Pick a line, any line! The easiest line is probably from the summit to just above the col with Carn Dearg Meadhonach. In lean conditions, a tongue of snow usually extends low into the corrie by the stream line. In good conditions, you can more or less ski/board anywhere.
The summit area sits on a cap of scree, that has a short craggy section below it. In good snow conditions, it's possible to find a way through the rocky section to the slope below.
