A four-day hiking itinerary for the Tour du mont Viso, covering 51 kilometers, weaves through shelters, lakes, and rugged mountain passes between the French region of Queyras and the Italian region of Piemont. This route is popular among hikers seeking a challenging yet scenic journey through the Alps. The trek starts in La Roche Écroulée, a village surrounded by larch trees, and climbs through the Guil valley to the Viso refuge after the first 8 kilometers and a climb of 700 meters. From this point, hikers can enjoy views of Mont Viso, a mountain that rises to 3,841 meters and straddles the French-Italian border. The second stage takes hikers from the alpine meadows into a more rocky and mineral-rich landscape, with an ascent to the Traversette pass and its historic tunnel, which dates back to the 15th century. After crossing into Italy, the trail continues to the Chiaretto lake, where hikers traverse scree—loose rock fragments—before reaching the Quintino Sella refuge, located beneath the eastern face of Mont Viso. This stage spans 14 kilometers, involves about 6 hours and 30 minutes of walking, and includes a climb of 1,200 meters and a descent of 1,000 meters. The third stage of 14 kilometers begins near the lake that borders the refuge, starting in a wild and mineral-rich environment. The path ascends toward the south to the Passo Gallarino, then continues on a high ridge toward the Passo San Chiaffredo. After descending into the Giargiatte valley, hikers climb through the green alpine meadows of the Vallante valley to reach the Vallante refuge. This stage takes about 6 hours, with a climb of 670 meters and a descent of 850 meters. The final stage leads to the Vallante pass, where hikers can enjoy sweeping views of the Queyras region. The descent follows a trail of rocks and stones on the northern side before reaching the gentler alpine pastures around Lestio lake, ultimately returning to the starting point. This last stage is 15 kilometers long, with a walking time of about 5 hours, and includes a climb of 400 meters and a descent of 1,040 meters.
