It visits a number of fascinating historic sites, including the spectacular ruins of the tilt hammer and furnace in Carena, mines shrouded in mystery and the reconstruction of a charcoal pile. The path winds its way through the evocative Alpine environment of the Alpe Giumello, crossing through a rare dwarf mountain pine wood to the Giggio forest.
The route departs from Piazza Via del Ferro in Carena, home to a commemorative statue and the first information boards. It visits all the points of interest associated with mining and working iron that developed in the upper valley during the second half of the 15th century and between the 18th and 19th centuries. It is therefore possible to visit the ruins of the Maglio e Forno (tilt hammer and furnace) in Carena, brought to light after almost two centuries of abandonment, the two mines in the Valletta rediscovered in 2005 (the inside of the mines may only be visited as part of a guided tour) and the reconstruction of a charcoal pile.
