Sihlwald · A Quiet Wilderness

Cherish Nature

Where the Forest Is Allowed to Be

The Sihlwald and the surrounding Sihl Valley are among the natural landscapes that have stayed closest to my heart. Perhaps living nearby makes the connection even more personal, but its fascination reaches far beyond familiarity.

What makes this forest extraordinary is the freedom given back to nature. Instead of constantly shaping and controlling it, large areas are allowed to develop according to their own rhythm.

Every visit is different. Light, weather, vegetation and water continuously transform the landscape. A path that feels familiar in summer can become an entirely different place in autumn fog or beneath winter snow.

Natural Forest

A Forest Returning to Wilderness

The Sihlwald forms part of the Wildnispark Zürich and represents one of the most important large-scale beech forests on the Swiss Plateau. Its landscape is characterised by trees of many different ages, fallen trunks, regenerating woodland and steadily increasing amounts of deadwood.

This deadwood is not lifeless. It provides an essential habitat for countless fungi, plants, insects and other organisms and is one of the foundations of a naturally functioning forest ecosystem.

Old trees, young growth and decaying trunks exist side by side, creating the constantly changing mosaic that gives the Sihlwald its particular character.

A Protected Landscape

Since 2010, the Sihlwald has carried the national designation of a Nature Discovery Park of national importance. Its core areas are designed to give natural processes as much space as possible, while surrounding zones allow people to experience the landscape responsibly.

Flora & Fauna

Life Between Old Trees

Where a forest is permitted to grow old, fall and renew itself, an extraordinary variety of habitats emerges.

Wild garlic covers parts of the forest floor in spring. Mosses, fungi and countless small organisms inhabit fallen trunks, while wetlands and ponds create habitats for amphibians and water birds. The result is a landscape that never truly stands still.

Near the beginning of the Sihlwald lies a quiet pond that changes dramatically with the seasons. During summer, water lilies and reeds transform its surface while birds move through the surrounding vegetation.

The Sihl

The River Through the Valley

The forest cannot be separated from the river that gives the valley its name. The Sihl begins in the mountains of Central Switzerland, flows through the Sihlsee and continues north through the valley before eventually reaching Zurich.

Its changing water level, stones, banks and surrounding vegetation form another constantly evolving part of the Sihlwald landscape. After periods of heavy rain or snowmelt, the quiet river can become unexpectedly powerful.
