Einhornhöhle ("Unicorn Cave")

The Unicorn Cave (German: Einhornhöhle) in Austria is situated in the Hohe Wand Nature Park near Dreistetten in Lower Austria and may be reached on signposted hiking trails in ca. 20 minutes from Dreistetten (typical signpost illustrated). The cave was discovered in 1927 by Otto Langer senior and opened as a show cave in 1930. In 1964 the structures built by Otto Langer junior were modernised. Guided tours that take about 20 minutes are laid on from Easter to the end of September on Sundays and public holidays.
