St.-Gotthard-vier-Pässe-Bike

A train takes you up from Andermatt to the hamlet of Nätschen. If you look back here, you can see the Ursern Valley again, with its many green areas, the Gurschenwald forest and the striking Bäzberg on the right side of the valley. At the very back of the valley, you can see the Muttenhorn which is in the Furka area. On the right side of the valley, the trail runs past the alpine pastures of Seeplangg and Schöni. From the left bank of Lake Oberalp, the rugged rock faces rise up in the Schneehüenerstock area. The lake is in the idyllic setting of the alpine landscape and is home to brown trout and rainbow trout as well as arctic char.

The Oberalp Pass is 2,044 metres above sea level and connects the cantons of Grisons and Uri. Far from an ocean, the only lighthouse in the Alps stands here. It symbolises the source of the Rhine, which rises nearby. The ten-metre-high tourist attraction is a replica of a real lighthouse that once stood in Rotterdam at the mouth of the Rhine.

Three kilometres south of the pass is Lake Toma, the source of the Rhine. The outflow from the lake is called Rein da Tuma. Beyond the first two valley levels before Tschamut, this and other tributaries become the Vorderrhein. The trail plunges into the remote Val Vorder Rhein via the Tiarms Pass. Three more valleys follow, alternating upwards and downwards: Val Giuf, Val Mila and Val Strem. They are all known for their rich mineral deposits. The destination for this stage is Sedrun, the main town of the Tujetsch.
