The path just follows the reeds/bamboos 'straight South' to the beach.  On satellite pictures you can see the start coming from the sea, it's a 'road' that seems to give access to a house/a plot, but then this wide bit ends and the footpath continues from there 'due North' up to the sharp bend in the camino del Barranco de Enmedio.
