It is approximately 500 m long, is an area of great scenic beauty and is of great ecological value. Originally, behind the beach, there was the most extensive dune field in Asturias, which penetrated inland for almost a kilometre.
Nowadays, the dune system of El Espartal has a very obvious first line, up to fifteen metres high, behind which there is an extensive dune field in which it is difficult to recognise the successive lines of adjoining lines.
