Gasteiner Wasserfall, Waterfall in Bad Gastein, Austria.

The Gasteiner Wasserfall is a three-tier waterfall on the Gasteiner Ache in the centre of Bad Gastein, Salzburg. Its total drop is 128 m, the tallest single step 56 m, making it Austria's seventh-highest waterfall. The stream rises in the Hohe Tauern National Park from the Anlaufbach and Naßfelder Ache and leaves the Gastein valley to join the Salzach.

The waterfall area was first developed in the early 19th century, and a stone bridge built in 1840 provided the first proper infrastructure for access. This bridge was expanded later and remains part of the historical connection to the falls.

The falls appear in Hermann Burger's story "Die Wasserfallfinsternis von Badgastein", about a night porter who believes he has found a lost Schubert symphony at the bottom of the waterfall. An excerpt won Burger the Ingeborg-Bachmann-Preis in 1985. The waterfall was also a subject for painters and poets.

The path to the waterfall, called Wasserfallweg, is usually open from spring through fall but may close during winter months due to snow and ice. Wearing sturdy footwear is important since the paths can become slippery, and it is wise to check local conditions before visiting.

The waterfall's three tiers drop 128 m in total, with the tallest single step at 56 m, making it Austria's seventh-highest waterfall. The Gasteiner Ache gathers its water from the Anlaufbach and Naßfelder Ache inside the Hohe Tauern National Park before the stream reaches Bad Gastein.
