Hochstein (also known as Sibyllenstein) is a small, forested mountain in the district of Bautzen in Saxony, southeastern Germany. With an elevation of about , it is described as the highest summit of the North-West Lusatian hill country (Nordwestlausitzer Hügelland).
The mountain lies east of Pulsnitz and near the town of Elstra.
Hochstein forms a prominent wooded summit within the gently rolling uplands of West Lusatia. The surrounding relief is characterised by a dense pattern of short valleys and ridges typical of the West Lusatian hill country.
The summit area includes exposed rock formations; the traditional name Sibyllenstein is associated with these outcrops and local tradition.
The wider region belongs to the Lusatian basement and is characterised by intrusive rocks, including varieties of granodiorite documented for eastern Saxony. A major geological structure of eastern Saxony is the Lusatian thrust (Lausitzer ÃÂberschiebung), separating the Lusatian crystalline complex from younger sedimentary units of the Cretaceous basin to the south and west.
The Black Elster river rises on the Hochstein above the locality of Kindisch in the Upper Lusatia region.
Hochstein is a local hiking destination. Marked walking routes connect the summit area with nearby villages and points of interest in the West Lusatian landscape protection area.
Early 20th-century regional literature describes the Hochstein/Sibyllenstein as a notable viewpoint and records local traditions connected with the summit rocks.
