Located in the far south of Argentina near the Chilean border, Los Glaciares National Park is one of the country’s most extraordinary natural treasures. Spanning more than 7,000 square kilometers in the Patagonian Andes, the park offers some of the most spectacular scenery on Earth: towering granite peaks, vast ice fields, shimmering lakes, and—its most iconic features—its immense glaciers.
A UNESCO World Heritage Site, Los Glaciares attracts travelers from all over the world who come to marvel at its dramatic landscapes and experience Patagonia’s wild beauty firsthand. From the legendary Mount Fitz Roy to the thunderous Perito Moreno Glacier, the park is a haven for hikers, photographers, and anyone seeking a deep connection with nature.
El Calafate: Gateway to the Southern Sector and Stunning Glaciers
The town of El Calafate is the main base for visiting the southern area of the park, including the Perito Moreno Glacier and navigation tours on Lago Argentino, Upsala and Spegazzini Glaciers. With a full range of accommodations, restaurants, shops, and the Glaciarium Museum, it’s an essential stop for learning about glaciology and Patagonian history.
El Chaltén: Gateway to the Northern Sector and Best Trekking Trails
Known as the Trekking Capital of Argentina, El Chaltén serves as the entry point to the northern section of the park. This charming mountain town sits at the foot of the Fitz Roy Range and provides direct access to world-class hiking trails, mountain viewpoints, and pristine Andean landscapes. From easy half-day walks to demanding summit routes, El Chaltén is a paradise for those looking to experience Patagonia on foot.
A Natural Masterpiece: Glaciers and Landscapes
The heart of Los Glaciares National Park lies in its impressive collection of glaciers, many of which descend from the Southern Patagonian Ice Field, the world’s second-largest ice mass outside of Antarctica and Greenland.
The most famous glacier, Perito Moreno, is an unforgettable sight. It is one of the few glaciers in the world that is still advancing, creating powerful ruptures as enormous chunks of ice crash into Lago Argentino. The viewing balconies offer perfect vantage points to witness this natural spectacle, while boat trips bring you close to its towering ice walls.
Other notable glaciers include:
- Upsala Glacier – one of the park’s largest, best viewed by boat through a maze of icebergs.
- Spegazzini Glacier – featuring the tallest ice wall in the park.
- Viedma Glacier – known for its deep blue tones and accessible ice-trekking excursions.
These glaciers form a breathtaking landscape of ice and water that defines the essence of Patagonia.
Mount Fitz Roy: Patagonia’s Iconic Peak
For hikers and climbers, the northern section of the park—near El Chaltén—is a world-class destination. Mount Fitz Roy (Cerro Chaltén), rising 3,405 meters (11,171 ft), is one of Patagonia’s most iconic granite spires.
The Laguna de los Tres hike is the most famous route, offering unmatched views of Fitz Roy’s jagged peaks. Although challenging—especially the steep final ascent—the trail rewards hikers with panoramic vistas of glaciers, lagoons, and sweeping valleys.
Other beautiful trails include:
- Laguna Capri – a moderate hike with crystal-clear views of Fitz Roy
- Laguna Torre – ending at the base of Cerro Torre and its glacier
- Loma del Pliegue Tumbado – offering one of the best 360° viewpoints in the region
El Chaltén is known as Argentina’s Hiking Capital, and with good reason—there are trails for every level of adventure.
