From the locality of S. Antonio, leaving the SS 52 Bis, follow the main paved road uphill, taking a left shortly after (local signs).
After crossing a small bridge, you reach a final building before a very steep section where you must follow a narrow paved road leading to a rustic building in the woods. From here starts trail 212, which climbs the entire wooded slope passing near the Clapì barn (a wide grassy area) and ascending, always quite steeply, the edge of the scree below Mount Rancoli. After climbing the last wooded shoulder, you reach the meadows of Casera Costa Baton.
After passing the building, keep the left track through the meadows towards the Rancolin saddle, which can be reached without possibility of error.
At the saddle, continue on the watershed for about fifty meters, then take a track that descends to the right among the scree and, passing a steep green section, reconnects with trail CAI 213.
Following the trail, you reach the forest road which, with wide switchbacks and gentle slopes, leads back down.
Near the large meadows of Chiampì, turning right will bring you back onto the paved road to the starting point, closing the splendid loop.
