Yes, it is the week-end of 8-9 February. You can also go to Bas St-Laurent and Gaspésie for that week-end. The trails are always nice and empty there. Even Chaudière-Appalaches can be a great choice. The trails are awesome right now. This is no more farther than St-Zenon, if not closer.
North of Montreal (Laurentides - Launaudière) is always overcrowded in my book. I just don't get why the tourists always go there. Quebec is a lot more than those 2 areas. Click here to learn more about the Open House event. http://sentiersmotoneigegratuitsfcmq.com/en
