Schneckenlochhoehle, Limestone cave in Vorarlberg, Austria.
Schneckenlochhoehle is a limestone cave in Vorarlberg that extends for 3500 meters through rock formations with numerous passages. These tunnels follow the geological boundaries of the Helvetikum rock series and create a complex underground network.
The cave was first documented in a newspaper article around 1900 and officially recognized as a geological natural monument in 1955. This designation marked the site's importance for scientific research and protection of the underground landscape.
The cave serves as a research site where geologists and speleologists study karst landscapes and the underground water systems that carved these passages.
Guided tours last about 5 hours and require visitors to wear hiking boots and bring appropriate gear for underground exploration. Participants must be at least 10 years old and in reasonable physical condition since the passages can be uneven and sometimes narrow.
The cave serves as a winter shelter for bat species such as Myotis myotis and Myotis daubentonii during cold months. This makes seasonal access restrictions necessary to protect the roosting animals from disturbance.
