Grebenzen, Mountain summit in Murau District, Austria

Grebenzen is a mountain summit on the border between Styria and Carinthia, standing at 1,892 meters. Its three distinctive peaks dominate the landscape and can be seen from numerous viewpoints across the surrounding area.

The name Grebenzen is recorded around 1400 as "die alwen Grabenzen", in 1468 as "Grebenczalm" and in 1494 as "Krawenzen". It is of Slavic origin, derived either from *kravьnica (cow alp) or *grebenьcь (ridge mountain). The ski area on the north side was founded in 1966.

The name Grebenzen is Slavic in origin, recorded around 1400 as "die alwen Grabenzen" and in 1468 as "Grebenczalm"; it is derived from *kravьnica, meaning cow alp, or *grebenьcь, meaning ridge mountain. The Grebenzenhaus at 1,648 m and the Dreiwiesenhütte at 1,770 m serve as mountain huts along the routes.

The mountain is accessible via several hiking trails, with a mountain hut at 1,660 meters offering food and shelter. Visitors should bring sturdy footwear and weather protection, as the terrain is exposed.

Around the highest point lie several karst caves; the largest, the Wilde Loch, opens at about 1,800 m and was already mentioned in 1673 in the monastery history of Pater Oddo Koptiks. Its first descent, on 29 July 1856, reached a depth of 33 m and yielded the skulls of a red deer and an elk. Bat counts there have recorded 13 species.
