Hummelsberg

Hummelsberg is a summit in Denkingen standing at 413 meters high, known for its hiking and mountain biking routes that cross its slopes. From the top you can see across the countryside toward Rottweil and the surrounding region.

The mountain formed around 25 million years ago from volcanic activity and displays characteristic hexagonal basalt columns across its surface. Basalt quarrying shaped the slopes for much of the modern era before operations eventually stopped.

Today the summit serves as a popular gathering point for outdoor enthusiasts who come to explore the surrounding trails and enjoy the expansive views. Locals and visitors use it as a natural landmark for navigation and outdoor recreation in the region.

The summit is accessible by hiking and mountain biking trails that depart from several nearby towns in the region. Visitors should wear sturdy footwear and bring water, as the routes can take several hours depending on the path chosen.

Where a basalt quarry once operated, a water-filled lake now marks the spot after extraction work stopped in 1984. This unexpected transformation shows how abandoned industrial sites can naturally reclaim themselves and become part of the natural landscape.
