Discover more about Viedma Lake

Viedma Lake, cradled within the magnificent Los Glaciares National Park, is a Patagonian spectacle that captivates with its serene beauty and dramatic glacial landscapes. Stretching approximately 80 kilometers (50 miles) in length, this elongated lake is fed by the Viedma Glacier, a colossal river of ice originating from the Southern Patagonian Ice Field. The lake's mesmerizing turquoise hue is a result of the glacial meltwater, laden with fine sediment, reflecting the Patagonian sky. Named after the Spanish explorer Antonio de Viedma, who first reached its shores in 1783, the lake offers a unique blend of tranquility and adventure. Visitors can embark on boat tours to witness the towering ice walls of the Viedma Glacier up close, marvel at icebergs calving into the lake, and even trek on the glacier itself with guided excursions. The surrounding landscape is a testament to the power of glacial activity, with rugged mountains, steep-walled valleys, and sparse vegetation sculpted by millennia of ice movement. Located near the charming town of El Chaltén, the 'National Capital of Trekking,' Viedma Lake serves as a gateway to numerous hiking trails and outdoor adventures. From the lake's shores, you can admire the iconic peaks of Mount Fitz Roy and Cerro Torre, offering unparalleled photographic opportunities. Whether you're seeking a challenging glacier trek or a peaceful stroll along the shore, Viedma Lake promises an unforgettable Patagonian experience. The lake's western shores border the Southern Patagonian Ice Field, an area where the international border remains undefined. The Viedma Glacier, the lake's primary source, is the largest glacier in Argentina and the second largest in South America. Its terminus, a moraine-rich wall of ice, stretches approximately 2 kilometers (1.2 miles) wide as it enters the lake, creating a dramatic spectacle of calving ice and ever-changing glacial formations.
