Cross Lago Argentino and climb a glacier-carved mountain road to a 550 m viewpoint above the Upsala Glacier, then trek into Fossil Canyon to see marine fossils exposed by retreating ice. This full-day combines boat, 4x4, and guided walking for a hands-on Patagonian experience.
More ways to explore the area's outdoor wonders
A brisk Patagonian wind meets the boat as it cuts across the glassy arm of Lago Argentino, and the shoreline of Estancia Cristina appears like raw history on the horizon. Travelers step ashore to a landscape where mountains still remember ice; 4x4s wait to climb a 9.5 km track carved by ancient glaciers, hauling passengers toward a shelter perched above the valley.
