The perfect family hike! Head to the mountain pastures near Lake Roy, the jewel of Praz de Lys Sommand, facing Mont Blanc.
The magnificent Roy Glacial Lake, a true gem of our resort. Panoramic views of the Grandes Alpes.
The walk to the lake along this balcony-like trail facing Mont Blanc is breathtaking.
Marmots are sure to be out on the mountain pasture—be sure to set aside time to watch them!
During summer vacation, the site can get very crowded: it’s best to go before noon or in the late afternoon, and be sure to use the Giffre shuttle buses to get to the starting point.
Choose gear that's appropriate for your skill level and the weather. Stay on the marked trails.
Tips
A must-see spot for spotting marmots! From mid-July to mid-August, take advantage of the Haut Fleury chairlift’s opening to reach Lac de Roy at 1,660 meters via the downhill run.
