The hike starts at the Mont Cinto campsites in Lozzi.
(S/E) Follow the dirt track that runs alongside the campsites until you reach the wooden sign indicating "Refuge de l'Erco". Then follow the path, cairns and other signs. The path is well marked, cuts across the land and crosses the dirt road several times.
Continue to the Petra Pinzutta sheepfolds.
(1) Leave the path leading to the Bergeries de Cesta on your right and turn left towards Refuge de l'Erco.
(2) At the refuge, follow the path heading north. It is well marked and there are numerous cairns.
The path becomes less clear towards the summit. You will need to follow the cairns, which are once again numerous, to reach the summit. White markings also indicate the path to follow. The summit can be reached without too much difficulty and it is hard to get lost.
(3) For the descent, head southwest, following the red markings and cairns. The trail follows the ridge. In the fog, we lost the path that descends to Lake Cinto, but the large scree slope that leads there can be descended without difficulty (several trails have been carved out).
(4) Once you reach the lake, the cairns and the trail are clearly visible all the way to the Erco refuge.
(2) Follow the same path as on the way up to return to the starting point (S/E).
