The first 850 metres in altitude to the Leiterli top station are gained by means of the Betelberg cable car, where the unique high-altitude trail through the Gryden area starts in a leisurely manner. In view on the first section: the protected, alpine moor landscape of Halserberg/Betelberg. Before the mountain trail narrows and the first ascent begins, it is worth stopping for a break at the Steinstoss alp which you will pass again on the way back.

The following easy ascent runs along the south side of the Stübleni limestone formation, the highest point of the hike. On a clear day, you can enjoy a fantastic panoramic view: from the Simmental over the Saanenland to the mountain gems of Fribourg. The "Stübleni" (small rooms) refer to the individual "craters" in the Gryden area, whereby "Gryde" probably comes from Chride (chalk). But how did this unique area in Switzerland, which fascinates geologists, biologists and hikers alike, come into being? The rain gradually dissolves the almost white, relatively soft gypsum rock. The water carves holes in it, but continues to flow underground, creating a system of gypsum karst with cavities. When one of these collapses, the sinkholes become visible on the surface. In the Stübleni area, these seepage funnels are particularly numerous.

The trail winds downhill past the sinkholes towards the turning point of the circular hike. A detour to the refuge is worthwhile here: take a break and enjoy the moon-like crater landscape before heading back. Those who do this additional loop should be sure-footed and free from vertigo. This time you pass the "Stübleni" to the north. From there, the trail descends steadily to Steinstoss, after which there is only about one kilometre left to reach the starting point.
