The best thing in the St Kilda mule is the community of pinguins that made the corner of their home. That's the best thing to do, you have to have luck and go on a day when they really want to show themselves. Obviously, in winter it's easier but there are people who can see it in other times. It is free and there are people working in the shelter that explains the whole story and behavior of the pinguins and that's great.
