The Berschnerfall is a nice looking waterfall with a single drop of appr. 30 meter, but I have read that the total height is 46 meter. The Berschnerfall is located near the village of Berschis in the region Sankt Gallen, Switzerland.
When driving from Zürich to Chur on road 3 take the exit 49 Flums. At the end of the exit go Left to Mels and then at the roundabout follow the signs Berschis. In Berschis take the first road right. Park the car somewhere near the church and walk towards the mountains to a place called Muhle/Mulli which means Mill. Here you have to follow the Berschnerbach (river) upstream for 15 minutes. Stay at the left side of the river until you reach a bridge in front of the Berschnerfall.
Here you have a good view on the Berschnerfall with a single drop of 30 meter. Most time of the year the volume is quite respectable but I like the early summer for visiting waterfalls.
