The "Toilet Bowl" formation is just behind Olga here, at the bottom of the cliffs. The seas were calmer than usual when we were there, so the swirling action which gives it its name was not as apparent as sometimes. However, you can still see on the following video how water passes through a semi-circular tunnel to surge into a hole (the "bowl"). Imagine what this may do if the waves were just a bit more powerful, and I think you will agree that Toilet Bowl is an apt name for this formation.
