Along the spectacular Suone Wyssa, this hike first takes you from Mund along steep rock faces and through 16 tunnels to the stony meadows of the Gredetschtal. The Wyssa was first mentioned in a document around 1462 and its builders had to attach it to the rock under difficult conditions.
In 1928/29, the Suone was renovated and its course was partly relocated into tunnels; in 1998, a modern water tunnel was built. This is located next to the entrance to the Suonenweg and is an alternative for hikers who are afraid of heights.
The hike back to Mund first follows the Mundbach stream and then turns off onto the Suone Stigwasser. With a minimal descent, it goes along the Suone back to the starting point of the hike.
The irrigation channels, some of which lead through spectacular terrain and steep rocky sections, are both located in the Gredetschtal valley near the Mundbach stream at about 1,300 m above sea level and were used for a long time to irrigate the fields and meadows in Mund and Birgisch.
Note
The trail leads along the bisses, sometimes along steep cliffs, and should therefore be walked with caution; a head for heights is required. Younger children should be roped up. You walk through several narrow tunnels, which is why a torch is useful.
