Beautiful & impressive as they are, in a way the Cliffs of Moher are hard to see, that is, to get a fresh view of. The paths are laid out for walkers, no behind-a-rock surprises. Like the Pyramids in Egypt, they've been stared at so long that there's not a lot left to see.
I don't mean to say that I was disappointing. Beauty is enough. Beauty is always all we need.
