From the village of Usseglio, follow the GTA markings briefly before leaving them at the edge of town to join the Percorsi Sindonici (PS) itinerary. Pass through the hamlet of Pianetto and traverse the entire plateau along its orographic left bank.

Just before reaching the hamlet of Piazzette, leave the PS trail to the right and continue leftward (marked 131 TC, Tour del Calcante), gaining about 200 meters in elevation. Passing below the slopes of Monte Tumolera, you reach the hamlet of Ciampermà and eventually enter the Vallone d’Ovarda at the village of Villaretti (1,149 m). From here, descend towards Lemie, making sure to take a short detour to admire the beautiful Ovarda waterfall.

From Lemie, descend towards the Stura river and cross to its orographic right bank. Follow the PS markings as a reference towards Forno di Lemie and Viù. Continue descending until you reach the village of Villa, followed closely by Forno di Lemie, home to the striking Chapel of San Giulio and a historic medieval bridge.

After crossing the Forno bridge, climb through a lush forest on the orographic left slope towards the hamlet of Pessinea. From here, an enjoyable and largely level path leads to the village of Balma and the characteristic settlement of Tornetti. Finally, follow the trail flanking the Rio della Viana for a long descent that brings you into the heart of Viù.
