Source of the Rhine – Lai da Tuma

Highlight • Lake

From here, along the stream, you can also return to the OberalpPass. The path is a little longer, but not that steep. You can also see the high moor area with streams and meadows, and the Plidutscha plateau with maga views .....

Oberalp Pass

Highlight • Mountain Pass

At the Oberalp Pass at 2,044 meters, not only is the obligatory "passport photo" waiting at the Oberalp Pass sign, but also the only lighthouse in the Alps. It comes from Rotterdam, where the original lighthouse can be found in the Maritime Museum, which once stood in Hoek van Holland, at the mouth of the Rhine into the North Sea - thus completing the circle from the source to the mouth.

Lake Oberalp

Highlight • Lake

Here, where the world's highest lighthouse stands, begins the hiking trail to Lake Tomasee (2,344 meters), considered the source of the Rhine. From here, it's just 200 meters in elevation to the Badushütte, where you can relax and unwind.

You can also take a cable car from the Oberalp Pass to the Schneehüenerstock, which is over 2,600 meters high, and explore various hiking trails there.

And those who aren't so good on their feet can bring their fishing rod and fish in the lake or simply enjoy coffee and cake on a terrace.

Lukmanier Pass

Highlight • Mountain Pass

The Lucomagno is one of the most famous Alpine passes in Switzerland. It is located between the cantons of Ticino and Grisons, at an altitude of 1,926 meters. The name seems to derive from the Latin "locus magnus", meaning "large, open place". It is often tackled in the professional race of the Tour of Switzerland.

Lukmanier Pass summit

Highlight • Mountain Pass

Lukmanier Pass
When the Disentis monastery was founded around 720, the Lukmanier Pass, which could be crossed without great difficulty and was also considerably lower than the other passes in the Alps, became very important. During the Staufer period, it was considered the most important north-south connection to Italy. However, it quickly lost this role to the Gotthard and Splügen passes. In 1374, the Disentis monastery built the "Hospezi S. Maria" with a chapel on the top of the pass. Both had to make way for the construction of the reservoir in 1964. The new hospice at the current location was inaugurated on August 1, 1965 and the chapel in 1967.
The Lukmanier Pass played an important role in the choice of the route of an Alpine railway at times, because the planners assumed that it would be possible to build it without an expensive summit tunnel. In 1869, however, the decision was made in favor of the Gotthard railway. Between 1872 and 1877, a modern road was built over the Lukmanier. With the construction of the "Lai da Sontga Maria" reservoir in the 1960s, the road on the Graubünden side had to be relocated to a gallery. The importance of a supra-regional transport axis ended with the opening of the motorway tunnel through the Gotthard. Tourism in the Surselva began to suffer greatly as a result, especially as the pass was closed during the winter from 1980 onwards.
On the initiative of the municipality of Disentis and the Surselva mountain railways in particular, the "Pro Lucmagn" association was founded, which has been responsible for ensuring that the Lukmanier pass remains open for as long as possible in winter since 2005. The canton, district, municipalities and tourism in both Graubünden and Ticino provide the finances. The five-year trial phase was positive. This project has been secured for the long term since 2011. Clearly to the benefit of tourism in the Surselva as well as in the Blenio Valley.

Lake Bischol

Highlight • Lake

The elongated Bischolsee, also known as the Bischolasee, is located on Heinzenberg at an altitude of 1,993 meters. The lake is under nature protection and therefore it is not allowed to swim in it. But don't worry, just a few steps away you can hop into the Pascuminersee. The view from the lakefront of the mighty Piz Beverin is simply wonderful and with a little luck the summit will be perfectly reflected in the surface.

Lag da Pigniu Dam

Highlight • Monument

The dam wall of the Lag da Pigniu - or Panixersee - is 270 meters long and was built between 1980 and 1990. In 1999, the artist Martin Valär from the Engadin used the large concrete surface as a canvas. He painted a painting on the wall that was almost 200 meters long and around 30 meters high. The subject: the crossing of the Panixer Pass by the Russian army in October 1799. Unfortunately, the weather has taken its toll on the paint, so that the painting has now faded considerably.

Beautiful hike, about 1.5 hours long. Scenic spectacular and not too strict, this is also a good hike with children! Highlights for children are probably the dam and the old settlement Frunt with the small chapel. After a first ascent to Frunt, the walk leads almost only slightly downhill to the gondola station Gadastatt back to Vals.

June 1, 2025, Lukmanier Pass

Scenic pass that is opened all year round (closes at 6pm in winter). There is hardly any traffic which makes cycling very nice and plenty of opportunities to take pictures. We crossed the pass in early May when there was still plenty of snow up there. The change in scenery where it was all green at Disentis and slowly turning white as we climbed higher... and very quickly turned to green as we rolled down on the south side to Biasca was breathtaking.
