The nature trail "NaturKraftWeg Umbalfälle" at the end of the valley Virgental leads very close to the source of the glacier river Isel and shows its landscape-forming effect and its character in an impressive way. Especially in the summer months, when the glacier melts, impressive masses of water thunder down to the valley. Along the circular route, there are not only interesting information boards, also visitor platforms make the unbelievable natural force of the water directly tangible, whether high above the gorge or up close to the water.
Access is not possible during the winter months!
