Kobersfelsen, Protected area in Burgk, Germany.

Kobersfelsen is a grey-brown slate rock face rising steeply from the Burgkhammer reservoir, its uneven surface dotted with small trees and shrubs. At its base a narrow walkway on thin posts runs along the waterline, about 3 m above the water. The 6 ha nature reserve protects silicate rock and slope woodland with crevice vegetation.

The area became a protected nature reserve in September 1989 following a decision by the Gera District Council in Thuringia. This designation safeguarded the region's distinctive natural features for the future.

The rock's name stems from a local legend about Elisabeth, daughter of the Lord of Burgk, and her love for Knight Kober. This story shapes how people in the area speak about and remember the place.

A hiking trail along the Saale, part of the Eisenach–Budapest long-distance route (European E3), leads to the rock. The roughly 150 m hanging walkway fixed to the rock about 3 m above the water has been closed since a rockfall in 2021; repairs and protective nets are planned, but reopening was not expected in 2024.

The hanging walkway fixed to the rock, about 150 m long and roughly 3 m above the water, has been closed since a rockfall in 2021; repair plans and protective nets anchored in the rock exist, but reopening was not expected in 2024. The name is documented in the 19th century, so it cannot come from the author Julius Kober.
