Another attraction worth visiting was not created by builders but by nature: the Barbian waterfalls. The Ganderbach (stream), which is near Kollmann and flows into the Eisack river, 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 is 85 metres at its highest. From here, you can reach the upper part of the waterfall via a marked, wild and romantic path.
