Austria’s largest water-active flowstone cave

The Lurgrotte Peggau located about 20 km north of the state capital is an easy to reach, popular destination in the Graz region.

A meltwater brook brings the subterranean labyrinth of the Lurgrotte to life.
This cave is known as a natural wonder, not only due to the force of water that has been enlarging the cave for millennia, scouring the stone into unique shapes, but also because of this element’s tenacity.

Secure concrete trails take you one kilometre deep into the world of stalactites and stalagmites during the one-hour tour.

The Lurgrotte Peggau is not only an ideal bad weather activity for bus tours, but especially a refreshing change on hot summer days:

  • it has a temperature of + 10 degrees Celsius all year long,
  • with almost 95% relative humidity

Guided tours

During a guided tour of the Peggau Lurgrotte, you will either be taken 1 kilometer (one-hour guided tour) or 2 kilometers (2-hour guided tour) deep into the cave. With electric lighting or LED lamps you can walk through the caves. Here is a special atmosphere to advantage.

If you want, you can bring your own lamps, but no torches and oil lamps. The visitor has access to a newly designed cave museum (site of a Neanderthal camp), Wi-Fi hotspot and a visitors' lounge with photos and information.
