From Puerto Bandera, board a boat heading into Los Glaciares National Park across Lago Argentino. The turquoise color of the lake's water, produced by glacial erosion, won't leave you indifferent.
After navigating several arms of the lake, the boat approaches the Spegazzini glacier, whose walls reach up to 125 meters in height, the tallest in the region. This ice mass covers 66 km².
Disembark at Onelli Bay to make your way up to the glacier of the same name, passing through a Tierra del Fuego beech forest.
Weaving between icebergs, approach the Upsala glacier next, the largest in Patagonia; this giant of ice stretches 50 km in length over an area of around 860 km². You'll also pass the Perito Moreno glacier, the most famous in the region — a legend in its own right!
Lunch is served at Estancia Cristina, from where you'll have the option of a trek or a 4x4 tour to take in the extraordinary views over the ice fields.
