Aargau Jura Park

Aargau Jura Park (Jurapark Aargau) is a regional nature park of national importance in the Swiss canton of Aargau, north of the city of Aarau. It lies between the rivers Aare and Rhine and was recognised as a regional nature park in 2012 by the Federal Office for the Environment. Its member municipalities include Frick, Herznach-Ueken and Wegenstetten.

What is the landscape like?

The park covers the Aargau Jura: gentle hills, valleys and a Jurassic plateau stretching roughly from Frick to Villigen. The northern area features sparse pine forests, orchards, rocky steppes, dry meadows and terraced vineyards. The south is more wooded and home to a good deal of wildlife. This patchwork of habitats means the scenery changes noticeably over short distances, which suits day trips well.

What can you see around Herznach-Ueken?

Herznach has a long history of iron-ore mining. The former mine can now be visited and has its own exhibition explaining how mining shaped local life. It is one of the park's more interesting historical stops.

Around Frick, cherry trees are a signature feature of the landscape, especially striking in blossom season. The Cheisacher lookout tower offers views across the surrounding hills and valleys.

How can you explore the park on foot?

The Aargauer Weg, a trail of about 105 km, crosses the park. It links the Fricktal valley with other parts of the canton and passes a water castle, Wildegg Castle and Königsfelden Monastery. You can walk it in sections to match your fitness.

Shorter themed routes exist too. One suggestion starts in Wittnau, runs through Frick, Ueken and Herznach and finishes near Aarau. It is around 37 km with nearly 700 m of climbing, so it suits keen hikers or cyclists.

Is it a good place for families?

Yes. In Wölflinswil, Herznach and Biberstein, Perimuk trails let children find waypoints using photo cards, turning a walk into a simple outdoor game.
