Prohibited Place
When you reach the southern viewpoint at the Cliffs of Moher you'll find a sign warning for going too close to the edge of the cliffs because there are no protective fences. It's not that I want you to ignore that law because it's a way to keep you safe from falling into the sea. If you approach the edge there is no danger, except if you go there with kids, it could be a little dicey for them. No one or almost no one gets too close to the edge.
