The Glögglifels is a striking rock formation above Laufen (BL) in the Jura Mountains. It lies on the hiking trail towards the Blauenpass and offers a beautiful view into the Birs Valley. The name likely derives from its bell-like shape or a former bell-ringing site.

The Glögglifels is a striking rock formation above Zwingen in the Laufental valley. It offers a beautiful view over the Birstal valley and is a popular viewpoint for short hikes. Legends and the name itself lend the place a mystical character.

In addition to its scenic beauty, the Kaltbrunnental Valley is a great outdoor playground for families. The stream offers fun activities and children's canyoning, easy access to the water, and barbecue areas are available. A hot tip, especially in summer.
