Grasslhöhle

The Grasslhöhle extends deep into the mountain, featuring numerous chambers decorated with white stalagmites, stalactites, and flowstone formations throughout its passages.

After its initial discovery centuries ago, the Grasslhöhle became accessible to visitors in 1952 when Hermann and Regina Hofer installed electric lighting systems.

The cave forms an integral part of the Naaser cave trail system, connecting multiple geological formations across the Eastern Styrian landscape.

Guided tours of the cave operate from April through October, with daily access during summer months and weekend-only visits during spring and autumn.

The cave contains a massive formation called the Giant, measuring 3 meters in width and reaching 10 meters toward the chamber ceiling.
