Schraubenfallhöhle is a cave, an underground river. It starts from one raging waterfall of the Tuxbach dropping into a wide hole in the ground, and emerges a bit later to start another waterfall. It is located by the end of the Hintertux valley, right by the lowest lift station taking people up to the Hintertux glacier.

You can read more about this cave (in German) from this research article, "Die Klamm des Tuxbaches bei Hintertux (Tirol) und das Alter der Schraubenfallhöhle", appeared in Die Höhle in 1967, issue 018. The article is by Hubert Trimmel.

Entering the cave is impossible, as it is maybe fifty meters down in a deep gorge. I'm not sure if the cave is otherwise visitable, perhaps during dry seasons and when not much meltwater is coming down from the mountains. The article referred to above seems to describe what's inside the cave, so people have been there.

I was therefore not in the main cave, but visited a couple of tiny caves on the side, though Austrians would probably not call these caves at all. Just a few meters long, enough space for one person. The first side cave map is here, a rotatable 3D model here, and the model can be downloaded here. The second side cave map is here, a rotatable 3D model here, and the model can be downloaded here.
