An extremely cool T2 (T2+) trail in the Mülitobel gorge, climbing along the babbling and rushing Tobelbach stream. A non-critical section is secured by ropes. The cave, however, is merely a pronounced rock overhang.

Wichensteiner See, Oberriet The Wichensteiner See is located in the municipality of Oberriet at the eastern foot of the Semelenberg. A clay pit operated on the area of the present lake from 1830 to 1972. The lake lies at an elevation of 420 meters above sea level and has a maximum depth of approximately 5.5 meters. It is divided into a smaller northern basin and a larger southern basin. The area was acquired by the municipality of Oberriet in 1976 and declared a nature reserve in 1982. East of the lake lies the "Grube Loo" (Loo Pit) – also a former clay pit – which, together with the Wichensteiner See, is a fen of regional importance and an amphibian spawning area of national importance. The lake is fed, in addition to underground springs, by the Wichensteinerbach stream, which drains the northern foot of the Semelenberg. The outflow structure leads into the Aubach stream.
