Another important attraction was not created by builders but by nature: the Barbian waterfalls. The Ganderbach (stream), which is near Kollmann and flows into the Eisack river, which has a length of almost 6 kilometres. At the point of 1,510 metres above sea level, the stream falls over several rock cliffs down into the valley. The lower part of the waterfall with his 85 metres is the highest of the waterfalls at Barbian. From here, you can reach the upper part of the waterfall on a marked, wild and romantic path.
