De Gurmels à la réserve de l'Auried
The purpose of our hike is the Auried swamp zone, an amphibian reserve of national importance.
From Gurmels, follow the marked hiking path "Schiffenenen-Staumauer". At the entrance of the dam, turn left and start the descent to find the Sarine river at the foot of the imposing retaining wall. A pleasant path runs along the river to the Auried reserve. The reserve is home to one of the largest populations of tree frogs in Switzerland. On spring evenings, the place is the scene of a deafening concert of more than two hundred males whose singing exceeds ninety decibels. The biotope is home to other amphibians, several species of birds and ducks, dragonflies, many invertebrates and a beaver family. To return, take the route that passes through Kleinbösingen and Grossholz.
Tip: The Chorus Frog is considered a highly threatened species as its habitats are increasingly being destroyed. It is therefore a protected species.
