About Lurgrotte#
Lurgrotte is a karst cave system in the Austrian state of Styria and is among the country’s largest known cave complexes. The system includes showable passages and parts that have been explored for scientific study.
Guided tours run through the main accessible passages and highlight stalactites, stalagmites and other karst features; the cave also contains an underground stream whose flow can affect accessibility. Visitor routes focus on the dry, developed sections that are safe for public access.
Exploration and mapping of the cave system expanded during the 19th and 20th centuries, and the site has long been of interest to speleologists and geologists. Management balances public access with conservation of fragile cave formations.
Lurgrotte is located in central-eastern Austria in the state of Styria and is reached from local roads that connect the cave to nearby towns and to the regional city of Graz.
- Two entrances and river: The cave system has two main entrances and an active underground stream; parts of the system are only accessible when water levels are low.
