Tourists have been handed a serious warning about pollution issues on 48 beaches across the Spanish coast.
A total of 48 Spanish beaches have been hit with a 'black flag' notice for pollution issues, including chemical spills and dog poo.
The Mirror reports that these sandy locations were named by Spanish environmental campaign group, Ecologists in Action.
This campaigning group hit out at local authorities for not protecting the coastal locations from invasive developments and pollution issues.
Many of the beaches on the incriminating report are popular spots with tourists who visit the hot destination.
One beach on the list, A Calzoa in Vigo, on the north west coast, has been described as the "worst dog beach in Spain", according to The Sun.
As reported by local media, this beach has become a "sandbox for dogs", with the outlook ruined by dog mess.
Beaches that were also listed in the report include some in Malaga, as well as locations in the Balearic Islands, Canary Island and Basque Country.
Some 12 of the black flag notices were due to chemical spills, purification issues and faulty sanitation, Ecologists in Action said.
A further six beaches were listed due to light, chemical or noise pollution in the report.
A number of the issues on these Spanish beaches have been caused by invasive development of land and poor authority management, as noted in the report.
Last month, we reported on Spain's top 10 unspoilt beaches, following a study by Avis.
The company scoured three million Google searches to pinpoint the most secluded Blue Flag beaches in the country, perfect for anyone wanted to escape the crowds.
At the top of the list is Os Frades beach, in the hills of the Baiona coastline - a small beach that is known for its crystal-clear water and stunning views.
Ezaro Beach is another unspoiled spot located on the west coast of Spain - surrounded by cliffs and is only accessible on foot.
The beach is located near the famous Camino de Santiago, which is a pilgrimage route that dates back to the Middle Ages.
