I suggest you try contacting Councillor Stephen Gerald (see details elsewhere on this site). Best to write him a letter and drop it off in his office, as I have only once been able to meet with him during the advertised hours. He will at least bring it to the attention of the relevant authority. The fact that the situation could lead to fatalaties should get their attention, given the current situation with the beach. Unfortunately, the result could well be closure of the path.
