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.

Already 12,000 years ago, gatherers and hunters used the protection of the caves in Chessiloch.

Great gorge just outside Basel with a lovely fireplace. In midsummer, when the temperatures in the city are hot, this detour into the cool gorge is particularly worthwhile. Very interesting for children, as it is only a 10-minute walk from the car park.

The rocks of the Grotte des Nains form an impressive gorge, approximately 25 meters high. According to legend, the little women of the earth lived here with the Erdmanala (little men of the earth). The gorge gives access to the Plateau des Nains and a beautiful view of the Ill valley.

It is said that the gorges near Ferrette were inhabited a long time ago. Dwarves lived there and lived in the hollows. These friendly creatures had eternal youth and beautiful childlike faces with shining eyes. Their small cave houses were decorated with all kinds of silver objects. To the left of the Grotto of Nains, where the Smurfs live, there is a crack in the rock, here you can climb up to the plateau and enjoy the beautiful view.

According to legend, this cave was inhabited by a tribe of dwarves. These dwarves, in Alsatian Erdwibala and Erdmanala, were of great beauty and enjoyed eternal youth. They were very kind and helped the surrounding peasants in their work, however always wearing long robes that hid their feet. Some young girls from the valley decided to unravel this mystery and hid near the cave, after having covered the stones at the entrance to the cave with fine sand. When the dwarves came out of the cave, the girls saw their footprints in the shape of goat's feet and burst out laughing. The dwarves were very upset, retreated into the cave and were never seen again...
