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

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

The Jägerwegli with its rock formations is very impressive. But you definitely need good shoes. With smaller children you should be careful because it sometimes goes steeply downhill on the other side. In no case will it be boring on this hike :)
