Erpetal, Nature reserve in Hoppegarten, Germany

Erpetal is a 183.6-hectare nature reserve (protected area no. 1531) on the territory of Hoppegarten in Märkisch-Oderland, Brandenburg. It lies east of the Waldesruh district and follows the Erpe, a right tributary of the Spree. The B 1 runs along its northern edge, and the Berlin state border touches its southeastern edge.

The area received protection in 2003 to preserve local ecosystems and wildlife habitats. This decision was part of a broader initiative to protect natural wetlands and forest areas in the region.

The area is known among nature watchers and walkers who come to observe native plants and wildlife. The open meadows and woodland edges display typical landscapes of the Brandenburg region.

The site is easily accessible on foot, and the marked routes allow safe navigation through all sections of the protected area. Sturdy footwear is recommended, especially after rain or in wetter sections.

The reserve lies directly on Berlin's southeastern border: its southeastern edge follows the state boundary, while the B 1 runs along the northern rim. The Erpe, a right tributary of the Spree, flows through the area east of Waldesruh, the Hoppegarten district it is named after.
