In Lassy, the landscape, walking trails and local history can be explored as distinct highlights. The protected Vallée du Canut represents the natural side of the area; specific details about a walking loop help with planning your time. The Église Saint-Martin and the Maison des Énergies offer further points of interest for anyone interested in the history of the town and its buildings.
Nature in the Vallée du Canut
The Vallée du Canut in Lassy is a natural area protected by the département. Heathland, forests and meadows alternate to shape the landscape. The valley is home to 54 butterfly species and 13 protected mammal species, including eight species of bat. These figures give the destination’s natural attractions a concrete dimension without reducing the landscape to a single habitat.
A marked, 2.7-kilometre trail passes through scenic areas of the Vallée du Canut. The Circuit des Landes also runs through the valley, crossing heathland. These details both put the landscape at the centre, but describe different trails and should not be combined into a single route.
Walking trails and their highlights
The Circuit des Ruisseaux is a moderately difficult walking loop that starts in Lassy. It is 10 kilometres long and takes about two hours and 30 minutes. Its length, difficulty level and approximate duration make it possible to fit this circular route into your available time. The duration is explicitly approximate; the moderate difficulty rating also applies specifically to this route.
The similarly named Chemin des Ruisseaux passes along sunken lanes and by the Croix de l’Ollivrais. Here, the trail’s character and the named wayside cross shape the description. The Circuit des Ruisseaux, by contrast, is described as a loop with a specified length, difficulty level and approximate duration. Keeping the names distinct helps you take the different features of these trails into account when planning, rather than assuming they are the same walk.
The Circuit des Landes adds another landscape feature: it runs through the Vallée du Canut across heathland. Hikers can therefore find both specific details about a moderately difficult loop and descriptions of particular landscape features. For the marked trail through scenic areas of the valley, the stated distance of 2.7 kilometres is the key point of reference.
Church, mill and energy history
The Église Saint-Martin was a priory church dependent on the Abbaye Notre-Dame de Paimpont. As a former priory, it dates from the 16th and 17th centuries and was fully restored in 1999. Its ecclesiastical affiliation, historical dating and restoration are distinct aspects of the same local history: the affiliation points to a former institutional connection, while the dates and year of restoration provide further chronological reference points.
The Moulin du Ritoir ceased operating after the First World War. The renovated former mill building houses the Maison des Énergies, which comprises two exhibition rooms. A permanent exhibition there is devoted to the history of energy; temporary educational exhibitions are also held. The specific exhibition titles may change. The site thus connects the history of the former mill with an exhibition theme that extends beyond the building itself.
The area around the Moulin du Ritoir also has its own connection to local history: a stone bridge beside the mill crosses the Canut and connects Lassy with Baulon. Events and guided tours for groups are offered at the former millers’ house at the Moulin du Ritoir. Together, the church, mill, bridge and exhibitions highlight different aspects, from the former ecclesiastical function and the history of milling to energy history.
For planning purposes, Lassy can therefore be organised around your preferred focus: the Vallée du Canut foregrounds the landscape and wildlife, while the trails each offer different features or timings. The Église Saint-Martin provides a window onto the ecclesiastical past, while the Maison des Énergies explores the history of energy and hosts changing educational exhibitions.
