We orient ourselves at the yellow Wanderwegtafeln with the number 49 and take the way to Tomasee. At point 2065 we ascend in south-westerly direction in some turns to Tomasee. At the outflow of the lake, the hike leads over a newly created stretch of road to the Lai Urlaun. Below the Maighelshütte, the signpost now points towards Val Maighels until the turnoff at the Plaunca Purtgera to Maighelspass. We hike on a zigzag path down to our destination of the Vermigel Hut.
We start at the Vermighel hut in the direction of Sellapass and continue to the highest point of the Vier-Quellen-Weg, the Piz Giübin (2776 m). The descent is via a crete overlooking the Val Canaria to Madrano and Airolo. Below the Posmeda pass, we take the direct route to the dam. The last stretch is on a road. The "Albergo San Gottardo" is located directly on the famous Tremola.
We leave the Gotthard hospice and walk a few minutes past the fort "Fort Hospiz". The path crosses the pass road and continues to the dam wall of Lake Lucendro. At the Alpe the Lucendro, the trail climbs gently at first, then progressively steeper under the flanks of the Pizzo delle Valletta. Then we cross a small valley and are suddenly in front of a lake, which is the source of the Reuss. The path climbs gently uphill again to the Lucendropass. First along the southern flank of the Fibbia and later on a steep zigzag path we descend to the Alp Rosso di Fuori. We are now on the "sentiero alto Bedretto". On this wide trail we pass the Ri di Cavanna, Ri di Bedretto and Ri di Ronco. From Alpe Pesciora we reach in less than an hour our destination, the Piansecco hut.
From the Piansecco hut, stay on the Sentiero alto Bedretto until the Nufenen Pass road. Below the road our hiking trail leads down to the alpine huts at the Postautostation "Cruina". We now tackle the hike to the Nufenen Pass and reach a small tributary of the Nufenen Pass. After a short descent you come to the road that leads to the Griespass with its distinctive dam. Now we follow this wide road to the Griessee and then reach a turnoff that leads down into the valley. We get off and come to the so-called "Sbrinzweg". The mule track leads down to Nufenenstrasse. Below Aarena you reach a hilltop and look into a wild ravine. On a solid suspension bridge we cross the river. Then it goes through a forest down to Alpweide Kitt, where you cross the pass road. After crossing a wooden bridge we are standing at the first houses of Ulrichen. Whoever is aiming for Obergesteln, wanders into the valley in the direction of Rotten and Golfpaltz.
On a wide trail along the Rhone we reach Oberwald. At the first branch after the Rottenbrücke we go to the left and pass under the Matterhorn-Gotthard-Bahn. Passing the St. Nicholas Chapel and partly along the Furka Steam Railway, in the upper part of the road, we reach a roped-up jetty, which zigzags down to the rump. Along the stream, you will ascend to the portal of the steam tunnel's spiral tunnel. Via a staircase you finally reach the pass road and follow this a few meters out of the valley. Then you reach the trail back to Gletsch. Past the "Blue House" we walk across the plain of the glacier floor. Afterwards it goes down from the edge, where we then climb obliquely to the route of the steam train. We now cross the railway track and take the path towards the Muttbach bridge at the Oberalpenstafel. Now we have a sweaty climb through many hairpin bends up over the Rossboden to Furkapass before. On the Furkapass we cross the road and climb a few minutes in a westerly direction on a hill. Then it goes on a well-developed path down rough terrain with many granite blocks, and we reach a summit with a magnificent view: namely our destination, high above the Rhone spring. We do not go straight to the source of the Rhone, but look at it from high above.
