Hacken and Rottauer Filz are closely linked, as they are both part of the fascinating cultural landscape in Chiemgau (Bavaria). While one is a picturesque village, the other is one of the most important nature reserves in the region.

Hacken am Chiemsee is a picturesque district of the municipality of Bernau, known primarily for its idyllic location in the Achen delta. The interplay of ford and bridge is a central feature of the landscape design and flood protection here. In Hacken lies one of the region's most famous fords. This is a shallow spot in the river's course (the Tiroler Ache), traditionally reinforced so that it can be crossed by vehicles or hikers.
