A ravine near St. Andrä-Wördern. Hiking trail along a stream called Hagenbach. At the end of the ravine is the largest breeding station for birds of prey in Europe with over 30 species of birds.
The Hagenbachklamm is a ravine in the municipality of Sankt Andrä-Wördern. It was carved out by Hagenbach, a small tributary of the Danube. It is about 1,300 meters long. The ravine runs from south to north and is within Eichenhain Nature Park.
The ravine subsoil is soft sandstone, a material into which even small streams can easily dig. There are few rocky cliffs in the ravine because of the softness of the stone. They collapse soon after they form. As a result, most of the ravine is bounded by steep slopes covered with plants. Sandstone cliffs can be seen at several places where the sandstone is a little harder.
A well-tended and popular hiking trail goes through the ravine. There are inns at the upper end of the ravine in Hintersdorf and Unterkirchbach, both parts of the municipality Sankt Andrä-Wördern. The entry to the ravine can be reached on foot, by public bus or by car and is about a kilometer to the south of Sankt Andrä.
