We are starting to explore the Sentier National in the Laurentians and Lanaudière regions of Quebec, just north Montreal.
This section of the trail starts at Route du Lac-Clair and ends at Refuge Swaggin. It's a 16 km out and back (or 8 km one way). It was a perfect summer day hike. Any hike with a swim in a refreshing river is the best kind of summer hike.
