The scene seemed harmless: bright sunshine, clear skies and a calm, sparkling sea. A perfect holiday setting – and it was precisely this impression that led several visitors to make a dangerous decision. The natural pools of Isla Cangrejo in Los Gigantes (Tenerife) were officially closed, with barriers and warning signs in several languages. Nevertheless, many tourists entered the area. The result: four fatalities and at least one person missing.

Clearly signposted – yet ignored
Access had been blocked since Friday and officially prohibited, triggered by an official warning of strong waves. The signs were clearly worded. Nevertheless, around twenty people managed to get past the barriers and into the area.
The beautiful weather gave a false impression of safety. But beneath the surface, a dangerous wave system was building up – typical for this coastal region, especially with ‘mar de fondo’, a low-lying, barely visible swell.
The wave that changed everything
Shortly after 4 p.m., a sudden, powerful wave hit the rocky platform. Within seconds, people were caught off guard and swept into the sea. Emergency services arrived immediately with helicopters, boats and rescue teams. Three people died at the scene or during the rescue operation, and a fourth person later succumbed to their serious injuries in hospital. The search for one missing person continues.

Authorities: ‘The ban was clear’
The mayor of Santiago del Teide spoke of gross irresponsibility, as the closure was both visible and unambiguous. The barrier was intended to prevent precisely the kind of accident that has now occurred.
Many holidaymakers underestimate the power of the Atlantic Ocean – especially at natural pools, which seem like paradise in calm weather but can turn into a danger zone in seconds when the waves are strong.
A wake-up call for coastal tourist regions
The incident shows how urgent it is to educate people and encourage respect for nature. Tenerife experiences similar situations every year, but rarely with such dramatic outcomes. The island mourns the victims and appeals to locals and visitors alike to take warnings seriously, even when the sky is blue.
