Parc naturel régional Gruyère Pays-d'Enhaut - The village of Lessoc is in the federal inventory of sites of national importance. It is made up of a dense network of houses and farms from the golden age of Gruyère, with strong presence of late gothic decor (window and door frames) modeled after those of the medieval city of Gruyères. It is one of the rare villages in the l’Intyamon to have a square with a remarkable covered fountain.
The trail leads out of Grandvillard , then over the stream of Les Marais to below the waterfall and to the grotto, which is a place of Gruyère pilgrimage . In the village centre there is a well with its imposing cupola.
