Between Rothenthurm and Biberbrugg lies one of Switzerland's largest upland moors, whose wetlands and bogs are considered sites of national importance. A moorland path runs through the middle of this precious landscape.
These idyllic ponds in the north-easternmost part of Ajoie between Bonfol and Vendlincourt provide a habitat for distinctive species of plants and small animals rarely found in Switzerland.
The Chaltenbrunnen raised mire is located on a slope terrace above Meiringen. Because it has remained in its original unspoiled state, it is one of the most important mires in the Swiss Alps.
