The Äsch Alp with the approx. 100 metre high spray waterfall is among the biggest natural spectacles in the Urnerland.
From Unterschächen, Äsch is accessible on a tour by foot within just under an hour. The ornate chapel in Äsch was restored and extended in 1982/83. A path leads further on from Äsch through the steep Balmland to the Klausenpass.
