Embark on the Monte Granero and Monte Meidassa loop in Valle Po for a truly demanding high-alpine hike. This difficult route spans 8.2 miles (13.2 km) with a significant elevation gain of 4025 feet (1227 metres), typically taking around 7 hours and 14 minutes to complete. You will navigate varied terrain, including mountain and alpine paths, some unpaved or gravel, with sections requiring careful navigation over loose scree and even grade II climbing on the final push to Monte Granero. From Monte Meidassa, you can enjoy expansive views of the majestic Monviso massif, often called the "the King," and on clear days, even distant peaks like the Matterhorn and Monte Rosa.
To tackle this challenging loop, you need a very good level of fitness, sure-footedness, sturdy mountain shoes, and alpine experience. Parts of the route involve technical or hazardous terrain, and specialist equipment may be required for safety. The final ascent to Monte Granero demands maximum caution due to its technical nature. This trail offers a genuine high-alpine experience, traversing altitudes above 3,000 meters, so be prepared for conditions typical of such elevations.
One of the most unique features of this trail is the historic Buco di Viso, or Tunnel de la Traversette. This 75-meter long tunnel, carved into the rock at 2,882 meters, was completed in 1480, making it the first Alpine tunnel. Commissioned by Ludovico II, Marquis of Saluzzo, it was a marvel of civil and alpine engineering designed to facilitate trade. The loop also offers continuous views of the iconic Monviso Massif and passes through Pian Mait, a crucial viewpoint and crossing point for the famous Giro del Monviso.
