The Hochlantsch (1,720 m (AA)) is the highest mountain in the Graz Highlands, a subgroup of the Prealps East of the Mur according to the Alpine Club classification of the Eastern Alps.

The Hochlantsch is a popular destination for those living in the Graz area due to its good views and easy access.

The easiest ascent takes about two hours and starts at the Teichalm.

From the pub of Zirbisegger (accessible from Breitenau by car) the Friends of Nature Klettersteig (Naturfreunde-Klettersteig) runs up the rocky northern flank to the top.

Nearby are the inn of zum Steirischen Jokl and the little pilgrimage church of Schüsserlbrunn.
