Mike said "isn,t that the beach you reach after traversing the bad step?"
Absolutely right Mike. The Bad Step is the slanting crack over the great slab of gabbro. The first time I came across it, it was getting dark, the wind was howling and it was pouring. Not only that, we had huge, top heavy rucksacks on our backs. It is just about unavoidable on the shore path from Camasunary into Loch Coruisk. There is supposed to be a high level alternative but I have never met any one who has found it.
Here is another shot with a lone scrambler to give scale. It is a fantastic spot.
