What visitors say
This loop strings together three trails, La Roche, La Coulée and La Corniche, on the mountainside above Lac Monroe in the Diable sector of Parc national du Mont-Tremblant. The payoff is two rocky lookouts over the lake and surrounding Laurentian hills, and hikers also mention small falls and water features on the way up. Nearly every review is five stars.
The full loop is about 8 to 8.5 km with roughly 370 m of climbing and takes most people three to three and a half hours. La Roche and La Corniche are wide, well-kept paths, rocky lower down and softer dirt higher up, while La Coulée is narrower and rougher. Several hikers found the climb to La Roche steep and steady, while others rated the whole loop easy to moderate. There are benches at the top and plenty of room to spread out for lunch.
It suits families and hikers of most fitness levels, and dogs are allowed on these trails. After the hike, visitors swam at the beach they had seen from the top, and kayak rentals are nearby, though one reviewer noted they close in the afternoon. Wildlife sightings include squirrels and deer. The route also works on snowshoes in winter, though one group found the 2.4 km climb to La Roche took much longer on snow.
The main caution is crowds: a fall Saturday was very busy. One hiker found the forest stretches unremarkable, just a way to reach the views. Non-hikers should bring poles, and bug spray helps in early summer. As this is a Sépaq park, entry fees apply.
