The outpost for the climb to the Corno Bianco
From Alagna follow the path to Otro and reach alpe Pian Misura (2 h) After the last houses of the small hamlet on your left side you follow direction Kultiri, a small pasture with only one house at m 2113. Few metres before the house you see, well marked, the detour for Granus and Bivacco Ravelli. In 45 minuti you reach the 2250 m of a glacial basin where path n 203D-3D goes to Granus m 2338 and Passo della Coppa m 2916 and path 203 goes to Terrafrancia lake and the Ravelli bivuac m 2504 (h 2-3.30).
From the bivouac pass the Alta Via Tullio Vidoni, path for hikers, that gives way to surround the Corno Bianco in three stages.
The Ravelli Bivouac was built on the initiative of the CAI section of Varallo , in the area called Laghetto Terrafrancia in Val d’Otro in 1964 to commemorate the figure of Don Luigi Ravelli. He was a priest, mountaineer, author of a well-known guide and Alpine historian of the Sesia Valley . Earlier the same section of CAI had already expressed the desire to build a foothold in Val d’ Otro for easier access to the summit of Corno Bianco .
The Ravelli bivouac (unguarded and open all year) has 12 bunks with mattresses and blankets, gas stove , pots and a first aid cabinet. There is no wood nearby and the water is from the nearby pond.
The bivouac can be reached in about 4 hours from Alagna (trail no.3) passing through the hamlets of Otro and across the pasture Alpe Pianmisura. It is the resting point before the ascent to Corno Bianco ( 3320m ) taking the eastern ridge trail, across the Tailli hill (2719m ) and the Pioda pass towards the north ridge, then across the pass “Uomo Storto” (3014m ) and the Bocchetta of Netscio ( 3280m) and towards Punta Strailing (3115m) .
