The Isengrindfall is a very tall waterfall at the end of the Weisstannental near Mels in the region Sankt Gallen, Switzerland. The Isengrindfall drops down in a single drop over 230 meter. Especially early in the summer the waterfall is impressive to see.
From Mels drive into the Weisstannental to Weisstannen. There cross the bridge and go right onto a narrow road. After a few kilometer the road ends at a house and parking (gps 46.967617, 9.270578).
From the parking you already have a good view on the Isengrindfall. A little further you also can visit another waterfall called Unterer Mattbachfall.
The Weisstannetal is anyway a very thankful valley if you want to visit waterfalls. There are dozens of unnamed waterfalls but also seven named waterfalls.
