The source of the Adranser Bach is in a forest near Aldrans. It flows in northern direction to Ambras Castle. In the past, there was a public swimming pool that was fed by the Aldranser Bach. In the park of the castle the Aldranser Bach supplies the Grand Pond with fresh water and then flows further through Small Pond and the castle's park to Ambras, where it merges with the Lanser Bach that flows into the Inn River. The Aldranser Bach has a length of about 7 kilometres (4.3 mi).
Water quality
Due to the fact that the rives flows through forest areas, it has a high water quality. The self-purification of the water is still intact. In winter the Aldranser Bach prevents the total freezing of the Grand Pond, which is good for the many rare water birds and fishes. The Grand Pond is a small lake where many seldom birds breed and live.
Flora and fauna
Even if the river is small, it provides rare birds such as peacocks, herons around the castle's park, a protected habitat. In its upper course, the river is too small for fishes; they can be found in the lower course as well as in the pond. The river also flows through a narrow ravine named Schönruh with a small waterfall.
