Spain’s peak summer season has been disrupted once again by a revolting viral trend that has forced the closure of swimming pools and waterparks across the country, leaving families stranded and facilities scrubbed clean at public expense.
At PortAventura World’s Caribe Aquatic Park on the Costa Dorada this week, lifeguards evacuated both the adult and children’s pools after detecting human faeces in the water.
The incident, reported on a Tuesday afternoon and allegedly repeated the next day, left the popular resort’s aquatic areas shut for the remainder of the day under strict health protocols.
The park, which draws millions of visitors annually including large numbers of British and Irish tourists, applied mandatory cleaning and testing procedures before reopening.
One swimmer captured the scene on social media, writing: “It’s 4.33pm in the afternoon and some pig has just defecated in the pool and they’ve kicked us all out. This isn’t AI, this is reality. If you’re at Caribe Aquatic Park you’ll have seen it. We’re all out of the pool.”

The so-called “brown challenge” or “reto marrón” involves deliberately defecating in public pools or releasing faeces from bags concealed in swimwear, with the explicit aim of forcing closures.
By law, contaminated pools must be thoroughly cleaned, hyperchlorinated, and often tested repeatedly for bacteria such as E. coli. Facilities typically remain closed for 24 to 48 hours.
Health authorities warn of risks including norovirus, Salmonella and Cryptosporidium, which chlorine does not always eliminate and which can cause severe stomach illness, particularly in children.
PortAventura officials stated: “The safety and well-being of our visitors is our top priority, and our team is trained and prepared to manage this type of situation with the utmost diligence and efficiency.”
They added, “We rigorously applied all the health protocols established by current regulations and the Public Health Agency of Catalonia (ASPCAT). Specifically, in the event of any detection and presence of faeces, vomit or other visible organic waste in the water, swimming is immediately prohibited until the situation is normalised after the corresponding protocol has been applied.”
This is no isolated prank. Spanish media and local councils report that more than 300 pools have been affected in recent seasons. Municipalities from Galicia and Valencia to Madrid, Andalusia, Castilla-La Mancha and Catalonia have issued alerts.
Some towns have closed the same facilities multiple times in a single summer. Costs mount quickly: draining, refilling and lost revenue can run into thousands of euros per incident.
Fines for those caught range from €1,000 to several thousand euros, with bans from facilities, yet identification remains difficult because pools cannot install cameras in changing areas or demand ID on entry.
The Camp de Tarragona area, home to PortAventura, has been among the hardest hit. Nearby municipal pools in Vila-seca, l’Arboç and other towns have faced repeated shutdowns. Similar scenes have played out in Toledo, Zamora, Burgos, Jaén and across the Basque Country, where an Olympic-sized pool was evacuated in the middle of a heatwave.
Deliberately defecating in shared public spaces and spreading one’s own filth is not the act of a civilised person. It is literally the behaviour of animals. In nature, certain creatures mark territory with waste precisely to signal dominance, to claim space, and to drive off rivals.
What we are witnessing in Spanish pools is the same impulse, only now performed by humans who have been told their presence is an enrichment rather than a burden. When people treat public spaces as open sewers, they are asserting hierarchy in the most primitive way possible,.
This public health nuisance does not exist in a vacuum. It arrives against the backdrop of Spain’s accelerating migration crisis under the socialist-communist government of Pedro Sánchez.
In April, authorities launched a mass amnesty via emergency decree that opened the door for hundreds of thousands of illegal migrants to regularise their status, obtain work permits and move rapidly toward citizenship.
Queues of predominantly young men from Morocco, Algeria and elsewhere formed outside consulates as applicants scrambled for the required documents. The government initially spoke of around 500,000 people; applications soon exceeded one million.
By July the scale was clear: more than one million applications for legal status, granting recipients free movement rights across the entire Schengen zone.
Opposition figures, including Vox leader Santiago Abascal, accused Sánchez of engineering a long-term electoral advantage by naturalising large numbers of foreigners and altering the demographic balance.
European conservatives warned that the policy risks collapsing Schengen itself by allowing unrestricted onward travel. The New York Times, for its part, hailed Spain as a “beacon of the global left.”
That same open-border approach has played out dramatically in the Spanish enclave of Ceuta. In late July and early August tens of thousands of mostly military-age men crossed from Morocco in a matter of days, overwhelming local services.
Beaches became open-air camps littered with waste. Hospitals reported outbreaks of scabies, measles and other infections. Police and military personnel assigned to clear the sites themselves contracted scabies.
Despite official claims that most would be returned, thousands remained, and the cycle of clearance and reoccupation continued. The visible impunity has emboldened further attempts to reach the Spanish mainland.
Just days ago, dinghies packed with North African men landed on tourist beaches near Cartagena, sending holidaymakers scrambling for their belongings.
Local mayors expressed fury at the ease with which the vessels reached shore undetected. The message from Ceuta appears to have travelled: if thousands can simply walk or swim into Spanish territory and face little lasting consequence, smaller acts of disruption elsewhere become easier to attempt.
The “brown challenge” sits at the intersection of social-media exhibitionism and the broader erosion of shared standards that accompanies rapid, unmanaged demographic change.
Public pools and waterparks are among the last remaining low-cost spaces where ordinary Spanish families and European tourists gather in summer. When those spaces are repeatedly rendered unusable by deliberate contamination, the social contract frays further.
Taxpayers fund the clean-ups. Parents keep children away. Businesses lose peak-season revenue. The pattern is familiar across Western Europe: facilities built by one population become contested or degraded under pressures introduced by another.
A country that once marketed itself as a premier holiday destination now contends with closed pools, stormed beaches and the quiet calculation by many natives that the old rules no longer apply equally to everyone.
