Breitenstein, Mountain summit in Baden-Württemberg, Germany.

Breitenstein is a rocky summit in the Swabian Jura of Baden-Württemberg, rising to around 811 meters and shaped by Jurassic limestone outcrops mixed with patches of dense forest. Near the top, the tree cover thins out and reveals a broad view over the foothills to the north.

The limestone of the Breitenstein formed during the Jurassic period, when a shallow sea covered what is now Baden-Württemberg and left behind layers of sediment over millions of years. In the 19th century, the Swabian Jura hiking association began laying out and marking footpaths across the region, opening the summit to a wider public.

The plateau holds a bronze plaque showing the location and distance of the places visible from it, including Stuttgart to the northwest. The rock face and cave of the Breitenstein are protected as a geotope and as a nature monument, and the outcrop appears on nearly every map of the area.

The plateau is reached from Ochsenwang via Kreisstraße 1220, which runs directly past the rock; the distance to Bissingen an der Teck is about 5 kilometres. The roughly 200-metre-wide plateau edge drops steeply to the north, so keep back from the rim. A bronze plaque on the plateau shows the location and distance of the visible places.

The plateau is about 200 metres wide and made of White Jurassic rock, and a bronze plaque on it lists the places visible from the edge and their distances. The view reaches roughly 400 metres down to the land north of the Swabian Jura and as far as Stuttgart in the north-west. The rock face and cave are protected as a geotope and as an areal natural monument.
