Thal Nature Park
Thal Nature Park is located in the Canton of Solothurn and encompasses the broad high valley of the Dünnern River, tucked away between the chains of the Solothurn Jura. Spanning approximately 139 square kilometers, it was officially recognized as a regional nature park of national importance in 2009. The landscape is characterized by prominent limestone cliffs, extensive beech forests, and fertile valley floors. Historically significant are the numerous castle ruins, such as Neu-Falkenstein and Alt-Bechburg, perched on strategic ridges overlooking the valley. The park fosters a combination of sustainable agriculture, soft tourism, and biodiversity conservation. Hikers value the dense network of trails leading across the Jura heights, offering expansive views stretching as far as the Alps. A unique project within the park is the preservation of the historical iron industry tradition that shaped the region for centuries. The visitor center in Balsthal provides insights into the geological features and cultural richness of the valley.
