A cold wind greets the pier at first light as the Fitzcarraldo cuts a path into the South Arm of Lago Argentino. The boat’s wake glitters an emerald that seems to push you toward the granite ribs of the Andes; disembarking at the southern head, the forest swallows the engine noise and the real journey begins.

Conservation
This area lies within Los Glaciares National Park—stay on marked trails, pack out waste and follow guide instructions to minimize impact on fragile moraine and tundra.

Expect wind-driven changes
The South Arm is exposed; operators may alter the landing or picnic location if winds are strong—pack quick-dry layers and a warm hat.
Footwear matters
