Herznach mine

Herznach mine

Iron ore was mined for centuries in the Upper Frick Valley. An adventure trail with 10 stops that begins in Wölflinswil highlights this history. In Herznach you reach the real centre of the iron trail, the old mine, where – subject to advance booking – you can ride the gallery railway to the entrance of the former main tunnel, view a wonderful collection including fossils from the mine, and enjoy a convivial drink in the disused mine silo.
