These trails are rather technical, in a typical Laurentian/Appalachian way; lots of ups and downs, a few solid climbs, plenty of roots, rocks, fallen trees and mud as well a small section on road.
The route starts and ends at the Montagne Verte parking lot on Chemin du Lac-Baptiste, in Labelle.
A few meters after the trailhead, make a left to go up Montagne Verte clockwise. Come back down the other side and, at the crossing, make a left again, following the signs towards Nez-de-l'Indien. When you reach Nez-de-l'Indien summit, go to the left at the intersection to head towards Chemin Thomas-Robert. When you exit the trail, make a left on Chemin Thomas-Robert and keep going until you get to Chemin de Lac-Tremblant-Nord, on which you make a right. When you reach Chemin du Village, make a left and then a left again at Chemin de la Chapelle until you're at the bottom of Mont-Tremblant. Go up the small street alongside the ski lift and proceed to start your climb via Grand Brûlé trail. When you reach the Pic White summit, go past Grand Manitou refuge and follow the instructions for the Sommets trail. Keep going on Sommets until you reach Pic Johannsen, then take the Johannsen trail for a few meters and make a right, following the sign for Toit de Laurentides. From there, it's mostly downhill until you reach the trailhead on Chemin du Lac-Supérieur. Turn around and do it in reverse.
