Argentine Patagonia stretches from El Calafate's Perito Moreno glacier calving into Lago Argentino to El Chaltén's Fitz Roy massif, the whale-watching at Península Valdés, and Ushuaia at the world's southernmost city.
Patagonian summer with Fitz Roy and Torre summit windows, Perito Moreno calving daily into Lago Argentino, and Ushuaia accessible as the Antarctic cruise gateway.
Spring shoulder with whale watching at Península Valdés peaking with calf season, El Chaltén trails clearing of snow, and lower rates than peak summer.
Autumn brings lenga forests turning red across El Chaltén and Bariloche, Perito Moreno at peak photogenic, and the trekking season closing without summer crowds.
Patagonian winter with Cerro Castor near Ushuaia and Cerro Catedral at Bariloche running ski operations, and Fitz Roy region inaccessible to standard trekking.
