Cliffs of Moher, Ireland
Don’t confuse the name with cliffs of mother, though it does seem like the mother of all cliffs. If they don’t seem impressive enough to you, they rise 390 feet above the Atlantic Ocean and reach a maximum of 702 feet.
Cliffs of Moher are no regular cliffs, but celebrity cliffs. It was featured in several films including The Princess Bride (a personal favorite) and the Harry Potter franchise.
