At the entrance of the Val d'Illiez above Monthey, Troistorrents combines a Chablais village with the resort of Morgins in the Portes du Soleil.
The village, on the hillside above the plain, lines up houses, chalets and residential districts, while Morgins, a border resort of the Portes du Soleil ski area, adds a segment of holiday homes. The setting between the Dents-du-Midi and the valley defines the appeal.
The closeness of Monthey and the plain draws families, while Morgins targets a second-home clientele. Chalets with a view and villas lead a market at measured prices.
