Nancie and I will be heading out to Mont-Tremblant soon and I'm in the beginning stages of planning some of the hikes I'll be doing there. So far I've identified "Le Carcan" as the most likely trail. It sports 14,4 km of trail with an estimated time of completion of 5h-6h. Most notably it leads you on a climb of the second highest peak available in the park (883m) while visiting several waterfalls along the way. I just hope I'm in good enough shape.
