Signposting: Alpenpässe Weg -- Alpine Passes Trail Signposts with green stickers No. 6 (white-red-white markings)
(S) From the Hotel Schwarzhorn, follow sign No. 6 indicating the Augsbordpass. Walk through the forest at first. After numerous hairpin bends, you will gradually reach the Grüobu stable.
(1) Continue the ascent to the Augstbord Pass, crossing the Grüob valley (Grüobtälli) in a very rocky landscape.
(2) Take a well-deserved break at the pass. Begin the descent into Inners Tälli, alternating between scree and boulder fields. Follow the numerous white-red-white markings. Continue on an almost flat path to the Twära ridge.
(3) Begin the descent and reach the Undri Läger mountain pasture. Stay on trail No. 6, turn east and reach the hamlet of Jungu.
(4) Cross the hamlet and follow the Alpine Passes trail (green No. 6 signs) down to Sankt Niklaus. Cross the railway line, follow Bahnhofstrasse, then Dorfstrasse to return to the Heimatlodge Hotel, your accommodation for the night (E).
