Perito Moreno Glacier

Perito Moreno Glacier is one of the world's most accessible and visually dramatic glaciers, a constantly advancing 30-km tongue of ice and seracs in Argentina's Los Glaciares National Park, a UNESCO World Heritage site. Unlike most glaciers globally, Perito Moreno is advancing rather than retreating, and its periodic ruptures — when the ice dam breaks with thundering explosions and massive chunks calve into the lake — are among nature's most spectacular free shows. The glacier is accessed via spectacular boardwalk viewing platforms.
