The dunes shelter as well the Atlantic Linaria polygalifolia subsp. polygalifolia, and the Omphalodes littoralis subsp. gallaecica, only found in the northwest of Galicia. 

The Neme mountain rises from the village of Razo providing a wide view of Baldaio, Malpica and the Sisargas Isles, Buno, Carballo, and, far away in the north-east, the Cape Prior in Ferrol. Neme and Baldaio's sky is watched over by the Corvus corax and Falco peregrinus. 
  
According to history, early Galicians chose this place for religious rites, as it is pointed out by the place name " Neme " that means sacred in the old Galician-Celtic language. In the summit of the mountain there was a cromlech known as "Eira das Meigas" (land of witches), about which traditional tales say that the stones were used as seats for the witches who met there. The stone circle was destroyed in the wolfram mining works during the II World War.
