The south approach is not done so much, so we can't tell you too much about this route. It seems to be a straightforward way to access the upper reaches of Monte Cristo. The specific requirements of the route are not known. The upper reaches of the peak are likely to have have moderately steep snow and a bit of 4th class rock. (Sorry this is vague, but that's all we have to go from the original exploratory climb prospectus!)
