The Viedma Glacier is the largest glacier in Los Glaciares National Park, a river of ice some seventy kilometres long that flows down from the Southern Patagonian Ice Field and ends in a broad front on Lake Viedma, near El Chaltén. It rises near the Lautaro volcano and is fed by ice from the cirque of Los Altares. Unlike the Perito Moreno, it has no walkways; it is seen from the water. Trips leave from Bahía Túnel, 18 kilometres from El Chaltén, sailing for about forty minutes with views of the Huemul massif, then landing in an iceberg-filled bay for an easy walk to a natural viewpoint over the ice front. These trips returned in 2026 after a seven-year break and run daily in the austral summer season, about half a day, with fares set by the operators in dollars; book in El Chaltén.
