Glaciar Perito Moreno and the moving wall of Patagonian ice
Published on 09/23/2026 at 22:32 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Glaciar Perito Moreno reaches Lake Argentino as a vast, crevassed wall of blue-white ice. The glacier lies inside Los Glaciares National Park, west of El Calafate, where the Southern Patagonian Ice Field meets lake, mountain and steppe.
Glaciar Perito Moreno: a glacier ending in Lake Argentino
The ice front stretches for about 5 km and rises up to 60 m above the water. Behind it, the glacier extends roughly 30 km through the southern Andes. Its surface covers about 250 km², while ridges, crevasses and fractured ice mark the route towards its higher catchment.
The glacier enters a narrow arm of Lake Argentino beside the Magallanes Peninsula. The meeting of ice and water gives the landscape its clearest form: a high frozen edge, a grey-blue lake and mountains beyond. Blocks can break from the front and fall into the water, producing icebergs that drift across the lake.

From the Southern Patagonian Ice Field to Patagonia’s lake country
Glaciar Perito Moreno is connected to the Southern Patagonian Ice Field, an extensive body of ice shared by Argentina and Chile. The ice field feeds glacier tongues that descend towards large Andean lakes and valleys.
Los Glaciares National Park occupies the south-west of Santa Cruz Province in Argentine Patagonia. Its protected landscape contains glacial lakes, granite peaks, forests, Patagonian steppe and high-altitude vegetation. Lake Argentino, with a length of 160 km, forms the broad water landscape beside the glacier.
The park covers 600,000 hectares and became a World Heritage Site in 1981. Its protected area records geological processes linked to repeated glaciation, including lake basins, moraines and glacier tongues shaped by advancing and retreating ice.
The Los Glaciares World Heritage site includes Perito Moreno, Upsala and Onelli glaciers among its principal glacial features.
Francisco Moreno and the name of the glacier
The glacier takes its name from Francisco Pascasio Moreno, an Argentine explorer, scientist and surveyor of Patagonia. The title “Perito” means expert or specialist in Spanish and refers to Moreno’s work in border commissions between Argentina and Chile.
Moreno was born in Buenos Aires in 1852. His geographical studies, collections and journeys helped place Patagonia within Argentina’s scientific and political history. The glacier received the name Perito Moreno in 1899 during hydrographic surveying in the region.
The surrounding national park carries the same historical landscape of exploration, mapping and conservation. Los Glaciares National Park was created in 1937, and its boundaries include a large protected area extending from the Patagonian steppe into the Andes.
Glaciar Perito Moreno therefore carries several layers of meaning. It is a physical part of the Southern Patagonian Ice Field, a named feature of Lake Argentino and a place linked to Francisco Moreno’s nineteenth-century work in Patagonia.
Visiting Glaciar Perito Moreno: what travellers from Western Europe should know
- Glaciar Perito Moreno lies west of El Calafate in Los Glaciares National Park. Road access follows the route towards the Magallanes Peninsula and the glacier viewpoint area.
- The approach includes organised walkways and viewing terraces above Lake Argentino. The terrain combines steps, slopes and exposed mountain conditions.
- Boat excursions operate on Lake Argentino and present the glacier front from the water. Other activities reach the ice itself with specialist equipment.
- The official language is Spanish and the currency is the Argentine peso.
- Entry requirements depend on your nationality; UK travellers can check the FCDO travel advice at gov.uk/foreign-travel-advice, Irish travellers the Department of Foreign Affairs at ireland.ie.
