This route was once an old railway turned into a paved trail between Kila, Montana and the lake town of Somers, Montana. It is 22 miles long and follows the old Great Northern Railway. There is trial parking at both ends and a couple of bathrooms accessible on the route.  

The route starts at Sentier du Massif trailhead in Notre-Dame-de-la-Merci and ends at the end of sentier des Contreforts trailhead on Chemin du Lac Clair in Saint-Côme.
