The Grossbachfall is a waterfall in the Umbaltal near the town Hinterbichl in the region Tirol, Austria. The Umbaltal is part of the National park Hohe Tauern with its many waterfalls.
From Matrei in Osttirol you have to drive west, into the Virgental, until the road ends at a big parking lot in Stroden, west of Hinterbichl. In summertime you have to pay a fee, euro 5,50 (2014).
From the parking lot it is a 20-30 minute hike until you reach the Islitzer/Pebellalm where you will have a beautiful view of the gigantic Kleinbachfall. From here the walk along the Umbalfalle starts, further into the valley. There are several manmade viewpoint to see the Umbalfalle. After a few minutes you will arrive at the Grossbachfall which falls down the mountains at the left side.
From the bridge over the Grossbach you have a good view on the Grossbachfall which in summertime is quit powerful. Therefore summertime (July) is the best season to visit the Grossbachfall. The river Grossbach cascades down the mountains over 120 meters before it ends in the river Isel (Umbalfalle).
Best daytime to visit the Grossbachfall is midday when the sun is high in the sky and the sun shines on the waterfall. The Grossbachfall falls towards the north and you will be photographing towards the south, into the sun.
I visited the waterfalls of the Umbaltal twice. First time was in the beginning of May end the second time in August. In May there is still a lot of snow and the rivers aren’t filled with melted snow yet.
