Los Glaciares National Park is located in the Argentine part of Patagonia. Los Glaciares owes its name to the numerous glaciers covering roughly half of the large property. The National Park is an area of exceptional natural beauty, with rugged, towering mountains and numerous glacial lakes, including Lake Argentino, which is 160 km long. At its farthest end, three glaciers meet to dump their effluvia into the milky grey glacial water, launching massive igloo icebergs into the lake with thunderous splashes. The park has two distinct regions, forests and grassy plains in the east and needlelike peaks, lakes, large glaciers, and snowfields in the west. Mount Fitzroy, 3375 meters, is the highest point in the park. Wildlife includes guanacos, chinchillas, pudu and guemal, condors, and rheas.
