This is one of the highest rampant dunes in Europe. This set of dunes, which is almost 2 kilometres long, is visible from the Monte Blanco viewpoint, where we will get a great panoramic view of Barra beach and the entire coastline. It is also in these dunes where a key flora is born to fix the sand, highlighting the presence of Omphalodes littoralis subsp. Gallaecica, in danger of extinction.
