Sandgrube im Jagen 86 des Grunewaldes

Sandgrube im Jagen 86 is a protected nature reserve in Berlin featuring deep sand excavations and diverse habitats. The site combines open water surfaces, willow thickets, and steep sandy slopes into an ecologically varied landscape.

From 1966 to 1983, the site operated as an open-pit quarry supplying sand for Berlin's construction industry. Following closure, the former industrial ground gradually developed into a valuable biotope with distinct ecosystems.

The place has become an important site for environmental education and nature conservation in the urban area. Visitors can observe how different habitats interact along the paths and understand how nature recovers after human use.

The site offers multiple access points with paved paths accommodating different mobility needs. Visitors should know that some sections have steep inclines and sturdy footwear is advisable.

The reserve harbors a specialized community of ground-nesting bees and wasps in designated protection zones. These insects are visibly active to visitors and demonstrate a fascinating form of coexistence with human leisure use.
