Snowshoeing at Sommet Morin-Heights Heights.
Sommet Morin Heights boasts a lift ski area, the Aerobic Corridor - a linear year round trail, alpine touring and snowshoe trails.
(The alpine touring is rather limited)
This was our first time at this hill and would recommend it. Close to Montreal, hour-ish drive, nice trails through the woods. Fee access.
Morin Heights (the town and no just the ski area) has a lot of outdoor trails which you can find out more about here: https://www.morinheights.com/Cross-country-Snowshoe-Trails
