I biked Le P'tit Train du Nord perhaps 15 years ago. I parked in the big free parking area at the southern terminus and had reserved a shuttle to take me and my bike to the northern terminus, Mont Laurier. I don't recall the name of the shuttle service. It was all very easy to arrange and inexpensive. I rode the trail in early September and the trail wasn't busy at that time, but the weather was excellent. The northern part of the trail in particular goes through a very pretty, sparsely populated area with lots of forest & lakes. I took a little off-trail excursion on my bike when I got to Mont Tremblant. The trail wasn't paved at all at the time I rode it, but the surface was good. I believe that much of the trail is paved now. It's a great trail.
