In reply to MrRiley:
As MrL says Lurchers is a bit different to the to the other crags in Cairngorms as it is more 'water ice'. This means that it takes low temps to come into condition, though sometimes it can be 'in' when other places are out.
I've been lucky and been able to park at Rothiemurchas lodge in the past, where an alternative to walk from the Ski Lodge is to walk up from the gate to Rothiemurchas on the main road, just before the lake.
