The S21 line leads through charming landscapes and connects the Solothurn and Bernese Jura regions with the almost four-kilometre long Weissensteintunnel. It also opens up the Thal Nature Park. A trip with the tunnel cinema, a visit to the Sikypark, a guided tour of the forge workshop or a visit to the Jura Art Museum - the region has fascinating experiences to offer.
