The most massive glaciers in the Southern Hemisphere outside of Antarctica can be found in Patagonia in Argentina. Just seeing the glaciers is a great reason to visit Patagonia. The incredible 3-mile vast Perito Moreno glacier in Argentina Los Glaciares National Park cannot be captured adequately in a picture. Its immense, icy blue beauty can only be truly experienced firsthand, from viewing platforms or, ideally, the trails that allow hikers to get up close and personal with the glacier. If you dare to step onto part of the glacier, you’ll be amazed by the lagoons and ice caves you’ll encounter.
