Tunnels, caves, single trails... A completely surprising and surreal area so close to the city of Zurich. The paths here are narrow and are often used for walking and hiking. Be considerate, be friendly and push your bike a bit. That way you can enjoy the Sihlsprung - and so can the others. Thank you!

A worthwhile detour, especially with children. The path is still officially closed, but only a few people follow the detour. The "massive landslide" now looks quite tidy, and the cave is easy to enter.
