The area's most beautiful and delightful hike over the mountain ridge that links the Heinzenberg with the Safien valley, offering spectacular views of both valleys.
From the starting point at Obertschappina the route follows the Walser Trail to the tree line up on the Glas Pass. From the historical crossing point into the Safien valley the route winds its way across steep mountain pastures up to the Glasergrat ridge. The views across both valleys are impressive. Next comes the descent to Valdiena-Lucka and on to Lüschalp. The lake of Bischolsee with its picture postcard motif is enticingly close as is the lake of Pascuminersee, with the promise of a refreshing dip.
The trail continues up via Alp Bischola to the highest point on the hike at the Tguma at 2163 m, another highlight with incomparable panoramic views of the Graubünden mountain scenery. The narrow panoramic trail across the Heinzenbergergrat ridge provides the connecting link with the Präzer Höhi. The descent to Präz is via the Alp Gronda.
