Sliding, briefly also carrying range up the Rossweidhöchi. From there ingenious descent to Niederurner Täli! At the beginning there are two hiking trails open, the one straight down through the forest is harder to drive. Fantastic up here!
I always do the tour from Siebnen - Niederurnen. The descent from the Rossweidhöchi on the old road down to Niederurnen is simply nicer than the reverse tour. The carrying passage is also only 15 - 20min. so well tolerable.
