Santoņa was once an island and its waters flowed into this part of the beach, but the water outlet was blocked by the action of the winds, forming a sandbank and a line of sand dunes covered with vegetation that gradually preventing the water from reaching the sea, thus creating an isthmus which is now Berria beach.
