This stage is interesting from a historical and environmental perspective, as it takes in one of the most atmospheric areas of the Waldensian Valleys. The route passes through a number of sites of significant historical interest. In addition, it is linked to events that took place during the period of The Italian Resistance: The Tempio di Pradeltorno, the remains of Collegio dei Barba (used probably for religious training), and the ruins of the ancient dwellings of Barma Monastira and Barma dl'Ours (Barma being an ancient shelter or dwelling usually built into the rock).
From the Alpe Vandalino descend towards Sea di Torre, and follow signs for “Agriturismo Barfè”, trail marker 140A, to reach Prato Stella (1294m). Then take path 140. The trail continues across flat alpine pastures above the treeline overlooking Val d'Angrogna, passing a number of " cumbals " (undulations caused by runoff streams) and some foresti (tracts of abandoned wood): Cialaroccia (1336m) and Sapè (1390m) to reach Embergeria (1381m), a small, still active mountain pasture, and intersection with path 138A which leads to Rifugio “Al Sap” in about 20 min.
From Embergeria head down into the woods passing by the small hamlet of Ramà and the locality of Palai, theatre of events linked to the persecution of the Waldensians and the Italian Resistance, to reach the Lausa bridge (970m) which crosses the Angrogna stream. From here, follow the road along the valley bottom until you reach the town of Pradeltorno (1000m), a refuge of last resort during the period of the Waldensian persecutions from the 15th century to the 17th century. Continue on to the Tempio Valdese built in 1876 and the "Collegio dei Barba", where a traditional sixteenth century "schola" (school) has been reconstructed, in which itinerant Waldensian preachers (called "barbi” in local dialect) sought refuge in order to study theological texts in secret. Continuing on, you reach the forest track, Trail 141, which passes through the hamlet of Fau, set against a huge rock. Continue along a path that passes the farm settlement Turle (1150m), to reach a rock from which you can enjoy a beautiful view and which leads rapidly to the houses of Barma Monastira, built in the shelter of a large rock. The path enters the woods and reaches the ancient dwelling known as Barma dl'Ours (1183m), which in 1944 was used by partisan groups belonging to the resistance movement Giustizia e Libertà (Justice and Liberty) as a clandestine printing office. From here follow the signs for sentieri partigiani (Partisans’ trails) towards Bagnau until you reach the "Ca d'la Pais" (1422m), a structure that was bombed in January 1944 by the Nazi-Fascists during an operation to combat partisan activities. Forty years later, it was rebuilt by the Waldensian community of Angrogna to transform it into a meeting place, dedicated to peace and reconciliation among peoples. From here a dirt road, signposted 150 A, leads shortly to Colle della Vaccera (1465m).
