The Perito Moreno Glacier could become the setting for the Winter Swimming World Cup 2026, an international extreme swimming event that is already generating strong criticism for its environmental impact in the Los Glaciares National Park.

The proposal includes installing a floating pool on Lago Argentino, right in front of the north face of the iconic ice giant.

Scheduled to take place from August 2 to 9, 2026, the official schedule in El Calafate includes events ranging from 25 to 300 meters and an activity called “Glacier Immersion”.

Although it is promoted as a unique tourist experience, the scale of the event raises alarms about the boundary between sustainable tourism and mass spectacle in protected areas.

Lago Argentino, at the center of the controversy

Holding a competition with hundreds of swimmers and international delegations in Lago Argentino —one of the country’s most sensitive ecosystems— implies direct and indirect human contamination.

The pressure on the area will translate into waste, water alteration, nautical transport, and the assembly of temporary structures, in an environment already hit by the climate crisis.

Specialists and environmentalists harshly question the intensive recreational use of such a fragile environment, warning about the trivialization of a protected ecosystem.

Moreover, the installation of the floating infrastructure and associated logistics will directly alter the natural landscape and the biological balance of the park.

Laws and regulations at stake

The Los Glaciares National Park is a regulated area and declared a World Heritage Site by UNESCO. In this context, the event clashes with current regulations:

• The National Glacier Law restricts activities and infrastructure that could become sources of contamination or affect periglacial environments.

• The Resolution 13/2002 of National Parks explicitly prohibits sport or recreational navigation in sectors of Lago Argentino.

While there are authorized excursions under strict controls, an international competition with floating infrastructure represents a completely unprecedented and risky scale of intervention.

An ecosystem hit by global warming

The controversy comes at the worst time for the Patagonian environment. Recent scientific research reveals that the Perito Moreno Glacier has lost the stability that characterized it: it contracted by about 1.9 square kilometers of surface in just seven years and records thickness reductions of up to eight meters annually.

While science warns about the glacial retreat, this megaproject poses a fundamental dilemma for Argentina: whether national parks should prioritize environmental conservation or transform into stages for high-impact mass spectacle.
