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.

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.
