The “Étang de la Gruère” is a dammed, but natural moor lake situated in a hollow on the highland plateau of the Franches-Montagnes in the canton of Jura.
Barren high moors, flowery low moor bogs and a primeval moorland delight the senses! Moors - as far as the eye can see and your feet will carry you. Nowhere else in Switzerland are there so many nationally protected moors in such a small area as in the Entlebuch.
If you hike the Amden mountain trail, via a road section leading to Hintere Höhi you will reach protected moorland: a marshy natural landscape of national importance covered with mountain pine.
