Which is the highest waterfall in Austria?

The Krimml Waterfalls with a total height of 380 metres (1,247 feet), are the highest waterfall in Austria. The falls are on the Krimmler Ache river and are located near the village of Krimml in the High Tauern National Park in Salzburg state.

Krimmler Waterfalls is a tiered waterfall. The waterfall begins at the top of the Krimmler Ache valley, and plunges downward in three stages. The upper stage has a drop of 140 metres, the middle of 100 metres, and the lowest a drop of 140 metres. The highest point of the waterfall is 1,470 metres above sea level.

The Krimmler Ache is a glacial stream whose flow varies greatly with season. Its volumetric flow in June and July is 20,000 m³/h (about 5.28 million gallons per hour), while in February it is only 500 m³/h (about 0.13 million gallons per hour). The greatest measured flow was on 25 August 1987, when it was 600,000 m³/h, or almost 160 million gallons per hour.

After the falls, the river joins the Salzach, which flows to the Inn, then into the River Danube and finally to the Black Sea.
