Starting from Romainmôtier, the Iron Furnace Trail is an easy walk which is accessible all year round. It takes walkers through a beautiful oak tree forest to an archaeological site with two iron furnaces probably dating from the 6th century. These furnaces, used in the olden days to reduce iron ore, are a unique testament to the region’s activities and the role played by Romainmôtier at the beginning of the Middle Ages.
Just over 7 km long, the walk takes about 2 ¼ hours. Although the path is quite flat, sturdy walking shoes are advised.
