Beautiful trail, physically challenging, with Schwarzsee as central point.
Beautiful panorama. First loop around the Hochmattli beginning by a difficult ascent on a asphalted mountain road following by a descent to Schwarzsee on a gravel road. Second loop : long ascent on a 4x4 road then on a path to la Balisa and la Patta, followed by a beautiful singletrail on the ridge of Schwyberg. Nice descent and return by the path bordering the "warm Singine".
