Fröruper Berge, Nature reserve in Oeversee, Germany

Fröruper Berge is a nature reserve in Schleswig-Holstein featuring diverse landscapes including rewetted moors, heathlands, and forested hills shaped by the last ice age. Marked hiking paths wind through varied terrains, connecting moorlands, beech forests, and terminal moraine formations across the area.

The Fröruper Berge became a nature reserve in 1936. Gravel and stone were extracted from part of the area in the first half of the 20th century; around 1920 the pit was the largest gravel works in northern Schleswig-Holstein. The material was used for North Sea coastal protection and for building the Hindenburg Dam, transported by a narrow-gauge railway. Extraction continued in places until the 1960s, and reforestation began around 1950.

School groups regularly visit to explore the landscape and discover rare orchids and insects while learning about local ecosystems. These visits help people understand how nature recovers in rewetted areas and woodland habitats.

The area is easy to explore with an extensive network of marked trails offering multiple entry points and varying difficulty levels. Wear sturdy hiking shoes to handle different ground conditions, from dry forest paths to damp moorland sections.

Frørup Skov, the woodland within the reserve, is first recorded in 1604, while the Budschimoor bog and scrub is documented from 1748 and Hjorthøj Mose from 1806. The name Budschimoor may derive from Jutlandic "bus" for withered grass, and Hjorthøj from the Danish word for deer.
