Photonut, the wall you mention is actually a fence, with a gate. There is a path that leads left to Lesser Man just before the gate. It is steep! From Lesser Man it is a much easier gradient to Little Man. I agree with Ridge it is a much better way up. There is white stuff on the top of Skiddaw Little Man and Skiddaw at the moment. The Weatherline team say full winter clothing, ice axe and crampons etc should be taken at the moment. You might be ok with just microspikes but if we were going this weekend we would take ice axe and crampons too, just in case.
