Dolinenweg Hengen
Useful Information
History
Description
The Dolinenweg Hengen (doline trail Hengen) is a 8km long trail, which leads to several interesting
Karst features.
The main topic are, of course, the six dolines along the path, which are protected.
Beneath their geological interest, they are important biotopes in the waterless karst landscape.
Of special interest are the Au-Löcher.
One of them contains a well that flows all the year.
It is produced by the water resistant volcanic tuff from the Hengen volcano.
The water forms a brook, which enters the karst nearby in the second doline flowing into a sinkhole.
The sights of the trail are described on big signs, located nearby.
