Hidden away from the most frequented paths, an little-known walk plunges you into the Chéran valley, a true natural gem. Over a 14 km loop with 300 meters of elevation gain, the walker discovers forgotten castles, old hamlets, and a mill bearing witness to the past, all within a preserved setting where the river sets the rhythm for every step.
A gentle immersion along the Chéran
From Alby-sur-Chéran, a medieval village located at 450 meters altitude, the route runs along the right bank of the Chéran, on a rehabilitated path that extends the one from the Cusy footbridge. Classified as a “wild river,” this lively water provides an ideal backdrop for this walk where nature and history intertwine.
Sometimes calm and reflective, sometimes lively and playful in the rapids, the river accompanies hikers in a changing atmosphere that makes each bend new. Brown trout and dragonflies color the environment with life and movement.
A forgotten fortress: the Château de Pierrecharve
Just over 3 kilometers away, perched on a rocky promontory, the Château de Pierrecharve emerges from the foliage. This 13th-century relic, although private and closed to the public, impresses with its stature. It overlooks the valley and recalls its strategic importance at the time when Alby controlled the passages to Annecy.
“Seeing it emerge between the trees is like an open window onto the Middle Ages,” says Marie Dumont, a local history enthusiast.
Open panoramas from the heights
The path gradually gains height until the Crêts, at about 600 meters. There, the atmosphere changes: the forests open up, giving way to bright meadows. At Grand Creux, a natural clearing reveals a striking view of the Bauges massif, perfect for a well-deserved break.
Between rustic hamlets and rural heritage
The descent leads walkers back to the Granges and Balmettes, two small hamlets that bear witness to rural life of yesteryear. Stone buildings and slate roofs tell a story of a time when agricultural activities dictated daily life. One can still feel the memory of cheese and haymaking of the past.
The Moulin Janin: a testament to human ingenuity
Following the course of the Chéran, you reach the Moulin Janin, an old 18th-century water mill restored for visits. It reveals the techniques of the past for harnessing the power of the current. Educational panels, nearby observable fauna, and a peaceful atmosphere make it an iconic stop.
“This mill was the heart of the valley. It preserves the memory of a disappeared world but still tangible here.”
– Jean Moulin, descendant of millers
Return via Le Châtelet and Saint-Maurice Chapel
The loop ends by passing through the hamlet of Le Châtelet. Here, the landscapes change again: hedges, clearings, and pastures follow one another until you come across the discreet Saint-Maurice chapel, built in the 17th century. Its bell tower signals the near return to Alby.
A teeming biodiversity in every season
Throughout the trail, nature lovers will be delighted: wild orchids in spring, insect ballets in summer, forest birds and elusive roe deer at the edge of the woods. The kingfisher, for its part, remains the winged ambassador of this still preserved valley.
