Perito Moreno Glacier

Perito Moreno Glacier is a massive and dynamic ice formation in Argentina's Los Glaciares National Park. Spanning about 19 miles (30 km), it’s a type of glacier known as a "valley glacier," carved by moving ice from the Andes. Its stunning blue-ice surface and towering walls make it a remarkable natural wonder. Uniquely, it periodically advances and blocks the surrounding lakes, creating impressive ice dams that sometimes burst with loud crashes. Visitors can witness these dramatic events and walk on its pathways, experiencing the glacier’s powerful, ever-changing landscape firsthand.
