Saint-Calais-du-Désert: Hiking and Heritage

For planning a trip to Saint-Calais-du-Désert, hiking and heritage can be considered as different areas of focus. The Boucle des Moulins runs through the Mayenne valley and is characterised by its trail surface and river crossing. The GR® de Pays Tour du Mont des Avaloirs offers a different scale: stages over several days are planned for this 100-kilometre long-distance hiking trail. The Grotte de Lourdes, Mont Calvaire de la Grotte and Cordouan add a range of historical themes to explore.

Hiking along the Mayenne

The Boucle des Moulins is a hike in the Mayenne valley; 75 percent of its route is on unpaved paths. The route crosses the Mayenne via an iron footbridge; riders can use a ford instead. The trail surface and type of river crossing therefore provide two specific features to consider when assessing the hike.

The route also follows the former millrace, which once supplied the Moulin Arrondeau grain mill. This connection adds a theme of milling history to the landscape and trail features: the watercourse was part of the former supply system for the grain mill. For travellers interested in technical and local history, the hike thus combines specific trail features with a historical theme.

Stages and route characteristics

The GR® de Pays Tour du Mont des Avaloirs is 100 kilometres long; stages of three, four or five days are planned for it. These details provide a clear framework for planning this multi-day long-distance trail. By contrast, the Boucle des Moulins is defined by its surface, river crossing and millrace. The two routes therefore differ in their planning focus: for the GR, distance and stage duration; for the Boucle, specific features of the route through the valley.

Grotto, Calvary and possible early history

The Mayenne also features in connection with the Grotte de Lourdes: it lies at the foot of a slope on the riverbank. For the Boucle, the Mayenne is a river to cross; for the grotto, it is a point of reference for its location. The river therefore appears in two different contexts—as a crossing on a hike and as a point of reference for the grotto’s location.

The Grotte de Lourdes was built in 1902; the Mont Calvaire de la Grotte was designed at the same time. The Mont Calvaire has fourteen stations. At its summit stands a cement cross facing the valley. The number of stations and the cross’s orientation give the Calvary specific spatial features; for the grotto, its year of construction and riverside location are defining characteristics.

Cordouan is described as a possible older site surrounded by ditches; its structures may date from the Iron Age. Unlike the grotto, whose construction is dated to 1902, Cordouan’s archaeological classification is explicitly tentative. A specific construction date and a cautious historical interpretation therefore appear side by side.
