Aargau Jura Park

Aargau Jura Park (Jurapark Aargau) is located north of Aarau, between the rivers Aare and Rhine, in the Swiss canton of Aargau. It straddles the border between Jura and Basel. It spans 241 km2 and reaches up to 350 m above the valley floor. The park is mainly located on the Jurassic Plateau, between Frick and Villigen, and also encompasses the Aargau Jura mountains and valleys. The northern area includes sparse pine forests, fruit orchards, rocky steppes, dry meadows and terraced vineyards, while the southern region fosters forests and wildlife. It was declared a regional nature park of national importance in 2012 by the Federal Office for the Environment.

The villages Herznach and Wölfinswil traditionally mined ore in the park and thus, left many studs. A mining tunnel was excavated and made accessible to visitors.
