Beach amidst meadows

It is interesting to know how this beach was formed? Where the water? And it is the sea. Any suggestions?
Let us learn the truth as quickly as possible.




This unusual beach hidden among the high hills of Spain, a few hundred meters from the sea. Pond natural tunnels connected with the sea, so the water is not stagnant.
