Lay on the beach in Spain

Spain is the hottest country! I mean its spirit. I also know that this is a clean and well-conditioned country. I learn Spanish in order to go there and to be able to ask where is the coolest place here?(donde esta la localidad cool)-something like that, actually I study it not for so long.
I want to visit Cantabria first, as this is one of the beautiful places in Spania!You can read a text about it.
