoires géologiques” trail, set up by the Normandie Maine Regional Nature Park, which takes you back in time.

Also, thanks to the interpretation panels along the way, you’ll be able to understand how the atypical Sarthe landscape of scree was formed, and discover the origin of the name of this Sensitive Natural Area located on one of the slopes of Mont Narbonne.
