Ludwigfall, Waterfall in Lower Austria on the Seebach

The Ludwigfall is a waterfall located above Lunz am See in Austria that connects two lakes, the Obersee and Mittersee, dropping about 60 meters down a steep rock face. Water flows continuously from the upper lake with force, creating a loud roar and sending spray into the air as it falls.

The waterfall is named after Archduke Ludwig of Austria; the source gives no date for the naming. It links the Obersee with the Mittersee, and the stream below continues into the Mittersee and then down to the Lunzer See in the valley. The name is the only historical element the sources record for the site.

The waterfall's name honours Archduke Ludwig of Austria. The route from Lunz am See past the Lunzer See up to the Obersee is a long-established hiking path, and the falls are passed on the way to the Mittersee and Obersee. Experienced hikers continue from the Obersee over the Herrenalm to the Dürrenstein and on to the Ybbstaler Hütte.

The path to the waterfall follows well-maintained forest roads from Lunz am See past the lakes toward the Mittersee and Obersee, with the final stretch open only to foot traffic as vehicles cannot pass. The walk to reach the falls takes about one and a half to two hours for the last six kilometers and is manageable for most people with basic hiking gear.

The waterfall drops 60 metres from the Obersee into the Mittersee, and the stream then continues down to the Lunzer See in the valley. From the Obersee, experienced mountain hikers can continue over the Herrenalm to the summit of the Dürrenstein and on to the Ybbstaler Hütte, returning to Lunz am See the next day via the Wolfsklamm and the Lechnergraben.
