Climbing on the Stenzelberg has been expressly forbidden since June 2005. Previously, the Rhein-Sieg district had tolerated climbing, although the Stenzelberg, like the entire Siebengebirge, had been designated as a nature reserve (NSG) since 1920. The climbing ban became necessary due to the new nature reserve ordinance in the course of the recognition of the Siebengebirge as FFH area 5309-301 (Fauna-Flora-Habitat) of the European Union. In particular, the occurrence of the wall lizard was concerned and egg-laying sites at the foothills of the fields were destroyed. Despite the ban, climbing continued illegally after 2005. The path to the rocks was therefore closed by the forestry department.

The Stenzelberg is geologically a spring dome from the volcanic rock Latit. The rising magma did not reach the earth's surface here, but got stuck in the surrounding tuff cover rock. The softer tuff was later eroded away, exposing the harder latite. The Stenzelberg has been used as a quarry since the 11th century, in which quartz latite rock was mined. The Heisterbach Abbey also operated a quarry on the Stenzelberg. The quarried material was also used to build the monastery buildings and the abbey church. Furthermore, rock from the Stenzelberg was used for the Propsteikirche in Oberpleis, the Nikolauskapelle in Heisterbacherrott and the Bonn Minster, and later also for the churches in Niederdollendorf, in Oberdollendorf and in Asbach. The operation of the quarry ended in 1931. Source: https://www.kuladig.de/Objectansicht/O-FJK-20100630-0032

The Stenzelberg has retained its attractiveness even after stone quarrying ended. Stones have not been quarried since 1931. Due to its picturesque rocky landscape, the Stenzelberg is still a popular destination for many hikes. In addition, the 287-meter-high summit offers habitat for animals such as smooth snakes and wall lizards. For this reason, it is kept free of shrub and tree growth.

The Stenzelberg is a 287 meter high mountain in the Siebengebirge and is located southwest of the Heisterbacherrott district of Königswinter near the Heisterbach monastery. Geologically, the Stenzelberg is a spring dome from the volcanic rock Latit, whereby the rising magma did not reach the earth's surface, but got stuck in the surrounding tuff cover rock. Erosion later eroded the softer tuff and exposed the harder latite. The Stenzelberg has been used as a quarry for quartz latite since the 11th century. The stone was used, among other things, for the Propsteikirche in Oberpleis, the Nikolauskapelle in Heisterbacherrott and the Bonn Minster, and later also for the churches in Niederdollendorf, Oberdollendorf and Asbach. Quarrying ended in 1931.[3] After the closure of the quarries, a characteristic landscape developed on the Stenzelberg, which offers the special flora and fauna of a dry biotope.
