La Pierreuse 1660 Château-d'Oex 1660 Château-d'Oex
Parc naturel régional Gruyère Pays-d'Enhaut - Located in the Prealps, south of Château-d'Œx on the left bank of the Sarine river, La Pierreuse reserve encompasses 34 square kilometers of mid-mountain terrain. It extends from the Gummfluh mountain range to the Pic Chaussy range. La Pierreuse is listed in Federal Inventory of Landscapes and Natural Monuments of National Importance. It is a crown example of typical subalpine terrain: rocky zones; alpine prairies with rich flora; marshes; fir, pine and spruce trees; and deciduous forests.
La Pierreuse Reserve, created in 1945, is now managed by Pro Natura with a commission uniting concerned parties for nature conservation in the canton of Vaud.
