The Krimml Waterfalls or waterfalls of Krimml, with a total height of 380 metres (1,247 feet), form the highest waterfall in Austria
. The falls are formed from the Krimmler Ache river and are located near the village of Krimml in the High Tauern National Park in Salzburgerland.
Krimmler Wasserfälle is a tiered waterfall. The waterfall begins at the Krimmler Ache at the top of the Krimmler Achendal, 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 Krimmler Ache is a glacial stream whose flow varies greatly with season. The 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 Danube River and finally to the Black Sea.
