A group of adventurous swimmers gathered at Argentine Lake (Lago Argentino) in El Calafate to attempt a Guinness World Record, taking advantage of one of nature’s most extraordinary phenomena—natural flotation in icy, mineral-rich waters.
Set against the breathtaking backdrop of Patagonia’s glaciers, participants carefully entered the frigid lake, where the unique water composition allows swimmers to float effortlessly on the surface. Despite temperatures hovering close to freezing, the swimmers remained calm and focused as they aimed to stay afloat for a record-breaking duration.
Organisers said the challenge was not only about endurance, but also about highlighting the rare natural conditions of Argentine Lake, one of South America’s largest freshwater lakes fed by glacial melt from the Southern Patagonian Ice Field. Safety teams, medical staff, and official witnesses were present throughout the attempt to ensure strict adherence to Guinness World Records guidelines.
Many participants described the experience as surreal—floating motionless while surrounded by towering mountains, drifting ice, and crystal-clear skies. The attempt drew attention from tourists and locals alike, turning the lakefront into a moment of collective excitement and anticipation.
Beyond the record attempt, the event also aimed to promote environmental awareness, drawing focus to the fragile beauty of Patagonia’s glacial ecosystems and the importance of preserving them amid climate change.
