||From the parking lot near the Lac d'Emosson dam. Follow the road across the dam. Follow the path for about 500 m at which point you will follow the signs to Chalet de Loria. The trail will be marked with yellow blazes and continues up and down. The difficult sections are equipped with metal steps, chains, and bars to make the hike easier. After about an hour, Grand Perron will come into view on your right. Follow a distinct path (marked by Cairns) which breaks off from the main path to your right.
