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 Hutzmetreppe in the Falkenflue connects Hochwald and Duggingen. The approach from above is much more pleasant than from below, as it is really steep here! It is also worth taking a look under the rocks of the stairs, where you will find a water source that comes directly out of the rock.

Fabulously beautiful place. The narrow part of the gorge could have come from an adventure novel. :)

The Hutzme Staircase connects the communities of Hochwald and Duggingen via the 'Falkenfluh' area. There are some caves and a spring under the stairs.
