The Schlierertal valley plateau is an insider tip for nature-lovers: the Langis area is served by the PostBus from Sarnen and offers some 50 kilometres of groomed cross-country skiing runs. It is located directly at the top of Glaubenberg Pass, which leads into the Entlebuch region. It is about 300 metres from the car park to the starting point for all the runs, which you can cover wearing your skis. Once you have overcome the gradient with an elevation gain of 20 metres, you have the entire cross-country skiing area at your feet. As you look up, the dominating mountains are Titlis, Hochstollen and the Wetterhorn peaks.

The Pirmin run towards Fröschenseeli is somewhat flatter in the first half, covering lightly wooded terrain. It first passes the Andresenhütte cabin to Schwendi-Kaltbad with the Holy Virgin Chapel. This commemorates the “cold bath in the Schwendi”. At the beginning of the 17th century, a shepherd boy is said to have seen a limping deer dipping its leg into the water; when the animal pulled its leg out again, it was perfectly healed. Over the years a well-known spa resort was established that attracted more and more sick people hoping to heal their ailments at this source, which is rich in iron. The famous spa hotel burned down in 1970. An outbuilding was converted into a Beizli refreshment hut in the style of a Canadian log cabin.

Before the skier earns a break, the run loops three more times and then crosses the River Schliere. There is then a climb followed by a leisurely section, with the option of a stop-off at the Schwendi-Kaltbad. From here to the finish it is another two kilometres.
