Worth seeing. And, as with most caves, it is advisable to take a jacket with you :-)

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!

Road to seebodenalp closed until autumn. Various routes are subject to a general driving ban. Trail down to Oberarth is cool but only if there are few hikers!
