There are beach walks which you do with kids - the public toilet is not improbably far away, the water is shallow, the surfaces are sandy, and the shore is littered with interesting bits of seaweed and shells.
There are beach walks which you do with friends - a bit like the above, but with plenty of potential bonfire locations and enough towel space for everyone.
There are beach walks which you do with a lover - a bit more remote and less family-friendly, no surf to speak of and preferably free of distracting nudists (which, come to think of it, applies to the kids' beach walk but not so much the friends' beach walk).
And then there are the beach walks you do when loneliness weighs heavily on you and you desperately need to be soothed by the sound of waves lapping against the shore. It doesn't have to be remote (my own LLWBTB is next to 4 lanes of traffic speeding to or from the airport), but it can't be very popular. Because all those people and their chatter get in the way between you and the water sounds. If it's lined by magnificent pieces of public art, then all the better to give you an alternative subject of contemplation.
Even though we might wish we didn't need a good LLWBTB, we should be glad to have one.
