Meisterstein, Natural monument and summit in Hochsauerlandkreis, Germany.

Meisterstein is a summit in the Hochsauerlandkreis region standing at around 636 meters high. Steep rock walls surround a lake that formed in a former quarry site.

Quarrying was particularly active in the 1930s when diabase was extracted from the mountain. The excavation later filled with groundwater to form the lake that exists today.

The site is part of the GrenzWelten Geopark and displays the rocks and geological story of the region. Visitors can discover different stone types and learn how this landscape was shaped through educational paths.

The path to the lake is called Stollenweg and begins in Silbach village center. The cliff areas around the summit are unsecured, so visitors should move carefully and stay aware of steep edges.

On 22 June 1915 the quarry was the site of the first confirmed peregrine falcon breeding in Westphalia, when Koch found three young birds there; at the time only the Bruchhauser Steine was also known as a peregrine nesting place in the region. Today a Eurasian eagle-owl breeds in the quarry, and climbing is banned in its breeding area from 1 February to 31 July.
