Val d'Illiez / Val de Morgins

From Monthey a road runs southwest into the Val d'Illiez, first climbing up the steep hillside in sharp bends and then continuing up the slopes of the valley high above the left bank of the Vièze. Amid the woods of chestnut-trees are many large boulders brought here by glacial action, including the Pierre à Dzo, resting on a base no bigger than a man's hand, and the Pierre des Marmettes, with a small house on the top.

In 6km/4mi the road comes to Troistorrents (760 m/2,494ft), a prettily situated village at the mouth of the Val de Morgins, through which a road runs up to Morgins. The road continues beyond Troistorrents ascending the beautiful valley (many waterfalls) alongside the cog-railroad, with views of the Dents du Midi and
