ホルゲンの天然記念物・トップ16

南に隣接するGrindelrietがあるBergweiher池は、人気のローカルレクリエーションエリアであり、湿地の植物や動物にとって貴重な生息地です。ビーバーもそこに定住し、巣を建てました。そのため、池の南部と湿地帯は保護されています。北側では水浴びが可能で、ピクニック/バーベキュースペースのためにレクリエーションゾーンが設けられています。

A beautifully landscaped and well-maintained wilderness park (no entrance fee), with many animals - including predators (bears, lynxes, wolves).

From the north, a relatively easy, clearly visible, unmarked path leads to the plateau on which Schnabelburg Castle stands. The descent to the south is very steep and, when the ground is wet and/or covered in autumn leaves, also very slippery.

This section of the Sihl River is truly breathtaking. Crystal-clear water flows gracefully around massive boulders that rise majestically from the riverbed. The sound of the water cascading over the stones adds a soothing rhythm to the natural symphony of the landscape.

The Albis chain is a striking, largely forested mountain ridge that runs parallel to the Sihl and Lake Zurich from Sihlbrugg to Urdorf / Schlieren. It is flanked by two valleys, the Sihl valley in the east and the Reppisch valley in the west. The eastern flank of the Albis is steep, characterized by ridges, deep ditches and numerous streams. It is geomorphologically extremely active, sparsely populated and largely covered by the Sihl forest. The western side is less steep and has an unusually strong interweaving of forest and grassland on steep slopes for the Central Plateau. Here, the interaction between site conditions and human use has led to diverse, sometimes rare habitats.

The Sihlwald is the first protected area in Switzerland to be awarded and certified as a national park with the label "Nature Adventure Park". Since 2000, the Sihlwald has been left to itself, natural processes run undisturbed. A wilderness is emerging. There is a lot of dead wood in the natural forest reserve, as fallen trees are left lying and left to their natural dynamics.

The Schnabelburg is the ruins of a hilltop castle on the beak-shaped hill north of the Schnabellücke above the village of Hausen am Albis in the canton of Zurich. Source: Wikipedia
