The Radniger wasserfall is a low volume waterfall just north of Hermagor, near Radnig, in the region Kärnten, Austria.
From Hermagor drive to Radnig. Drive to hotel aktiv Karnia and further on to the natur schwimmbad (gps 46.644617, 13.363997). A few hundred meter further go left (I am not sure if this is possible) and drive up the road until the meadow stops at your left hand. At the right there is a small parking and also the trailhead up to the Radniger wasserfall.
In 10 minutes time you can reach the base of this low stream waterfall.
