Katerloch

Highlight • Cave

“Fantasy Hall”, “Sea Paradise” and “Magic Kingdom” are the names of the underground halls here, with their unimaginable wealth of stalactites, like something out of an oversized script. Austria's show cave with the most stalactites can be explored over a path length of around one kilometer via serpentines, massive iron stairs and 400 steps with a height difference of 135 meters.

An imposing cave portal leads to the inwardly sloping entrance hall with mighty mossy sinter columns overgrown with algae. In the 120 meter long and up to 85 meter wide “Fantasy Hall” there is a veritable jungle of around 4,000 large stalactite structures. From here you can reach the “Magic Kingdom” and the “Sea Paradise”. At the lowest point, alabaster-white stalagmites and sinter islands grow up from the shimmering turquoise-green water surface, framed by magnificent bank walls.

Opening hours: From April to November by prior arrangement by telephone (+43 664 48 53 420).

Admission: 20 euros per person, minimum number of 9 people, an additional charge applies for fewer people. The tour lasts about two hours.

A protected cave that is not allowed to be entered because bats live in it. From the cave the path is no longer marked according to the sign and it continues alpine.

Very varied trail, a few caves, deep views, mostly rather uneven - surefootedness is a must. Publicly accessible by bus: Naas Felsenkeller stop Public transport tour report: https://www.bahn-zum-berg.at/randgebirge-oest-der-mur/jaegersteig-weizklamm/
