If you’re visiting El Calafate, there’s no way to miss the vast Lago Argentino. The city sits on the shore of this massive lake, the largest freshwater source in Argentina. It covers 566 square miles and is a result of glacial meltwater, which causes its milky blue color. The lake is part of Argentina’s Glacier National Park and is home to one of the area’s only advancing glaciers, Perito Moreno, which calves into Lago Argentino.
But Perito Moreno is not the only thing to see at Lago Argentino, and many visitors choose a full day of sightseeing on the lake, starting from El Calafate. Visits up the north arm to Upsala usually give visitors a chance to see calving glaciers up close, and the Spegazzini Glacier is the tallest one in the area, at almost 450 feet. Most visits also include the Onelli Glacier, and visitors are sometimes allowed to disembark along the shores and hike among native beech forest and red-blooming firebush. On clear days, the glaciers spear stark and white, while overcast days show off their bluer tones.
