From one water-based attraction to another! This one is frozen, but still there are some similarities with Iguazú Falls because like the falls, Perito Moreno glacier in Los Glaciares National Park is very well served by an extensive system of catwalks that allow you to get very close to the face of this breathtakingly massive river of ice. Clearly catwalks are something that Argentina does very well! Perito Moreno glacier is located in Southern Patagonia. It’s a chunk of ice 250 km2 (97 sq mi) in area and 30 km (19 mi) in length. It’s one of 48 glaciers fed by the Southern Patagonian Ice Field in the Andes, which (by the way) holds in its icy grasp the world’s third-largest store of fresh water. There isn’t a whole lot to do at Perito Moreno glacier except walk around and get different angles on the ice, but it’s such an impressive sight that doing so is actually a fun way to spend half a day or so. If you’re lucky and patient you might see the glacier calving, which is very cool, and there are also short boat trips out into the lake that the glacier flows into if you want to get even closer to it.
