The "P'tit train du Nord" trail winds its way through 200 kilometers and has to be one of the best bicycle trails in Canada. It's built on an old railway line which means the trail is relatively flat, even in the hilly parts. The ride curves around rivers, lakes, mountain bases, and through quaint towns like the Old Village of Tremblant. The ride is expertly integrated into the Laurentian region, so over the course of several nights you can cycle, sample local foods, and bunk down at a welcoming auberge (or inn). Diehard cyclists aim to do the whole 200 kilometers in one day, however I find it's best to take your time and enjoy stops along the way. Cycle and Sports Mont-Tremblant is a great resource for bike rentals and their owner Jo Korb (also president of Club de Vélo des 2 Vallées) will give you insider tips for your ride.
