The Schwarzenbach rises at the Weißhorn and flows on the outskirts of Auer into the Etsch. For a long time it was a danger to Auer because floods occurred again and again. The waterfall in the Schwarzenbachklamm is very beautiful.

The Bletterbach is a watercourse located in the area of the municipality of Aldine and forms the Bletterbach gorge at the foot of the 2,316 m high Corno Biano, also known as the "Grand Canyon of South Tyrol". The gorge, which was formed about 15,000 years ago in the ice age, is about eight kilometers long and 400 meters deep. It has been slowly sculpted by water erosion, making different sedimentary layers visible. In addition to the geological interest, the Bletterbach Gorge offers a unique landscape. It is impressive to walk between the steep walls of the gorge. Access is allowed only with a protective helmet and the entrance to the park is paid but it's worth it.
