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.

A hike through the Chaltbrunnen Valley offers a fascinating mix of nature and history. A highlight of the hike is the Wappenfelsen right at the beginning, a memorial to the troops that were stationed here during the First World War. Their job was to guard the two railway bridges and, in an emergency, to blow them up if German troops tried to use them.
