Piz Corbet

From Campodolcino a narrow road climbs to Starleggia (1,565 m); cars can continue about 70 m higher to a barrier where a driving ban begins (about 1,640 m). There is no public transport above Campodolcino. Walk past Alpe Bocci and the old stone huts of Morone, then on a mountain path through open forest into the Valle della Sancia to a small weir at 2,010 m. Follow a concrete water channel on the level, then a steep path to a broad shoulder leading towards Motto Alto (2,720 m); the path is waymarked red and white and reaches the Bivacco del Servizio (about 2,590 m), below Motto Alto on its south-east side, in a little over 3 hours. From the bivouac, follow the red-and-white path briefly towards Pizzo Quadro, then descend over scree and broken ground to cross a stream at about 2,536 m. A grassy rib, easy to walk and bounded by a rock wall on its south side, leads to about 2,700 m. From there a mostly easy scree slope, with blue-and-white marks on a ramp at the end, leads to the Bocchetta del Sevino (2,916 m). Just before the col a sign separates a 'via facile', which goes over to the Italian side and passes about 300 m below the summit towards the Bocchetta del Pombi, from the summit route ('via difficile'). The marked route first traverses the west (Swiss) flank below the ridge, losing a little height, then gains the north ridge for easy blocky scrambling (I) to the summit. Climbing the lower ridge directly is harder (WS/T5, II). Descend the same way. In fog the scree between the bivouac and the col is hard to navigate. Allow about 2 hours from the bivouac back to the car.
