Sherlock Holmes

A fun and nice experience to stop and check out for maybe an hour. Swimming is allowed but at own risk. There are toilets and a parking. Beware that there are little fish and when you stand still in shallow water, the fish detect your feet or legs (the skin, maybe small particles, dead skin etc.). They come to them and nibble/bite/suck lightly. Because you are not moving, the fish feel safer / undisturbed and will approach. If you swim around or move, they often scatter. Its a funny tingling sensation and not harmful.
