Almost 50 famous beaches in have been given unwanted black flags - rendering them unsuitable for swimming.

These beaches were given this unfortunate title by the new environmental campaign group due to ongoing and untreated ecological issues such as chemical pollution, marine waste, overdevelopment, and sewage discharges. In June last year, the annual report saw 48 beaches awarded black flags, including those in popular destinations such as Malaga and Costa del Sol, and locations on the Spanish islands of , Tenerife, and Lanzarote. A new report for 2025 has not yet been issued.

Out of the 48 listed beaches, 15 faced issues due to overdevelopment along the coast, while 16 were reported to have poor wastewater management, resulting in pollutants and contaminants not being effectively eliminated from the ocean. An incredible 5,000 mile span of Spain's coastline was examined to reach such a verdict.

Talamanca Beach in Ibiza appeared on the list after being highlighted for the catastrophic damage inflicted on underwater plants by boats anchoring illegally off the coast. The report also mentioned the impact of a treatment plant discharging salty wastewater into the sea on the beach.

Additionally, El Amerador Beach in El Campello, just north of Alicante, also received a flag due to disease-causing faecal pollution attributed to a nearby poorly maintained pumping station. Meanwhile, the Canary Islands' beaches have been inundated with litter from tourists, leading locals to protest last year. However, Ecologists in Action confirmed that it wasn’t solely the tourists to blame; major sewage companies also contributed significantly to the damage.
