Mont-L'évêque lies between the sandy heathland of the Ermenonville Forest and the limestone plateau of the Valois Plain. Near Mont-L'évêque, the Nonette marks the transition between the forest massif and the agricultural plain. This brings together landscapes, walks and history when planning a stay: forest and plain offer contrasting scenery, while waterways and buildings tell of past uses.

Forest, plain and water

The Fossé de six pieds rises at a former watercress bed and once supplied an old mill. The Sangle is a small tributary that runs parallel to the Nonette. In 1970, it was diverted to power the large mill at the entrance to the village and, at the same time, feed the pond and canals in the château park. These waterways reveal different aspects of the area's history: their use to operate the mills and to shape the park.

The Château de Mont-L'évêque stands in a large park crossed by the Nonette, which forms a pond there. The park can be visited free of charge every day on a self-guided walk. As access conditions may change, check them before your visit. This makes it possible to combine a visit to the park with a look at the local water landscape.

Exploring on foot

The “Entre plaine et forêt” walking loop is 2 km long and takes about an hour. It starts at Place de l'église in the upper part of Mont-L'évêque. Its name points to the contrast between plain and forest, which also shapes the village's location. For a longer hike, there is the “Mont-l'Évêque – Un village lié à sa forêt” route, which is 7.2 km long. Its stated starting point is the cemetery car park; check the parking arrangements before you set off.

The two routes differ both in length and starting point: the loop is a short walk with an approximate duration, while the hike covers 7.2 km. Another option is Route 393, which offers a forest-bathing walk from Mont-L'évêque. You can choose between a loop, a longer hike and a walk themed around the forest. Route details may change.

Buildings and the history of defence

A Bloc Chauvineau stands at the crossroads with the path leading into the forest. It marks the Chauvineau Line in the village: this 130 km defensive line around Paris was begun in 1939 under the direction of General Chauvineau. The German invasion in May 1940 interrupted the work, and the line remained unfinished. The line's concrete shelters were designed to house cannons; the Nonette valley was also used for defence. The Bloc in Mont-L'évêque is thus part of a larger defensive line, not just a local structure.

The old floodgates are also part of this history. They were installed in Mont-L'évêque to flood the valley in the event of a German invasion. The Église Saint-Germain, dating from the 13th century, offers a much older historical connection. Together, the church, defensive structures and waterways provide insight into different periods and uses of the area.
