Via Alpina leaves Castérino and passes near the old Peïrefique barracks and then the Giaure fort established on the border with Italy. From the ridge a trail leads down over scree slopes and through woods to the valley of the Prati della Chiesa stream. It then meets the road, which quickly leads to Limonetto. This leg is practicable by mountain bike, too from Castérino to Limonetto (through Baisse de Peyrefique and Colle di Tenda).
Leave the hamlet of Castérino and follow the road to the south for 400 metres, leaving it to cross the Valmasque river on the bridge to the left (marked in yellow, marker 367). Follow the track that climbs to the north east into the forest until reaching a track junction (marker 369). Take the track that climbs northward for 250 metres to arrive at the Peïrefique pass (marker 370) and then continue on this track, which takes a level course for around 750 metres, then descending slightly and passing in front of the abandoned Peïrefique barracks. A few metres further, take the path that climbs to the west (yellow markings) and leads to a grassy slope on the Barchenzane crest (marker 378). Descend on the northern side along the rocky slopes to reach marker 379 lower down. Leave the path to the left that leads to the Peïrefique lakes (worth seeing, 20min) and head towards the north east and then the east on the trail that crosses a scree-covered area below the ledges of the Abysse rock and then climbs to a little plateau on which the Giaure fort stands (2,254m, marker 380). From the fort, take the beautiful track that heads down on the north side and leads to the border with Italy.
(Paul Guglielmi, CDRP 06)
On the hillsides of the Roya valley, the wooded route rich in flora crosses over to Italy and the Tende community, a disputed area for long periods of time. The current configuration of this community is one inherited from history, when it was the subject of many difficult diplomatic episodes.
