My fondest memory would be of walking along the pier with my children when they were very small holding my hands really tight because they could here and see the sea and thought they would fall through the gaps!
I really like to stand near the railings looking out to sea and see the coast out of my peripheral vision. It is like being a lot further out to sea than you are, like being on an island far from the maddening crowd. It is especially nice if the weather is very hot or the sea is very rough.
