Teckberg, Mountain summit in Baden-Württemberg, Germany.

Teckberg is a 775 m high mountain in the Swabian Jura, crowned by Teck Castle. Its slope is marked by the Yellow Rock, a bright limestone sponge reef from the Jura Sea, and beneath it lies the 31 m long Veronikahöhle. The mountain is a nature reserve of 386 hectares, home to 464 plant species.

Three burial mounds on the eastern slopes of Teckberg show that people lived in this area during prehistoric times. Excavations carried out in 1898 at the Sibyllenloch cave uncovered animal bones from the glacial period.

East of the Yellow Rock, three burial mounds from the Hallstatt period (800–400 BC) mark early settlement on the Teckberg. The mounds lie on the eastern slope, above the Sibyllenloch cave, where excavations in 1898/99 uncovered over 2,000 skeletal remains of cave bear, cave lion, cave hyena and wild horse.

The summit can be reached by marked walking trails that pass through different types of terrain. A visit in the warmer months makes it easier to enjoy the paths through wet meadows and forest edges.

A bright limestone rock formation at the top known as the Yellow Rock is a visible remnant of an ancient reef from the time when the Jura Sea covered this region. Walking past it gives a direct sense of how different this landscape once looked.
