Oberalp Pass: The Oberalp Pass - called "Alpsu" in the Romance language - is the connection between Disentis in the canton of Graubünden and Andermatt in the canton of Uri. The highest point of the pass road is located at 2,044 m above sea level.M. The pass road measures a length of 32 kilometres from Disentis to Andermatt.  In the Middle Ages, the pass gave Graubünden access to the pig and goat markets in the cantons of Uri and Ticino.

Due to the construction of today's road in 1862/63, traffic over the Oberalp experienced a great revival. The stagecoach romance emerged. The carriages did not disappear until 1925, when the automobile was introduced in Graubünden. The road is only passable during the summer.

Lai da Tuma/Lake Toma: The 1,230-kilometre journey of the Rhine begins at the source of the Rhine. Much of what happens here has an influence on its course. That is why the inhabitants of the municipality of Tujetsch - on whose soil the source of the Rhine lies - take care of their natural wonder. The mighty Vorderrhein glacier covered the entire Surselva during the last ice age. The mountain landscape of the Oberalp Pass, formed by Gletschen, is the source area of the Vorderrhein. The ice stream has long since melted, leaving behind is a firn hollow in which the Lai da Tuma, at the foot of the Piz Badus, is embedded. A jewel among the Swiss mountain lakes at 2,345 m above sea level.M. - unique in its beauty, magic and significance.


In July, the alpine roses and the sweet-smelling Turkish bunch bloom along the way.

At the beginning of the tour we walk along the pass road 10 minutes downhill. We cross a small stream and now follow the high-altitude path south into Val Maighels. At point 2056 we turn right and it goes up in a zigzag. First we hike over alpine pastures, a little later the path becomes steeper and rocky. As soon as we have passed the last bends we reach the lake. The way back is on the same route.
