The forest of Pfyn-Finges nature reserve is the centrepiece of the regional nature park Pfyn-Finges. The forest of Pfyn-Finges has been officially protected since 1997, after it had already been included in the KLN inventory in 1963 (Inventory of the landscapes and natural monuments of national importance to be preserved).

Rightly so, because the Forest of Pfyn-Finges is not only one of the largest coherent pine forests in the Alps. It is also home to the most important floodplain reserves of Switzerland and is an amphibian spawning area of national importance. With its unique and multifaceted flora and fauna, it is THE biodiversity hot spot of the Pfyn-Finges Regional Nature Park.
