We walk mainly along an old route of the Ferrovie Meridionali Sarde (FMS), now almost entirely transformed into a pedestrian and bicycle path, which for about half a century (from the early ’20s to the early ’70s of the last century) ensured the mobility of people in this area, as well as the transportation of coal from the Great Mine of Serbariu to the port of Sant’Antioco. It is one of the longest stages of the Cammino, but it is very easy and without particular difficulties.
