The raft access in Huben is around 300 m above the town of Huben (right on the B108) and is signposted by information boards. From here it is initially very turbulent (IV), beneath the bridge to Kals, through to the influx of the Schwarzach. From here a 500 m wonderful natural slalom awaits paddlers up to the influx of the Kalserbach. Since this section is lovely but also very short, you should combine it with the previous or subsequent section. See Brühl-Huben or Kalserbach-Ainet.
