4 min 20 sec at Playa de Zamora, La Palma, Canary Islands

I stuck my camera in the black sand beach and recorded a few minutes of the view and the sound. I was going to go longer, but a sunbather walked into the view.  The person visible at the beginning is not me.

So peaceful! I hope the weather was warm enough to swim in such beautiful aquamarine waves!
