The South Ridge is another established mountaineering route on Mont Valier. It is a mixed alpine ridge climb with scrambling and exposed sections, and it is more serious than the normal hiking approaches to the peak. Snow or verglas can make the route considerably harder and more committing. The line is best treated as an alpine climb requiring stable conditions and route-finding ability. I am not confident enough to provide documented numerical figures for gain, length, or times.
