The Hohenbol is a 602.1 m above sea level (NHN)[1] high mountain 2 kilometers from the town of Owen in the district of Esslingen in Baden-Württemberg.

The Teckberg and the summit of Hohenbol (above the orchard slope) are a nature reserve protected area.

It is originated in the Miocene, when one of the volcanic vents of the Swabian volcano forced its way through the surrounding rock.

Through erosion of Hohenbol was (especially in the west and north) exposed the softer surrounding material.
