Medium-difficulty itinerary, peculiar for its landscape. Starting point in the little hamlet of Toffol, where ancient rural houses fascinate the viewer with their beauty or you can start also near the ski cross country tracks 100. Follow the road and then the valley which leads to the alpine pastures of Mondeval, where the remains of a prehistoric hunter were found. Then the path turns left, towards North-West, leading to the wide snow-covered basin of Mondeval di Sopra. Go past the Mondeval de Sora farmhouse where you can stop to eat something, and then head North-West to reach the enchanting Lago de le Baste. Here the track turns left (Southbound) following a short ridge which leads to the Corvo Alto top. To come back follow the same itinerary.
